Building a 408 stroker, need advice
Building a 408 stroker, need advice Like it says, I'm building a 408 and I will top it off with the L92/L76 combo. I will be assembling the motor. What I need is some sort of reference material for clearances, torque specs and what not. Is there a good book out there that will have all the nice to have don't forget to do this and check that information. I've looked but keep coming up empty.
Unless you have a full machine shop available to deck the block, align bore the mains, properly hone the cylinders, etc then you're doing you and your engine a disservice. Putting a short block together is not brain surgery, but doing it right is another thing. My advice if you have already got all your parts together, is to ship them to Erik @ HK Enterprises a sponsor. The guy just built a 408 for me and two of my friends. Erik is so meticulous and into detail. Plus he's just plain engine smart.
Yes, I am having all the machine work and balancing done by a reputable shop. I want to assemble the motor. I just need to know if there is an assembly manual with all the information I need like stated above.
Scoggin Dickey, a sponsor, or any Chevy dealer can get you the engine build manual. The problem is that it is based on an OEM build. Using ARP bolts changes the torque specs FWIW. Ring end gaps will vary depending on whether you use nitrous and how big a shot. So as good as the GM manual is it won't tell you all you need to know using aftermarket parts.

I agree! Erik built my 408 and he is awsome to work with. Very good to talk with and helps in anyway! And, just builds one sweet motor!!

There is an excellent book by Will Handzel "How to Build High-Performance Chevy LS1/LS6 V-8S" That will tell you about everything you need to know.
From a few that I have built and re-built, I can tell you the most important, rod clearances same as small blocks around .0025. Mains on an aluminum block, that's a different story, under .002.
Cam bearings, under .003

It's true that is an excellent book, I have it. The problem is that a lot of the material is dated. Much of the text refering to mods, and the companies that have those available is passe. Up to date info is definitely lacking.
