Big Block Drag Race Cams , what are you using
I have a 64 Dodge 330 drag car 3350 lbs with A 541 B1BS HEADS PORTED Iddy 449-2 int. single carb 4150. Per rules. T.F. 8 in 5600. 4.56. 10.5 29.5 w tires. The car doesn't run like I think it should. The cam is a roller ground for a 446. I had same combo its 273/278 .645/.630 on 107 ls. I think I need more lift 690-705 & more dur. 280-288 & 108-110 ls.

I'll just throw it out there for you.... I think the cam could / should be around .800 lift 280-290*@.050 with 7.1 Rocker ratio. with the heads flowing about 370 or better. should be a tad over 800HP with them heads...
I would look into the Indy R2 or CM2 camshafts with the 1,7 Ratio. (Also I dont think the Intake is big enough along with the carb 4150 and maybe a 900CFM with a spacer, If thats what you are running?) I would want to see flow a little more air with a 440-3 intake and a 4500 1200CFM-1250CFM and see if that picks it up...
I havent had a B1MC headed Motor in a long time, Things have come a long was scence I played with them....
However, Not sure what direction you are looking to go. But you may try speaking with the Nickens Brothers over in Conroe? That being if you get no help in your area...

I don't have that much motor. The heads are B1BS the sportsman heads. They flowed 335 @.600 before we opened them up to Max Wedge. I am limted to a 4150 casb. NSS rules. Going to buy one of the twin blade carbs a 1200. I have Comp cam. That's 287 .690 both intake & exhaust on a 108. Thats about all the lift I can get. Coil bind at .740. Right now you can't hardly get a cam. They are short on cores & 2 behind
