Bob, 383 ,with 45 horsepower off it.
That'll fix just about anything.

WOW.....ALL I CAN SAY IS WOW...

750 CFM AFB
10.0 : 1 compression
203cc Intake runner


280HP with a stock head
285HP with an Edelbrock Aluminum Head


WOW...

[GTX JOHN]

I Think the AFB 0n 383/426 in 66 is around 600 CFM ( maybe a bit less than that) I own one and it is small.

This engine has some things working against it. The carb on my bench flows 566 CFM, the near 0 deck height and .020" gasket combined with a small block like stroke make any cam with even modest duration difficult to fit. Before the 383s were defactored there were not any single 4 barrel 383 Stockers out there with maybe a rare exception. The 383 is Mopar's most common engine, it's what the 350 is to Chevy. For many years a Mopar racer had to run a Hemi, a Max or 6 Pak car to be competitive with a big block, all expensive combos as well as the cars they came in, thankfully that has changed.

Certainly would agree they needed some help.
Similar 389 / 400 Pontiacs are in the 325 - 330 range.
Of course, those who were around in the 60's already know and understand that.

Not the '65 tri-power 389. It's still at 360 hp. Because they allowed the '62 318 hp tri-power down to 280 (H/SA) I've been requesting the '65 tri power to get within 10 hp of that. There's not enough difference in the two to shake a stick at. .007 more lift. Same carbs. 1.88 v/s 2.02 intake valve. That's it. Two years I've been trying. They won't budge on it. Don't feel real happy about building the car and giving them data for a year or two to prove it. But I gotta dream. The only '65 GTO tri power 4 speed in Stock.

Couldn't agree with you more Paul. 280 may look low but the carb and limited cam selection definitely still hampers the 383

Jim Hale has proved time after time that.............................................. ........
Old age and treachery will overcome youth and skill.....but it sure doesn't hurt to have 45 HP removed....LOL
