Currently refreshing the valvetrain @ 112k miles, 60k of that is with the heads/cam. Ran the times in the sig with that combo.
Currently adding a Meziere, new valvesprings, 1.6 rockers, 255 Walbro, 30lb injectors, extensive dyno tuning and a 12 bolt. Shooting for close to 400rwhp and high elevens this spring.
It's just getting broke in IMO.
Mobil 1 synthetics RULE,,, almost NO bore wear and I can still see hatch marks.

I have a 1994 Trans AM with 145,000 miles on the motor. My main mods are PCMFORLESS.com tune, 3" cutout, morso cold air, and Nitto 555R Drag Radials. My rear end is stock, my tranny is stock, my engine is stock (stock rockers, stock cam) (valve covers and intake have NEVER been off), stock manifolds, stock exhaust except for the 3" cutout and a flowmaster muffler.
My recent best was a 8.42@81 MPH in the 1/8th mile and a 13.30@101 MPH in the quarter mile. I usually have a 1.8 60ft time on my nittos.
whats everyone else running? I don't see many high mileage Lt1's at the track that run on motor.

I bracket race my car every weekend. 132k miles, CAI, BBK, Underdrive Pulley, CSI, Flowmaster, MSD 6A, PCMForless, 3.73, ET Streets on Welds, SFC, LCA, 13.28 @ 105 best.
I'm not sure what converter it has, but I am almost positive that's why my times are relatively slow.
Car is fun to drive and very consistent at the track. It's not my daily driver, but I drive it everywhere but to work.
