u can listen to the engine
it now has a 305
by the dispacement
A pineapple grenade because you are about to mess up the 88 truck has a weak motor prob don't have as much power as the 305 vortec don't do it get computer and motor from a vortec to put in the truck
the 1986 Chevy truck 305 HO produced 180 hp
The 5.0 is also the 305. So it originally came with the 305.
The motor site is a 5.7 litre 305 8 cylender engine.
350 or 305 depending on rear end
They are basically the same heads, If the 93 350 is a vortex motor.
The intake valve is bigger.
Depending on the year 87 and up is in the tank Depending on the year 87 and up is in the tank
The bolt holes are in the same place, but the larger combustion chambers and big valves would probably make the 305 run like crap.
Physically it is pretty easy to do, unbolt the block from the frame and lift it out and I think that the flywheel is the same size in both. The problem comes when you get to the electronics. The computer in the car will have difficulty operating the new motor. Unless the 305 has died its really not worth it to replace the block.
