I just bought a mid 70's 350 truck block 4 bolts mains, .040" over with .040" over Speed Pro flat top hypereutectic pistons and rods and a crank that is has been 10 10 he said. What is 10 10? Does that mean the crank has been turned to use .010" oversize bearings? I only paid $500 for everything. My plans are to turn it into a 385 or whatever a 350 bored .040" over with a 400 crank will give you or I may just use the crank that came with it and make the 356 or 357. The block has been line bored as well. I think $500 is a good deal for a block, rods, pistons, crank and the machine work. My question is, is it necessary to always file your rings? How do you know when you need to? I imagine I need to buy rings for .040" pistons, right? Don't rings for .040" over pistons mean they shouldn't need filing? This will be my first complete engine build. I am doing this to teach my son and also to build a more powerful engine for my Camaro. I plan on using a retro roller cam and fuel injection just for the hell of it. I hope I will be able to rely on the guys here if I have any questions along the way?
Here is another question. Are the Speed Pro pistons good for a street motor? Also, will they be ok to run in a stroker motor? I am really thinking of making this a stroker. I may get a Scat stroker crank, but I have absolutely zero experience with strokers. I see 383 cranks, but this is bigger than a 383. Can I still use that crank even though the bore size is 4.060"? When they say 383 crank, do they just mean the stroke has gone from 3.480" to 3.750"? Also, with a flat top piston, if I trying to get a 10.5:1-11:1 out of this thing, what cc head do I run and what head gasket? I may just save the money it would cost for the stroker crank and use the crank I have and just make the 356 or 357. I can still get good power for a street car from a 356-357, right?
