Found and olds rocket motor.. now i have went through all the archives and previous posts and cant find the block number its 574534-4 CFD The heads are 571870 #16 some sites say its a 57 371 some say its a 58 371..
Are those the cast numbers? does it have a stamped number on the block? did they ever sell Oldsmobiles in Canada?
Chad, I'm around the corner from you in Kitchener. Not sure on the later 371s and 394s, as I into the 303's and 324's but here's a bump. @Paul or @GOATROPER02 should be able to help you out.
Yep the numbers is cast into the belhousing...cant see any numbers stamped on the block on the passenger side ?......yep sold lots of olds up here....lol
'58 stamped number is on pad above center exhaust port on passenger side and starts with the letter "B"
My buddy just sent me that pic. Seems i over looked the 4 1/8 . i am gonna assume its a 394. With maybe some 371 heads by the looks of it ?
looks like a '63 394 block were the #16 heads bolted to that block? didn't know that was possible with the push rod spacing..
