Page 3: Mods...bigger and better...
Being so close to that 12 second timeslip, I was itching for more mods over the winter. A set of 3.73 gears were installe... Show mored and I finished off the rearend with a T/A cover, ARP wheel studs, and had the axle tubes welded to the case. Before reinstalling the rearend I painted it black...no more ugly rusty 10 bolt. A spring cruise to the track netted a 13.21 @ 106...an overall gain of 2 tenths and 2 mph. The chrome ZR1s went on the car about this time...they were from my dad's '98 SS convert.
A friend of mine was doing a cam swap on his Camaro, so I wanted one too. My first cam was the Lingenfelter GT2-3. This stayed in the car for just less than a year.I took it out for a cam with more lope to it...something that wasnt so quiet. Cam-only with the GT2-3 gave me a 13.10 @ 107 with air temps in the high 70s and still on stock tires and not tuned.
Insert another winter here.
GT2-3 cam came out, Thunder Racing 224 cam went in. I was still using the Manley 1423 Springs with Ti retainers, and a Rollmaster double-roller timing chain which I installed with the first cam.
It was time for the stock exhaust manifolds to go bye-bye. A set of Jet-Hot long tube headers were next. It was harder removing the stock manifolds than it was putting these in. The Jet Hots fit better than I expected and damn they were pretty. I also put in a Hooker uncoated Y-pipe with no cats...and yes, the SES is on all the time now.
At the same time that I was installing the headers, I also decided to do a higher stall torque converter. I went with a Midwest 3500 stall with a 2.0 STR. To keep the trans cool I also put in a GM deep trans pan, a B&M 19,000GVW cooler, and an Autometer temp guage to monitor it all. What you may not notice from this pic is the stock shifter was shortened about 3/4"...much less stupid looking, to put it plainly.
This is just a shot of the clearance I have with the deep pan. Open headers are as loud as you might think they would be...don't ask me how I know.
The headers and the converter made a huge difference in performance. I decided to switch to a pair of Nitto Drag Radials (275/40/17) and it was time to get out to the dragstrip again... Show Less

A little weight transfer on the launc... Show moreh...but still far from getting that left front tire off the ground. Since it was a $20 event, they did not give us any VHT...about all we got was a quick sweep of the starting line. Sixty-foot times were 1.75-1.85s all day. This was my first time racing with the new cam, headers, and converter. I expected it would run 12.50s...the results were better than I expected.
Another race at the same event, this time next to a friend of mine with a green Firebird. He won with a 13.22 to my 13.23...needless to say we both spun bad! His best so far is a 12.05 @ 113...it's an automatic with a Vig3200 stall, cam, headers, Nittos, etc...
He is a launch pic from Rock Falls Raceway in Eau Claire, Wisconsin. Track prep was alright and my best 60' of the day was a 1.75 on a 12.34 @ 110.5 pass.
In the pits...looks like the Nittos are being irritated...I cant imagine why...
