403 Big block engine swap to a 350 board out 40 on an 87 Oldsmobile cutlass supreme
I have a 1987 Oldsmobile cutlass supreme
project car that came with a 403 big block
that has some issues I have a new board out
40 350 engine that I could swap out is it
worth it for more horsepower
This is the 403 with issues
This the new 350 big block
My mistake the 350 is not a big block obviously
it's a straightforward swap, you won't have any problem with it, it comes down to what you ultimately want, a running engine versus one with "issues". There's plenty of power in that 350 for your car.
The 87's never came with a 403. A 350 is a good choice.
The 403 was swap out not the original. I’m probably going to have to get a new tranny also. What’s your recommendation for that engine?
Thank you for all the quick help. Again this is my first project car and I’m just finding more and more issues(frame was cut to accommodate wheels, suspension is too tight..I can go on) but still want to put some time into it
Any recommendations on tranny?
