hasselbach said:Having street and NHRA raced for about 30 years (and yes, I have seen some fast Buicks in the past), I seriouslly doubt you are breaking into the 11's with "street" tires (not M&H or other so called wrinkle walled dot's). The fastest 70 and 71's will do in the mid 12's on actual street tires.
With so much experience it would seem you would be familiar with the FAST series. It requires cars to appear stock, including cast exhaust manifolds, and run stock size bias ply tires. Those cars run in the 11's all the time and one recently ran a 10. 90. I run BFG drag radials, on the street and on the track.
An oval port headed chevy will out run a Buick anytime on Torque. The Buick heads sign off at about 4500 rpm (extremely restrictive intake runner design).
I would have also assumed you knew about head porting and how it can correct for stock deficiencies. Beyond that there are several very good flowing aluminum heads for the Buick.
As far at the porsche, HP means nothing. We've built some small 302 chevies in the past that made over 800 hp naturally aspirated, yet was all in the 8000 rpm plus range, with absolutely no torque down low. That's why your porsche is shifting so much, as the power is all upstairs not down low.
Thats great power, now make it last on the road for 250k miles and make it meet emissions and just try to make a 800hp 302 drivable.
Good to know I was speaking with such an expert.
