Re: 1984 C10 BBC 427 feels like its lacking in its true performance abilities.

that's what we did geezer#99 and then we realized it was messed up somehow. so then we did it by ear, til the sweet spot was found. this engine has been in the truck since 1989, but only has had 15,000 miles put on it in almost 30 years.

I'm using Valvoline VR1 racing oil. oil change receipts go back to 1989 and it says valvoline so with the cam i figured having zinc was a good idea.

and yes I do have stock manifolds, but running stock width 2.5 inch exhaust, no cats and flowmaster chambered mufflers. so its not totally lacking flow but it would probably love a 3 inch exhaust for sure.

ill take care of the kickdown issue first then get a good shift kit, and have my shift points adjusted up a bit and then go from there.

I really can't afford to get an entire new exhaust made for the truck, its got a perfectly fine exhaust on it and it does sound pretty mean.
