Free 454 big block teardown 

I own 4 snap on ratchets and set of sockets. Brand new never used em yet. Probly never will. Also own many sets of Carlyle gearwrench Icon and i use a large case of channellock for my normal wrenching now. I learned to not get all caught up in expensive tools because they end up getting dirty. Thats why now i like using cheap tools that i don't care less if they get dirty. I will use my nice tools for clean engine assembly though. Honesty its hard to beat them Pittsburgh from harbor frieght. Cheap enough not to give a s-it about, but actually are very durable sockets and wrenches etc. And if they do break... i got about 5 harbor frieght stores within 15 minutes from me to return no questions asked. Cool video. I just bought and pulled a 454 from U-pull R parts. $278! Tore down to find out its like brand new inside with super clean .030 pistons cam, rod, main bearings. Crank been turned. Heads and valves absolutely clean!!! Stock timing chain trash though. Crank been polished. So im doing a rebuild with new bearings and rings anyway. Thoroughly clean the block etc. Performance build with XE284 and PRW roller rockers. RPM air gap. Springs etc. For hot street engine. My engine the 5151 casting. Early mid 70"s. Complete balanced reciprocating assembly. Cant beat that for $278!😊

Cool tear down. Funny, I purchased the same motor just recently, somewhat redone, and have since rebuilt it to my liking, I just wish it was found cheaper, I paid $2,000. My block is a 959 casting also poured in '78, it is now .030 over. It had the 236 peanut port heads, I ditched them for a set of 820's for $100, worked for another $100, I just wish they were lighter for the suspension's sake, though I got big block springs, '71 Chevelle. Pistons are Speed Pro H426CP's. Cam is a Howards 122121-10. Intake is a 7561 edelbrock RPM Air Gap. Carb is an Edelbrock 1411. I am running a 200-4R and a 8.5 - 3.73 - 10 bolt. It sounds great and I sure do like it. Cool just to watch every step and learn for future events. The car had a .060 350 in the which I'd like to stroke some day just to play around with some, maybe put it in something else.

Oval Port Castings ending in #781 or #049 are the good ones.

Wish I could get a free 454 with 781’s, good heads. 👍🏻

Most core big blocks now are 500+ and you got one for free, nice

Finding a gem always feels good

Well done.

I wish I was lucky enough to get a Free 454

Great video, I really enjoyed watching! Make sure all the main caps, especially the #2 that has the bad bearing, snap into their registers snuggly. The block’s mains can be line honed/bored to bring the mains back into spec. With some short dome (1/8”) cast pistons you’ll get close to 9:1 with those heads and make tons of torque! You can grab a used crank from a 366, 396, 402 or 427 which are all 3.75” stroke. That would give you a 427 :)

the 781 heads are the best flowing factory cast iron large oval port heads chevy ever made ive seen them make 600-650hp with the put in the bigger valves 2.190 intake and 1.880 exhaust. Im making 600hp on my 496 stroker with 781 heads

The best chevy engine ever built the big block chevy 454

Blocks std bore its all factory its 4 bolt main light weight block yes i see it two peace Blocks

Crank kit time

781s are one of the best heads for that era. Heavy but great for street engines. They are oval port heads.

Tables, son. Tables. How many extra steps did you take?? 🤣

why always stand up the crank just curious

When all things are equal a 327 does not make more power than a 350. That's an old wives tale. What did you end up doing with this 454?

Nice that it was free......Nothing other than the block I would reuse ..454 makes much more power than a 427.... good luck

Maybe the engine had been rebuilt at some point.

clean up the anti freeze instead of walking threw it might be a good idea

Damn that's a score there .didn't see rotators ,have the shop check springs you may be able to reuse them choose non emissions cam based on headers or manifolds auto or manual External balance there so make sure flex plate is right for what ya do. Don't put a 427 crank in it

If the rest of the engine is good you can pick up used stock rods for next to nothing and crank too the send to machine shop .Not that expensive . It is definitely worth rebuilding .

74.4 lbs WITHOUT about 4 pounds of rockers. And I would be more worried about a cam or crank falling over that bending while it's just sitting still.

I have a 454 with a turbo 400 in my RV it has 60k miles on it runs good I haven't ran it sense I parked it here at the RV park 3years ago I live in it and Im moving in to a new camper so I'm just gonna sell the engine or the whole thing .if interested get in touch with me

It is in your mind when all things are equal the 454 makes more power as does the 350 , but 327 could sound cool I guess 427 also
