Gonzo is right on saying that 12.9-13.1 for RA4 A bodies is right. I had planned on certifying my 69 RA4 GTO,but did not get it done until Tues before the race. This car is done to nhra spec,absolutely zero porting,and a factory camshaft,not a nhra legal cam,but a factory cam(DOG BELOW 3000 RPM),best et first time out13.11 at 111.00.This is what a nhra blueprinted 4 will go with a 4-speed.Not nearly as quick as LS-6.I think that an automatic could run 12.7,s in pure stock condition in a GTO. Mino has consistantly always ran good when the Chevs were not.Bottom line is that the Pontiacs with a RA 4 will run almost dead even with an LS-6,Which was rated 80 horsepower stronger,and had 54 cubic inches more!!!Why couldn,t Pontiac have built a 455 cid,11.1,Ram Air 4 engine in a 70 GTO????? That would have been sweet!

Sorry Mike,I forgot to mention that he put on 9 inch goodyear slicks. [d-5]compound! The logbook the guy kept on the car was incredible. He monitered everything from barometric pressure to the heat of the track every time he went out! Airbags in the rear springs [8lbs on the left 15lbs on the right].LAUNCHED IT AT 6000 AND SHIFTED IT AT 6400 BECAUSE HE SAID IT MADE NO MORE HORSEPOWER AFTER THAT] AND THE CAR STILL HAS THE ORIGINAL BLOCK IN IT TODAY. The car ran a miserable 1480's on the polyglas tires.
