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?

Recently installed used radio. All works except when radio is on when key off,  radio is not on when key on. I could not use the OE power connector, so connected power wire to newer connector. When key on, have to turn radio off then on and works. This is the second radio since purchase and did not have this with the previous install. Kind of confusing but am still able to use radio.

Any ideas?

Oh man, got in a little too deep and too much time away from my rebuild.  I have my '84 C20 which I converted to 4WD, crew cab, long bed, but working on putting the engine back in (454) and having some issues ever since I went to an electric water pump.  I need help ID 2 brackets.  I was able to buy a special bracket for my alternator, but now having issues mounting my PS pump, which may need a special bracket, and hoping someone has some stock photos, so I can try and understand what I am missing..... The 2 brackets I think are either for the AC compressor or somehow the PS....., I show front and back sides of them.  (Scratching my head......)
