Important if you run D-H/S or SA

Before you worry to much about this combo, which there aren't that many out there, you might want to take a look at the 91 Corvette which holds the G/SA record at 10.54 at 124 or the 73 Pontiac TA - 455 at 306 hp. If you think all this aluminum stuff helps so much (other than weight) then why is the 70 Duster with aluminum heads 2 hp less than with cast iron heads? The AVS 340 combo & the 383 only take a 1 hp hit with aluminum heads & be prepared to spend big $$$$ to make them legal. Wish I could use a Quick fuel carb or a 4 speed auto trans. Didn't powerglide combo's got a 3 speed, why can't I run a 4 speed auto? That would help way more than a manifold. Can someone tell me, what is stock about stock eliminator these days. Just sayin.

G record is 10.57 not 10.54. However, it may be faster than that by the end of the year.

Sorry for the mistake, could not get the the NHRA national record page. On my best day I would never see those numbers in my car at F weight. I guess I got a lot of work to do.
