Alright, I just acquired a 1973 350 small block that I intend to make a 396 stroker out of. My question this time is: will the accessories from my '92 engine bolt up to the '73 block? I believe I read that something to do with the accessories changed around '75 or '76. I ran a search and all I found was info on LT1 and LS1 swaps. Thanks for any help.

 

Yes, the accessories will bolt up - I bolted the acc. from my 1992 to a 1969 350 block with mid-70's heads with no problems. You just need to make sure you have the same acc. holes in the heads, then your brackets will all bolt up just as they were..

 

 

if not you can drill the holes and tap them, just make sure you use non hardening sealant on your bolts and you will be golden!

 

Yeah I figured if worst came to worst I could just tap them. Thanks again.

 

Quality control of factory castings was very poor in the 70's. I'd have that block very carefully checked before having any machine work done - sonic check the cylinder walls for thickness and core shift; starter bolt holes were often mislocated; lifter bores not properly aligned - the list of problems is long and distinguished.

If this is a factory 4-bolt main block, I would not consider using it for a big stroker. The main webs are weakened by the outer bolts, so only splayed 4-bolt mains should be considered.

It would make more sense to start with a 4.125" bore Motown block that doesn't have any of these issues.

 

This has been brought up before. And the fact is I just don't have $1,900 to drop into a block alone. And I'm not going for the 396 anymore by the way. A 383 should do just fine, and probably cost a bit less.

 

383 is probably a better idea.

 

that is something that i got to admit chevys motors are all pretty much interchangeable
