Previous 400:
#13 heads, mildly ported (maybe 230 cfm) +.030" with TRW slugs shortblock, stock rods, ARP bolts, zero decked. Comp XE274 cam, Comp Magnum 1.5 rockers. HEI distributor. Performer intake, cut down under secondaries, 800 Q-jet. HO Tri-Y headers, 2.5" Flowmaster exhaust. Installed in 3840 lb race weight '72 Formula with 3.23 gears and Coan 3000 stall 11" converter. Performance: 13.60s @ 101-102 with 1.9 60' on street tires. Engine had internal problems and self destructed before I got it fully wrung out. Next 400: #061 heads, ported by Dave Bisschop, flow 270/195 cfm, exhaust crossovers filled. +.030" block, TRW pistons, stock rods beam polished, ARP bolts, zero or +.005" deck height. Old Crane solid roller 232/244 @ .050", 113 LSA/109 ICL, .335" lobe lift - roller version of RAIV. HS 1.72 rockers, .560" lift at valve after lash. HEI distributor/Crane HI-6 (rev limiter set to 6200) Holley Street Dominator intake, port matched, plenum ported, water crossover separated, exhaust crossover removed. Various spacers will be tried. 800 CFM Q-jet by Cliff. Will also try Holley 850 DP. Holley Super Comp headers to 3" exhaust with X-pipe & Dynomax Ultraflows. I'm building this combo because I have all the parts except rings & bearings on hand and I'm too poor to buy new parts right now (like rods & a more modern cam design). Going into my '73 4-speed 'bird with 3.73 rear gears. This car is going on a serious diet, hope to get weight under 3400 lbs with me in it. Expected performance - ???? Hoping for mid 12s on street tires.

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.
