Very smart to go 3.75 on the stroke, that engine will last longer and not beat the piston skirts as much given the short deck block. The 4.00 stroke of the ls7 was designed for a taller deck height of the block. Those 408 combos don't last along due to the piston rocking at bdc

@JacobVillemain Год назад

The deck heights are actually the same between an LS7 & 6.0 block. The sleeve length however is much longer in the LS7 block to support the piston. However, I do have about 5,000 very very hard high rpm nitrous miles on my 4.000" stroke 6.0 and the piston skirts still look awesome. As long as the bore is perfectly straight and properly de-burred at the bottom the piston skirts will last a very long time.

@mgrijalvaespinoza Год назад

Very cool! Very unique build. I went the usual 383 off an Ls1 block since I already had the block from my 2000 B4C Camaro😏. 👍

@GrandPitoVic Год назад

Very nice brother. I like different. That engine is beautiful. I can't wait to see the 632 on the dyno as well. HELL YEA!!!!!

@brianross4057 Год назад

So it's basically a bit more than an LS3 in capacity with a shuffled bore and stroke combo be interesting to see if it makes much difference against an LS3 with same heads and cam with respect to efficiency and power - torque curves.

@robertbailey3057 4 дня назад

2:37 IMO...what id do is throw an ls7 based head that accepts a 4.030 bore CID, and GPI make one. That way you get the larger intake valve, raised runners etc. With the slightly larger crank stroke it will add some two down low & you can run 6.2-6.3 rods which will help you run it out for higher rpm. The LS7cylinder heads, as well as intake manifold( CID single plane,or, LSXHR) promoted good mid and high rpm power. Pair that with a comp cams LSR 235/251 cam and you'll have a sick set up that has a large broad rpm range of non stop tq & HP! Run a nice 10.1:1 Diamond pistons. Add a simple D1X Procharger kit/or/ Vortech V7-YSI kit if you prefer. That would be a nasty street/ strip car

@natewoods6494 Год назад

If I had a 5.3 block and couldn’t get a 6.0 block then i would do a 383. But for . 6.0 I would want the 400+ cubic inches. I can still appreciate the build though, old school bore/stroke ratio

@zxtenn Год назад

Great video... With Today's technology i think looking for say 500 usable HP for something like a 1st generation Camaro using a small block would be the way to go? Less weight and for a street driver seeking plenty of drivable performance and not looking for a cage i assume something like a 572 would be too much for the unibody to handle even with frame connectors.

@63chevyll30 Год назад

molnar recommended the same crank, rods and pistons for my build, with a "custom" cam from bullet, warhawk heads and 2 66mm turbos it made 1235hp at the tire with 24lbs of boost.

@pablotharpalo5685 2 месяца назад

That would be awesome to see! I don't think technology has come far enough though for us to have anything greater than a 4.220 on a small block yet, however

@whereisamerica7384 2 месяца назад

@@pablotharpalo5685 you can do a 4.250" on an LSX block, but they say for NA only. I've talked to a couple machinists who claim you can do certain stock blocks with aftermarket sleeves. I want to try one at some point. It may have to be a slightly smaller bore though. 4.185-4.220".

@erichunt9837 Год назад

The short stroke engines can really be advantageous especially under boost. The 4.00 stroke setups tend to wear out piston skirts due to the short deck height

@rileyzandol3150 Год назад

He’s got a huge connecting rod in that thing too. If it’s na this engine would last like an old tractor. I bet it would be a 300k 500+hp fire spitter

@jamesfowler7065 Год назад

Where did you find a 3.75 stroke crank? I wondered if someone made one because someone might not want a 4in stroke.

@markshaw3219 Год назад

I'm with you James. I'd like to know if this was a "in-house" crank or special ordered deal..?? That bore/stroke combination works really well in the first gen small block chevys.

@@chrisferguson1911 I built that combo. I called it a 349 ‘cause it has a nicer ring to it. Used a 6.2 Escalade block bored .060” over.

What’s the largest stroke crankshaft that can go in a LS block?

@p.b.sHUNTING Год назад

What does it cost to take a standard block and get it ready for rotating assembly.

@421ssrida Год назад

Depends on where the block is going for machining.

@joejoesmojo32 Год назад

Do forged rods with the 7/16" ARP 2000 bolts that come with a complete rotating assembly need resized? Or do those rods already spec out for the added torque to the caps?

so what is the difference between this build and a 416 ?

Hey Guys, speaking of doing it at home. Question, I see some build videos where guys are using assembly lubricant. I noticed you guys didn’t use or show you using it for the main cap bearings and rod caps. Is assembly lubricants not necessary or like there’s different schools of thought? Thanks for the response and content!

@baylymiley Год назад

Two things: 1. What tool do you put that chamfer on the caps with, diamond file? 2. When a used block comes in, for the piece of mind would you recommend always cutting it 5 over just to start with a brand new true round bore, or if it specs out, plateau hone it and send it?

@JacobVillemain Год назад

1. Yes, small handheld diamond file available in packs of 10 on amazon. 2. I always take a block .005" over. I've never seen one that didn't have .002-.003" taper

@TheKent99 Год назад

I don't understand why the 3.75" stroke was chosen. Even if you're not after max power, you're still giving up torque (and power) across the entire RPM range.

@JacobVillemain Год назад

different strokes for different folks

@brianshobert1124 Год назад

Longevity. Shorter rod,side loading on the cylinder walls, less dwell time at TDC, faste r piston speed all come with longer stroke.

@TheKent99 Год назад

So does more displacement, more torque, smaller dish/chamber for a given CR, and a lower RPM requirement for the same power.

@nicefknmodel2201 Год назад

Couple of questions. How much power would that ballpark? And what's that service cost?

@JacobVillemain Год назад

No service, 550hp
