Here's my time for my 89 burb, on a fairly flat grade stopped in the middle of the road.
Stock coil, stock base timing, stock 12psi fuel pressure. 31" tire, 4.10 rear gear, 700r4.
Back on the old "pre engine bay fire" setup, I had an aftermarket coil and ignition system and a couple degrees put into the base timing.
Manually shifting it on this pull, I could hear the current stock coil fading at 4k, which the cam is practically flat at 4500, so I couldn't squeeze out a whole lot more.
This isnt a race truck... so I don't like beating on it too hard.
But.... I'll post a 2nd time after I turn the regulator up to 18psi to support the full 330hp + timing advanced+ better coil, and I'm confident it'll shave seconds off.
I would've ran it to 100mph, but the road was kinda busy , and thats dangerous at this time.
