Ive been looking to build an engine this winter for my 82 cutlass to replace the 267 and I could really use some help getting the Olds and Chev small block thing straightened out.
Some sources online claim differences in trans bolt patterns, motor mounts, alternators and a few other bolt on components. Other sources claim they are all there own engines completely separate and non compatible between, some sources claim Chev, Olds, Buick, Cadillac etc also used the same engines cross each platform on occasion. This was specific to the 350, 443, 455 engines. I couldn't find anything on 267 or 305's but a bit on olds 307's.
I thought a trip to the local PNP would set this straight in my head. Well from what I can see the 305 Olds and Chev look damn near identical, were these a cross platform engine? There's a nice looking 305 in an 84 cutlass brougham that looks promising, all the 305 / 350's from the Chev's are half stripped and exposed. There's also a f body Firebird with standard trans Id like to take but the 302 is junk. Any chance these would bolt up together?
The other big mystery is this 267 I almost can't see Chev and Olds making the same mistake and both building there own versions of this abomination. would this be the same engine or trans. bolt pattern between a Chev 267 and Olds 267? more specifically if it is the same engine who's bolt pattern is it, the Chev or the Olds bellhousing?
Id bought this car thinking a small block was a small block after Ive been collecting SBC parts here and there for the last decade. Thanks for any help links or advice getting this confusion straightened out.
