I am putting some new life into my current build. Its a 79 TA, 455, XE274, 3.23, performer intake, 6X heads, T-350 trans.
Currently, the car runs 13.6 at 101 in street tires. I am having the heads ported by KRE and am swapping in a 2.64 iron case ST-10 for the T-350. I run a REALLY tall tire on the street 255 x 70, because basically, I can't get any traction with a smaller tire. I have calculated that with this tire size, with my new ST-10, I will cross the 1/4 at the top of third gear at 5100 rpm. Would I be better off buying a smaller tire (26 inch) and crossing the line at say 4200... in 4th gear(extra shift) or am I better off saving a shift and coming in at the top of third gear? Ideas? Thanks. |

Sorry for the double posting, my browser locked up and I thought the first attempt failed.

Yea, you will be smarter, better, and quicker to use the 26" tire with the 3.23 gearset.
Get an electric pusher fuel pump in that chassis. 4800 through the traps...and you may be DEEP into the 12's. See signature. "11.00/123MPH/1.50 60foot/29.5"/4.10:1/10"/472 #48/Flat HYD/DualQuad/Wenzler/3250Lbs 12.00/112MPH/1.61 60foot/26"/3.31:1/10"/472 #48/FlatHYD/Q-Jet/Torker/3650Lbs"

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
