Not enough meat around intake manifolds ports so that I can open my Bulldog heads to MW ports. Any ideas from you are Great!! Last edited by 4406brl; 12/14/14 10:01 PM.

It had a set of Eddy RPM heads on it that where CNC ported with 440 port sizes, not M.W. port sizes. It did that through the full 3 inch exhaust to the rear bumpers and three inch tall K&N sixpak air cleaner on it, all on Oregon 91 octane pump swill Your deal will be traction limited just like mine was Good luck, have fun and let us know your results with the sixpak on it Last edited by Cab_Burge; 12/15/14 04:28 AM.

It wasn't really sensitive to the rpm, have no idea of where it made its power, but we pulled it to over 6000. The heads were homeported, the intake was a Team G with a dominator and run with pump gas. It was in a 3600 lbs car with a powerglide(?, wasn't my idea) and 3.23 gears with 275/60/5 ET Street radials. It run 10.4 in the 1/4 mile. Plynouth VIP '67 TT IC EFI

Ran a best of 10.67 @ 128 And had nice street manners drove it everywhere I do however like the idea of the Indy intake mentioned earlier. Then you can port those heads and really attain your goal...

The rpm for torque and hp will be very low even with a tunnelram using standard port heads. I would be concerned about that Modman intake, and research it some before committing to it.

I guess the question would be how much launch rpm it would take to make it work with the stick? 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

And that is my problem now. dumping the clutch at 5K and too much weight. 4.10's and 2.66 first gear and only 545 ft. tq. at 4300.

I can understand that as I am glad my 63 is an auto as I could not afford to run a stick car the way I launch stick cars. Back in the late 70's early 80's I bracket raced a 340 Dart that ran a best of 11.90's @ 113 and it was a stock 833 four speed. Well I would bring the rpm up as the tree came down and I would bring it up to about 6000 and then dump the clutch and slam the gas to the floor on launch. And I would power shift it also but it broke a good share of parts racing it for 4 seasons. It was an 8-3/4 and I broke a few driveshafts and ring gear teeth along with twisting the axle shaft splines and all. But hey if your gonna race run it hard and I did . Now my 63 is over a second and 10 mph faster and I still have a stock 8-3/4 in it with a Detroit locker but it has not broke anything major yet to this date as I have raced it a few times a season since 2007. Just shows how the auto is much easier on the drivetrain parts. Ron Last edited by 383man; 12/21/14 03:57 PM.
