Just as the post states, what are the differences between the 305 TBI's found in trucks and the ones found in f-cars. I know practically all the differences between the LO3 and the 350 TBI but not the non roller 305 version in the trucks.

The truck is a 92 by the way.

Heres what I know
Non roller block and cam
Same intake and TBI unit as on f-bodies

What I don't know as compaired to the LO3
Do they have the same heads and CR?
Are the cam specs the same?
Are the stock BIN's similar?
Does it have the same ecm as the truck 350TBI or as the f-body?
Power output?
Larger injectors (I know the 350 TBI does but does the 305?)

I geuss I should ask what they share in common tech wise, besides the affore mentioned stuff that I already know.

 

I would think that the truck would use the 7747 ECU with a different PROM chip. I think the only vehicles that GM made with the 8746 ECU (or what ever the number is) are the Camaro, Firebird, TA(samething), and the caprice. The cars seem to get an inlet air temp sensor and probably a different spark curve fro the lighter vehicles. Someone correct me if I am wrong.

 

I'm pretty sure the cam specs, cr, injectors, and throttle body are the same. I know both engines are rated at the same 170 hp, which would lead me to believe there has to be some other differences as the roller cam should atleast give the camaro L03 another 5-10 hp.
