[John Lang]

A friend has a 66 Bel Air 2dr post in real nice shape ,and he's talking about stock elim ! He also has a couple of 427's that he would like to have built for the car ! The car will be an automatic !
Does he have to run a 12 bolt, or could he use a Dana S-60 ! I did'nt know if he could , as i'm a Mopar person ! Where would this fit as far as Class ? Thanks for the help,,,,,,,,,,,John

John....a 12 bolt is all he can use that has any strength and the 427/425 HP engine is a 4 speed only combo for 1966. The automatic wasnt used until 1969 behind a 427/425. The 396/325 can use an automatic (400 or 350 Turbo) or a 4 speed. As a S/S car he could use the Dana 60 or a Ford 9 inch..

Yes....there is a 427/390 HP factored (derated) to 371 HP. It has oval port heads, smaller cam, cast iron intake, and uses a Q-jet carb.

X- Tech Man,,,,,,, Do you have any idea where a person would figure the weight of a BARGE like this, to see what class it would fit in ?
Anybody know about the engine combination, as far as the cam , etc, could it be competitive ?,,,,,,,,Thanks again ! Later ,,,,,,,,,,, John

It falls at 10.18 with a turbo automatic. Thats E/SA. multiply 10 X 371 HP for 3710 lbs then add the 170 lbs for the driver. It can run D, E, F. The weight I gave you is for E. I have the engine specs and you can find them on the NHRA site under blueprint specs. I will be home later and if you cant find them I will give the engine specs to you around 7:30 PM EST.

John the 427 390 HP is rated at 10.25 comp. with 96.4 c.c. oval port heads. It uses a Q Jet Carb and has a cast iron intake manifold. Not sure of the number as its not listed on my specs. (Might be the same as a 396/325 HP engine?) The bore is 4.250 and the stroke is 3.766. It has .008 deck and a dome piston of .140 thou. The legal piston numbers can be found on the NHRA piston list. The intake valve is 2.07 and the exhaust is 1.725. The cam lift is .462 intake and .480 exhaust. It uses an outer spring with dampner. Head gasket is .028 and the 7 different allowed head casting numbers are as follows.......702, 390, 802, 215, 063, 280, and 290. These are the last 3 numbers for each. Hope this helps.

Many moons ago, I had one with a 283/220 horse PG combibation.It had a 12 bolt, and went into P/SA and with the 220 horse factor x 16 pounds +170 for driver's weight,it weighed in at 3690 minimum. It ran a 6.14 gear and I left at 4000 against the converter,shifted at 7400 and went through the lights at 7800 at 98 miles per. Never blew that thing up, what with cast Badger pistons and stock valves and all, but if it would have broken the engine in the lights, the destruction would have been complete. A 66 Chevelle station wagon was an easier car for that class. The 427/390 with the automatic sounds neat, however.
