Truck motors?

I've seen what looks like pretty good deals on the v8's that came with the full size blazer's/pickups that are 350's (tpi's i presume). outside of suspension/drivetrain/rear axle issues, what (if any) would have to be done to them to configure them for a 91 camaro convertible with a v6 currently under the hood?

i looked under the sticky regarding the swap from a 6 to a 8 and nothing was mentioned about the truck motors.

Re: Truck motors?

Depends exactly what motor it is. Original SBC similar to a third gen is a normally a straight forward direct swap. LT1 is relatively easy. LS engines take a bit more work to swap over.

The only difference between a car and truck engine may be the oil pan design. Trucks may also have a different cam grind designed to make low end torque required for trucks.

Re: Truck motors?

Trucks never came with TPI. Starting with '87, they did get TBI, but the 193 heads are for low-rpm TQ. '87-up blocks are preferred, because they make it cheap to go with roller lifters. Considering where you're starting at, your dream find would be a '96-up Vortec 350, the RPO code is L31.
