What kind of cfm were the heads making after being ported.
 
I used to have a 360/380 hp crate motor in my D50 and it ran a best of 7.27 @ 95 in the 1/8 at 2950 lbs. The motor is a stock 360 Magnum. I think it is 9-1 comp. stock Magnum heads .501/.513 Hydraulic roller cam. It had BAD exhaust on it. They do not sell headers for a D50 so it had 1.5 in. block huggers with 2.5 in. collecters with 3 in. Flowmasters. I think it would have went alot faster if it had normal headers on it. I think that is in the 11.40 range in the 1/4. I built a 394 ci. pump gas small block and put in it and went over a second faster and 15 mph.
 
11.70

440/727 in a 69 dart Gt. 4.56 gears. 28" DOT tire. MPP 284/528 cam. 950 carb. TTI's. Eddy heads.
 
10.05 at 135mph

408/904 in a 1966 dart 4.56 gears 29x10 Hoosier slick, Cam 268/272 with 0.725" lift. Indy 360-1 heads cnc ported. Quick fuel 750cfm carb. Fender well headers.
 
Hope you don't mind me chiming in but anyone running a 383 stroker ?
 
Close, I have a 400 stroked to 500, Eddie heads, Comp hydraulic roller, Street Dominator with a 750 DP, 1 3/4 headers into full 2 1/2 inch exhaust, 3000-3500 convertor, 355 gears, 28 inch tall drag radials. Best so far in full street trim was 11.53 at 118 mph. I've never weighed it but my guess is over 3700 lbs with me in it.

Sharp ride. I bet if you uncapped it and ran a 950HP it would pick up a bunch.

How much horsepower don't forget that guys
 
If I uncapped it and added a bigger carb, no doubt it would go faster, but I would likely get my a$$ kicked off the track, since the car has no roll cage, and I don't want to install one. So its just some fine tuning now, since it's mainly a street car.

As far as horsepower, it dyno'd at 550 HP and 610 torque with my home ported 452 heads. It has not been back on a dyno since the Eddie head swap, but I picked up about 2 1/2 tenths in the quarter, so probably another 25 HP and some more torque.
 
I run a 950hp all the time on my 440. works great on and off the track.
 
I bought a new Holley HP main body for my 750, the one with no choke horn and adjustable air bleeds etc. We'll see if that is worth some horsepower or not.
 
400 stroked to 499,3550# with me in it. Eddy heads, victor intake, 10.9 comp, Comp cam solid flat tappet, 950 hp. 727 mvb, strange S60 with 373 gears, 295 drag radial.
10.79 at 123 mph through full exhaust.

My wife's dead stock '66 , /6 automatic w/manual brake and steering weighs 2810.

Add up the extra weight for the drivetrain you have and then subtract for the replacement or missing parts. AKA, aluminum, fiberglass, missing jack, etc.

That should be about as close as a good guesstimate gets until you hit the (accurate) scales.
