Turn a CHEVY 350 into a 421? 🔥 Ed Smith Engine Q&A with BarryT  

Extract as much knowledge as possible from these legends. Ed you’re amazing, and a delight to watch.

Old school dudes like that will be missed when there no longer with us

I wish my doctor knew as much about my body as this guy does an engine.

This is what we call knowing his stuff.. that is a brilliant mind

Doesn't matter what the old guy's are doing watch them. My boss is 93 he can't remember what he did 5 minutes ago. But I listen to his stories he remembers what works

Doesn’t even pause… this stuff just rolls off his tongue. That’s knowledge.

With age comes wisdom, no calculator, no google, just experience and this guy is eat up with both wisdom and experience!!!!

Guys like this are rare to find these days and will be missed.

this guy knows his stuff

Very knowledgeable. Love this man. I wish I could just sit beside him for a month and learn as much as I could.

This man has forgotten more then most will ever know. A true legend !!

Former Circle track racer here. Ran a 350 punched+.100 for several years, had no issues but it was a early 1968 heavy 2 bolt block, don't remember the # but it wasn't a common 010 or .020 block. Core shift is a bigger problem on later mid-70's blocks. Late 70s, 80s light weight blocks may not go +.60 reliably for this and other reasons. In late model my 421 was a 400 block, +.40, with a 3 & 7/8 stroke. Also ran a 392ci, 400 with a 3 &5/8 stroke, very versatile engine. A good 355 is under rated, works well on a slippery track. Wanted to try a 388 but never got the chance. If you want to go with a 4.0 stroke best buy a aftermarket block with a raised camshaft bore for more clearance for the rods. Had various 355,358, 377,383 and 406 combinations of cheap, stock (and some not so stock) parts engines and had the best success with the short 400 rod 383 in a limited car. If you want more than 6000 RPM you need good aftermarket rods, not just good bolts. Tru$t me!

Please keep uploading these videos. Knowledge from a bygone era. In the limited time I have left, it has been a pleasure watching these clips.

Dude is a national treasure !

I had a 61 corvette with a 283 bored .125 never had a problem. We called them a 301.

So much knowledge. Got to respect this man.

That's what I love about old-timers, they've got that wisdom aid that priceless experience. You can ask them questions and it's yours, they tell you everything you need to know, things you won't find in a textbook, it's amazing.

I wish I could just keep all this information in my head all the time of all these old-timers I try to watch much as I can and write down !

This guy is a sheer joy to listen to and gain unheard of mechanical knowledge

Beautiful, proves that you can't buy experience , you EARN IT.🇺🇸

These are the type of dudes I grew up with. Legends man

He knows his sbc's no doubt !

I love that he is giving us his lifetime of knowledge here. It’s absolutely invaluable and an entire library worth of information. Thank you. We learn so much. He’s so smart

Another short I just saved. I like to go back to Ed from time to time. You just gotta love this man.

I love to sit with this guy, drink some tea, and talk motors all day!!!!❤

Love how old cats can just sit and spit facts!

This gentleman has so much knowledge I hope he cares it for future generations and the are others who want to learn

Pay attention to these people. They speak volumes of knowledge

❤ what a wealth of knowledge ! Thanks 👍

Years ago I worked in a machine shop. We built a 427 small block. It's really not that hard to do. Like Ed said, you better have the right block.

This gentleman knows so much.

All this knowledge needs to be preserved for future gearheads.❤👍🔥🇺🇸

He's totally right. .60 over is the well known max on the blocks though. Not all blocks could handle .60, due to core shift or thin castings. I've never seen a bad block, but I've only built 5 or 6 .60 over blocks. He absolutely knows his stuff.

I had the good fortune to work in a hot rod machine shop when I was young. I helped source parts for builds and spent some time doing this kind of math. So much fun. Dart made back then extra-thick small blocks that could be bored and stroked to get up to like 434 ci

So much knowledge it's awesome to listen to you talk Motors

Gotta love the guys who will sit and answer all these questions. Not complaining that "you can google that" or "look online". Yes the answers are all out there. But it's not the same as when someone really knowledgeable sits down and takes the time to explain

Grind that block baby, that’s how the stroker was made! He’s old, and he knows stuff, god bless him! 🇺🇸💪👊

I love old g like this, really knows a lot about engines and life 💪🏿💯

This legend forgets more than most car guys know!!😎

Listening to the knowledge just oozing out of this old timer is just a treat for me.... I used to hang out with all the hot heads in the shop listening to them and the motors they've built. Amazing!

This man has forgotten more about engines than most people will ever know.

If you go from a 4.000 inch bore to a 4.100 inch bore isn’t that 100thu over not .060 over????

This guys is the last for a breed that isn’t made anymore. Love and respect! Swear to gawd I thought this was a q & a with my grandpa and I years ago. He was sure as day and I was asking Any and everything because I wanted to know everything he knew. And that would never happen, the experience is what couldn’t be taught….. but hell I love this! Keep the good videos coming! Y’all be blessed!

These men are the best. Pure knowledge

A 350 can become a 434 ci Stroker! He is correct, use the right block! But then again you always should

Guys like this are a dying breed

I would love to talk to this guy or lunch. The wealth of knowledge is invaluable. Please record more of this gentleman sharing his knowledge. Love it.

Love to listen to these old timers they have so much knowledge that hopefully gets passed down!

That ole boy knows motors no doubt.

This guy is incredible, I wish I was as smart as this fella

Nothing replaces the wisdom of experience.

Nothing but respect for this guy 👏

This is why the SBC engine still lives 😊

Guys like this inspire me to build whatever I want. I love it

Love this guy

I have a lot of respect for guys like Ed. 💪🇺🇲🤘

Pure KNOWLEDGE !! WHEN YOU GOT IT, YOU GOT IT!!! GOD BLESS

The knowledge these old timers have MUST be passed on!

This man needs to write a book or something, he is smart as and guarantee he’s worked on everything under the sun

A lifetime of true knowledge

This fellow is really smart like motor wiz wow , it amazes me how folks are so smart on engines.

His knowledge is so damn impressive

Reminds of my Uncle, who was a diesel truck mechanic in Indiana and had the same wisdom & knowledge of motors...( Diesel's especially)

Ed said hell .060 is just a cleanup cut in my days

I Ve listened to this 15 times it's just makes me feel happy

I wish my algorithm would switch to more of this

Legendary knowledge there.

That is one man with his knowing stuf. Soooo cool.

He knows his stuff just by taking about it

REAL OG. Knows his shit. Love guys like this. Shot out to Diesel Dave in my shop!!

Would love to have this man build my 350❤

421ci Thats what everyone is building today for drag racing but I believe they start with a 400ci Chevy

People wish to meet celebrities, I wish to hangout and have coffee with men like this guy so smart and it's just basic knowledge to him I seriously love it

OG knows his business ❤

New Dart SBC Block best way now as thick older blocks from 60s, 70s rare

Love this man

He’s like the Dr. Frankenstein of engine builds😊😊

Smart man!

He’s the kinda guy to ask now what kind of carb would you like?

These older generation guys have knowledge you'll never find in a book. I'd love to work with a guy like this. Most of them have given up on passing down their knowledge to the young guys. It's sad.

The turnover of knowledge and experience from generation to generation may have already been lost but i applaud any and all documentation in any and all industries that even after the fact make it happen.

The man knows his shit I was raised by a man just like that with my grandpa I was old schooled all the way you must learn something from these elder people and you might learn a lot wake up America

My very first engine build when I was 15 was the same stroker. I had a 400 crank in a 350 and long rods. Had Venolia make me some pistons and used some Corvette aluminum heads. This was back in 1988 and the Corvette alu heads were fairly new but you could get them from GM for a good price. The long rods have a better rod to stroke ratio. Hat Rod magazine did one they called the "406 Strong Arm" and they used Brodix heads.

Just like watching some old time butchers cut up a cow. There’s DEFINITELY some magic in these older guys who’ve been doing machine work ALL their lives. MUCH respect to ALL of them

Lol you gotta pick the right block, hmmm been saying that since the 2 bolt vs. 4 bolt debate

I have known a man who used to build Indy cars years ago He thought me the harder the material the slower speed of the Drill bit .

Wow 😮

Dont forget to grind the block sides to make room for that 4" throw of the crank. Otherwise it will hit.

Bro is a library of auto engine info.

I will take " People who know their craft right as rain" for a thousand Alex.

Picking the right block is key.. zero core shift... Can be seen at the front and rear of block.. concentric around the cam bearing is the best way to tell.. 1182 main caps..

I've had em bored out .080 over. 4 bolt mains and forged internals. 85 square body with 36 in swampers.

Great knowledge!

You can see the moment his mind leaves the room and sits down to an engine in the stand and pulls the rod out so he can inspect it in his mind.

I’ve never heard or seen anyone do this with a 350 small block Chevrolet engine.

The Master✊🏻💯

You need an aftermarket block with raised cam and widened pan rails to fit a 4 inch stroke, and most likely to get 4.092 bore also to get your 421. Would be simpler to use a 400 block with 3.875 stroke and 4.155 bore.

Good video thank you

A 10/20 (high nickel) 2 bolt main block with splayed 4 bolt mains and centered cam hole. It will rock and with a good rotating assembly, 904 lifters, and some good heads should turn 10 grand or better.

So much experience behind those eyes. #bottlethatup
