I didn't really know where else to post this. I have an 87 V10 with the manual 4 speed. I have a couple of the later years throttle bodys as spares/parts. The throttle body on my truck has never been rebuilt to my knowledge. I'm thinking of rebuilding one of my spares. My only question is will the newer style work properly. The only difference I can find is that Throttle Position Sensor is a different style. If I change the Pig tail over too does anyone know if the ECM will read it correctly? Any help appreciated.

Hey this is my first post, I have a 1987 Gmc v10 with the 350 tbi (2.02 heads mild hydraulic  comp cam, dual plane intake) i was driving and when i stopped at a red light and applied throttle it started to knock bad almost like itís detonating so i went home and did the usual when that happens change fuel filters flush the tank new fuel in with conditioner, make sure all the spark plugs have good spark change the coil and reset the timing to 0* the factory spec, i did all this and itís still doing it so i made sure all the valves and rockers were in spec and it doesnít have lifter tick so thatís fine but it starts great, and drives fine until itís above 1800 rpm under load or you stomp on it so iím lost what it could be any one have any ideas much appreciated?

I am upgrading my truck from a 454 to a 5.3l LS, it has a skyjacker 6 inch lift and rancho shocks all around with dual shocks up front. Itís a very firm suspension even when the 454 was in it now that Iím putting the lighter 5.3 in it could I possibly remove 2 springs from each pack to lessen the stiffness?
