lt1 power

I have a 94 trans am stock bottom end LT1 with ported stock heads and intake, cc306, 3600 stall, 3.73 gears full bolt ons 3550 raceweight. Last Saturday ran 1.60 60 ft 7.24 @ 95 1/8 mile and 11.35 @ 121 1/4 mile.

Thanks. I am happy with it runs great for what it is. And for SHOWNOMERCY, sorry my stock bottom end car is faster than your supercharged 383 stroker, keep your jealousy to yourself if you don't have and anything to say related to the post.

Supercharged...? I think you have me mistaken.

That's decent. Who ported the heads?

lt1 power

Not sure bout the heads it was done by a professional machine shop, bought the heads second hand off of ebay for 400 bucks. stock size valves, heads comparable to le1 maybe. Eric Bradby with E.b. Porting is just up the road from me, he ported Joe Overton and Mike Actons heads local lt1 guys running 9s and 10s on motor. I would like to take the heads off this winter and let him work some magic on them.

If your stock-bottom end N/A car is trapping 121 mph at full weight through an automatic, the heads don't need any more "magic" worked on them.

The heads are very mild maybe 180 to 185 cc. Its normally traps 118-119 mph 11.5-11.6 et in warmer weather, this cold weather and low DA, is whats helping it run so much better.

I agree. Unless you're chasing some kind of record, leave it as is and enjoy it!

My goal is to get 10.90s with the setup, with some weight reduction and suspension upgrades. Racing this Saturday, will be about 100lbs lighter than 11.35 pass and did some rear suspension changes. should run 11.1-11.2 this Saturday. I will post update after I run it.

Were you spinning with the 1.60 60's?
If not, then suspension changes won't affect it.
It will take sub 1.50 60's to run a 10.9X. I suspect it won't happen with that TC and cam combo, ....unless you REALLY lighten it!

lt1 power

Not spinning but I have stock shocks and springs with nearly 200k miles on them, I bought some 50/50 drag shocks and an air bag for the right rear spring. Hoping for at least mid 1.5 60ft. I have the mph for low lows 11's now . Next year after tax money I want to get some Qa1s for up front that should help my 60s considerably.

Not trying to discourage you from making those mods, but as I said, if you're not spinning now, that 1.60 is more or less where it will stay. You may gain a couple of hundredths by eliminating some deflections here and there.
The mods WILL help you if you decide to bump the stall. If you really want 10's, then I think at least a 4000 stall is in order. Not just for the launch, but to keep the motor in its powerband after each shift. My motor combo has more low end grunt than yours and it wants every bit of the 4200 stall it has. Best NA 60's have been 1.43; the 10.98 was a 1.48 60'.

What track are you running?

lt1 power

Wow that's impressive if I had the money I would go with your same package AI 200 cc and the 22x 23x duration 60x 60x lift. That would work great with my combo as the fastest f-body stock bottom end has the same package and he runs 3600 stall and 3.73 gears also.

Running @ Richmond Dragway, VA

Nice times. Your car is similar to mines.. I run a 11.37 @119 1.53 60ft.. I'm pretty sure it would have went faster if the 2-3 shift didn't hit the limiter.. I have 180cc heads 230/236 cam.. 4000 stall.. Do you mine posting the slips?

Wheel Stander

Ignore the naysayers ... your car is plenty quick for what you've done with it. My C4 LT-1 is in the process of getting a top-to-bottom rebuild to 383. If it ends up running 11.30s, I'll be VERY pleased.

What rpm are you shifting at and how long have you been running that rpm on the stock bottom end? I'm curious to see how long it lasts, a lot of people get scared of running over 6000 on the stock bottom end, its good to see good times with a big cam like that on a stock bottom end. I don't know about the "fastest cc306" thing, dissecting it down that far is like "fastest white interior car". I do know chas010 went 10.98 at 122 on a cc503 and stock bottom end https://ls1tech.com/forums/lt1-lt4-m...nto-10s-5.html , he did 7.0s in the 1/8th to your 7.2s.
