My Setups...
'82 Camaro Berlinetta, V6 to '86 LG4/TH700. Engine mods include World Products S/R Torquer 305 heads that I ported, Crane 2050 Compucam, Hooker 2055 headers, 3" exhaust to an 80 series Flowmaster, all emissions-legal in Colorado. Tranny has a restalled to 2300 converter, Transgo shift modifications (Vette servo, .5 valve, etc.). 2.93 posi, 16" Z rims w/GS-C skins. Runs 15.7's here at altitude, tranny has a 2-3 shift at WOT "issue", so it was beyond the shift point in 2nd at about 1200' - with properly shifting tranny, would probably have been better. Translates to about a 14.7 at sea level. In the works is a ZZ3 shortblock that has been bored .030" over, Speedpro hypers w/slight dish (10cc total), ARP rod bolts, ZZ4 cam, to go with the rest of the combo already in the car. This year is the last time it needs an emissions test, so I'll probably get it tested b/4 the 350 goes in, and "forget" to put a few pieces back on.
My "other" car is my first car - 1957 Chevy Bel Air, which I've had since late 1971. Currently has a 396/TH400 from a '66 Impala, I've gone though it with forged TRW pistons (at least it was TRW when I did this in 1997), ported heads with stock 2.06/1.72 valves, General Kenetics 270 cam. The tranny has a TCI shift kit, ACC Boss Hog converter that stalls around 3500 (they call it 2800-3200). 3.73 8.2" 10-bolt & Powertrax, Hoosier 26x9.5x14 Quicktime Pro DOTs. With me in it, weighs about 3850 lbs. Best of 13.77 @ 97.1 at altitude; 12.94 at Topeka (on a run in which I lifted) at around 103 mph.
A lot of people run faster, a lot of people have better rides. All I can say is I'm the 2004 NHRA Div 5 Summit ET Sportsman champ and National runner-up with what I brung. I don't know it all, but I usually know when I'm over my head and I'm willing to learn!
