How to tell if its a 350?
Dont blast me for not searching cause I did. I have a 89 rs with a 305 tbi. I just bought another one for real cheap that I have no info on what so ever. Was left behind at a rental. I do know its a 89 rs tbi with t tops, & it has center bolt valve covers. What code would be stamped on the motor if its a 350?

On the side of the block will be cast 5.7L
Get the casting number off the block. Since a 305 and 350 have different bore sizes, a simple casting number will be the easiest way to tell if it's a 305 or a 350.

yeah.....no tbi motors were 350's....only tpi. and not many of those....sometime you can tell by factory badges...if it says tuned port injection, it's a 5.0...if it says 5.7 tuned port injection, then of course it's a 5.7. Also you can check by the vin number..but best way if of course to check the block numbers it self..also if it came with a factory 5-speed..then it is also only a 305...

Google? Just go to the TGO home page and read through the tech data.
According to the tech data, an 89 RS with a V8 will be a 305 with a TBI. In 89, the 350 wasn't offered to the RS and the 350 had TPI.
