440 built by Gary Hettler Engines who builds engines for Stock& Super Stock classes.
1966 440 .030 Forged 11:1 pistons, steel crank, MP .590 lift solid cam, 906 heads ported, Crane Gold roller rockers, Edelbrock TM-7 intake, 6 qt oil pan. Balanced and blueprinted. I put an 850 DP on and the distributor is a stock electronic with light springs 36deg timing, MSD 6AL box with a Blaster Coil.

All steel, except fiberglass hood 1972 Demon, full interior with 12pt mild steel cage. 20gal Harwood fuel cell running 1/2" fuel line to a Holley Blue pump.

727 Torqueflite, cheeta manual valve body, 4:10 spool, 325x50x15 BFG's (27.8" tall), Cal Tracs on soft stock springs, Adjustable Koni's set on 90/10.

What should it run in the 1/4 mile, and what kind of HP/Torque should this make?
 
I would say you would run 10.80s at 122 mph. Your hp should be around 535 or a little better.
 
So I should jet the carb up to mid 80's, it's mid 70's now, and try launching from a higher rpm.
Will a lean condition cause lower mph?
When I had it at the track last time, it 60' 1.65, and the mph was 113.
 
17.56 @ 47 MPH. It'll have 105HP and 122 LB FT of torque. Gary who???


:toothy10::toothy7:
 
mid to high tens would be my guess, the heads though is what would really make or break that combo so its hard to know for sure what it "should" be running

set the 850 dp to stock jetting....jumping 10 jets size is not a good idea..
