It took raising my shift point and uncapping the exahust to do it, but I have 3 time slips that read 12.9x. The weather was just about perfect - mid 60s, sunny, and low humidity (I'll post the DA if I can find it). I'm still running the same tune that I did last May so I'm sure that there's more in it. I have a wideband that I'll be installing this winter so next spring I'll be able to nail the perfect tune. My goal was to run 12s on the horrible 255/60-15 Firestone Firehawks, so traction is the obvious limitation. The track was preped pretty well because I never could get my 60s under 2.2 until yesterday. Car plus driver is approximately 3300#.

So, here's the slip:
RT: .1548
60': 2.0931
330': 5.575
1/8: 8.3992
1/8: 87.18mph
1000': 10.828
1/4: 12.9023
1/4: 108.67mph

Just thought I'd share my joy with you all.

Oh man, I read your post, I had the same tires on a CRX si, bought them for my brother he was short on cash, long story short I think we had 55K on the tires they are ROCK hard, after all those miles I still think there was 1/4 to1/2 inch of tread left, what mods have you done, I'm doing the same you are LS1 to a 68 camaro, how did you do your fuel system, Steve

 

How do you like your 224 cam? Does it have a nice sounding idle or stockish?How was tuneing?
Thanks, Ken

Steve: It's impossible to find decent tires for 15" wheels anymore. Click the first link in my sig and then click "LS1 SWAP". There's a page on there with info for each system of the car.

The motor is stock 2000 F-body LS1, except for the TR224 cam. I like the cam a lot. No, it doesn't sound stock. Tuning it was not hard at all.

Pat: Good to see you around here. Drop me a PM and let me know how your swap is going.

 

What track? Lapeer? I want to get out soon if all goes well. good job! I'm in Orion

Cool, I'll have to check it out, whats the specs on the cam??

 

TR224/224-112 Thunder Racing Custom Camshaft - 224/224 .563/.563 112 LSA 1700-6600 RPM Power Band. Excellent mid-range & high RPM power. Requires computer tuning on automatic transmission cars. Due to the fast ramp rate of this camshaft, the use of 1.8 rockers is not recommended.

 

I will try lapper in the spring.. happy racing!

 

What is the DA of the track.

I was at 5200ish and ran a 12.9@110 on a very shitty preped track (lost traction in 2nd gear on all runs and had to cut a few short b/c of it) after my cam. 2.15 60'

Before the cam i ran a 12.5@113 down in Houston. 2.01 60'

Your right, there are no good street tires for 15s.
All my runs were made on 275/60-15 BFG Radial TAs

 

DA was about 1265. The lack of headers is really holding me back. Well, that and the LS1 heads. I really should have had some work done to them when the motor was apart.

Back in the day when I had my '79 T/A I used the McCreery 255/60/15 drag radial (dirt compound) . They hooked great at the track . The motor was an OLDS 408 ( torque monster from Dave Smith OLDS) . I had a 700R4 , 3:73's and the thing could pull a house down ( peak torque was 2400 rpm) but couldn't pull on the big end of the track. I would pull 1.90's all day long for a 3700 lb car was pretty good. My best ET was 13.40 @ 103.9 mph. And that engine had a baby 214 cam. I don't know if they make those anymore but next to a full slick tire you couldn't do better (atleast back then).

Awesome! Congrats!!!

 

is the cam pretty aggresive sounding or just have a slight lope???

 

It all depends on your exhaust and where idle is set.
