I believe 66 Wagon with 383 4 Brl.

pretty sure I am correct.

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...

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.

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

That's a closed chamber head, small exhaust valve and about a 525 cfm AFB. I would guess a low lift cam, like to know what rpm he's turning too. Doesn't matter how much hp was taken off, other than what class he's running, 11.65 in a 4000 lb shoe box is doing real good.

looks like 426/365 down to 291 .smart man/soft combo. Why would anyone want to race anything but a Mopar.Same old Sh&t dinner from NHRA and we keep on eating. Rick I am wrong.thought it was a 65 wagon /383 325 down to 280 0r 285 with alum. head. Same meal just a different entrée.I stand corrected. Rick.
