i am looking to rebuild an Gen I 350 or 305 most likely an 350.
i have never done this and i was wondering who makes the best replacement or stoker Cranks, and also who makes the best Cams?
not 100% sure on this i know about pistons, and carbs because its either holly or Edelbrock. and i know ever one says holly not sure why.
Thank you in advance

The best cranks are probably Oliver (same for the rods). Diamond and Mahle are probably your best piston makers. Best cams are going to be custom, probably want to look up Jones Cam Designs in NC. You'll probably want to go custom on the carb as well. If you're thowing the best of everything at it no reason to skimp on the carb.

Ryan, please define what is best? Best available or combo to resonable cost? Also what is the planned use; street or race?
Tip: include cylinder heads, headers and exhaust as well.
ok being its going to be while before i get the engine being its realy muddy where its at IE in an junkyard its in an storage thing so it don't get wet and stuff and seize up.
i do know now its an 350 Cid its from an car or truck the guy at the junk yard didn't remember witch off hand. i do know it had an Carb on it.
i will post more on the engine in an separate thred later when i get more info on the engine
but as for cams im looking for Street ie good gas millage and good power maybe more on the low end. and by good i am referring to not an cam that is going to crab out really quick
its probably going to go into an Camaro, Chevell, or maybe an C3 vette it depends on what i can get my hands on
as for the crank its more for replacement for this engine that is if it needs one. im getting into building engines and stuff, and this is my project engine.
thank your to all who have posed

While thinking about which engine to build, it might be an idea to download CamQuest6. You can play with it and see what brings with differnt configurations of engines. The program is somewhat limited, but for most of us give fair indication what's all about....
thanks looks like an good tool to have. will help with figureing out what cams an stuff will not work right for the engine.
now as for replacement Cranks who has the best ones ie ones that have the best quality.
im curious but how hard would it be to put an 3.75 in crank in it?
just an question for future rebuilds but is there an 4.00 in crank out there for the Chevy small block Gen I? i think i remember seeing it an while ago but i don't remember where

If your going to build a stroker have the block sonic tested before you do any work to it!!!!!!!!!!!!
A 4.000 crank requires a lot of work and by time you grind the crap out of the pan rails and bottom of the cylinders it does make the block weaker and with the small base circle it looks more like a pencil.
For the money the Callies Compstar is the way to go as the journals are round, flat and the cranks are straight.
Depending on the rods you use the pan rails may require some grinding.
I would recommend the either the Callies Compstar 6 inch rod or the Scat Procomp rod with 7/16 block as both rods have alot of block and cam clearance, And even with thses rods we have our cams cut on a 1.130 base circle which give us plenty of clearance and we don't spend extra timing moking up the build.
It depends on how much money you want to spend and what you want for quality as far as parts go.
The Mahle pistons with rings for 525.00 is a good choice for pistons.
yah the 4.000 inch crank would only go in an 400 Block being as i rember that it has an enlarged crank throw aria then the 350 block. but personally idk sounds like a little more work then i really want to mess with right now. most im looking at is an 3.75 in. Converted 400 crank to fit in the 2.45 inch journal blocks.
now being its kinda had me thinking for an while now but is the bottom end of an 305 about the same in terms of clearances and grind ability as an 350?
looking at an 383 maybe for the extra low end power.
would it be sane to take a 400 block and put in an 4.00 in crank to make an 427 or would that be more work than its worth ie would i be better off bugging the guy at the junk yard for his 60,000 mile 454 BBC that he has that runs?
my plans for the current engine is to rebuild it to either an stockish 350 or an 383. the 427 idea is more of an later project after i figure out how to rebuild an sbc better
im looking at is an 3.75 in. Converted 400 crank to fit in the 2.45 inch journal blocks.
Old skool way Nobody does that any more.
Plenty of quality off the shelf drop in cranks with 3.75 stroke. Scat , Eagle at cheaper end of market.Cast , cast steel , forged ; take your pick
A 383 will give you all the power you need if only looking for 5000rpm

yah i see that there are off the shelf 3.750 and now the GMPP 383's 3.800 Crank
yah 5,000 is about all i would want from an 383 being it would start pushing out an lot of power right from the low end anyway
if i wanted high end i would go with an 327 or a 372 (4.125x3.484)
