i have a 88 l05 from a truck and was wondering if there was any info on this engine

the camshaft dosent look like a roller so can i use a regular cam to swap in

Swirl Port 350 should have TBI. Probably uses a flat tappet but may have provisions for a factory roller which would be a good choice for replacement of the existing cam given where ZDDP additives in oil is going (away).

It's not a particularly powerful engine 190-200 hp. Compression is low, cam beyond mild. The heads are Swirl Ports which for what you want is just what the Doctor ordered. You'll need an intake that adapts to those heads (different angle on the center bolts from 90 degrees to the head port face to 72 degrees). You could use an adapter to get a two barrel onto the existing manifold.

Compression is low but don't be tempted to mill the heads more than .030, modern thin wall casting just doesn't allow space to carve deep.

A cam with duration in the range of 190 to 210 degrees will really wake this motor up without surrendering the bottom end torque, this would prove to be helpful, especially if your plow truck has a stick gear box which makes keeping the engine in its best power range easier to do but will still benefit an automatic.

Ignition will need to be an older HEI as the distributor for this engine was probably dependent upon a computer for advance instructions. You'll need to add a timing tape to the damper so you can time the thing. Now it probably only has a TDC mark on there.

This engine uses a one piece rear seal, this requires a flex-plate or fly-wheel capable of using its 3 inch bolt circle and having a bit of external counter balance. Either of these will bolt to your existing torque converter or clutch depending on what's there.

The serpentine belt system uses a water pump and fan that turns reverse to what V-Belt engine's use, so either go with the serpentine that's there, or if going back to V-belts be aware that you need to ask for pre-1986 parts.
