I have a chevy van with a blown 305.  It's out and stripped and ready
for the shop.
It is a 2 bolt w/ throttle body and a "computer".

I'm considering putting a 350 in with a "RV" type cam in it so I can
pull a trailer.

Will I have problems with the "computer"

Will someone who knows about this please expound on it for me.
I need to make a decision about which way to go.

Thanks
