305 to 350

I am switching a 350 in and taking my 305 out. Is all that needs to be switched out in the computer PROM??

The only difference I know about between the two engines is the exhaust manifold bolt hole at rear of pass. side.

Don't know about this on Chevy trucks though.

Yes replace the prom. The injectors are the same as is most everything else!
