Prefer to use a 350 block .030 over,not interested in finding a 327 block if I don't have to. I have the forged,small journal 283 crank with it's 3.00 stroke,5.7 in.rods. Can anyone tell me where to find pistons that will fit or would there be a different length rod to use that would make it easier to find pistons? Would prefer to use a hyperutectic slug if available.
You cannot use a 283 crankshaft in a 350 block as the mains are sized differently. You will have have your forged crankshaft journals built up by a place that builds stroker cranks. I know that Abraham's machine shop in Davenport, Iowa, could do it for you. But it would be a lot easier and more cost-effective to find a 327 block.
Lynn,there are companies that are making main journal spacers for them now.From what I have heard they work fine.
'67-'69 Chevy 302 pistons should work....

Thanks techinspector1. I figured those would work but what I don't know is if I use another year 350 block other than those years,are the block heights the same? Other words,are all 350 blocks the same measurement from crank centerline to the top of the cylinder? Was worried that I might wind up with a block cylinder that would be either shorter or taller than my 3" stroke with 5.7" rod and 302 piston???:eek:
Factory spec for all Small Block blocks is 9.025".
Piston manufacturers use a deck figure of 9.000".
You might indeed encounter a block with a different deck. That's why you hear about fellows milling the deck of the block to achieve the proper piston to head dimension (squish). Aftermarket pistons are usually shorter from the crown to the centerline of the pin to accomodate this milling and allow for it. That's why you must be extremely vigilant in measuring everything before assembly.
Thanks again techinspector1. That explains why some aftermarket economy pistons are sometimes a big disappointment,performance wise. Guess I'll need to try and match the 68-69 302 compression height and compression ratio then,but thats something the machine shop can work with in decking,and myself with head gasket and piston design.Thanks.
AAAANNNNDDDDD,,,,HAPPY BIRTHDAY!!! So good to know there are older and wiser minds here to give us 'kids' good hotrod info.,I'm only 52, still wet behind the ears.
go find a 327 ok. you stil only going to be pushing 302 even with a 350 block. man. .......................
gassersrule196, you'd do anything to talk me out of this motor?:cool: Hey,,,Spokane is to far to mail it and I can't seem to find envelopes that big:LOL: Seriously,why 327 now? The 350 will bore and accept any head. Reason for 302? Addicted to that high rpm action. First race car I ever drove was a 56 shevy,destroked 327,4 speed,12bolt,4:11 gears. That was almost 40 years ago and I still want to cry:CRY: cause dad sold it instead of letting me(16-17 yrs.old) have it.Said he didn't want to see me wrap it around a telephone pole:eek: .Poles-r-round,56's-r-square,,,I don't get it?lol**) Block,heads,intake will be on e-bay within 2 weeks.The block is the HB.:3dSMILE:
