Thanks, it's a 3300# Duster with me in it. 275/60/15 drag radial, bone stock suspension, one new leaf added to each spring as they were sagging. 727 trans, 9.5" dynamic street converter, 8.75 rearend with Yukon nodular center section and stock 3.23 gears, Moser axles and spool. Small 1.75 headers, mechanical water pump and fan, never runs hot. Indy intake with pro-systems 950 carb.

Without any specific horsepower or ET goal, I’d say you could achieve good results with either std or MW port. If I were starting from scratch, I’d probably lean towards the 270’s and run the Indy 2D opened up to match the heads.

My combo is wilder than your looking to build, but in my opinion it works good on the street. 67 Barracuda, 3300#, 512@11.25:1,270@50 solid flat, 5200 8", 4.30/28" tire. Vacuum idling in park is 9" and 7" in drive. I'm using the MW Edelbrock victors with CNC by Hughes Engines. Heads flow 356 from .600 on up and port measures 330cc. It will soon be getting a 3.73 gear as i think it can handle it just fine. Haven't been to the track yet,but i am expecting easy mid 10's and should go low 10's on drag radials. Currently using Hoosier QTP and i can break those loose at 45MPH in 3rd gear. Plenty of grunt for the street and resently drove 60 miles to a car show in 92* humid weather with no issues other than it was very hot inside the car. I would go the the 270 head with not much to loose down low. 512's make alot of torque anyway with that 4.25 arm. One other thing, my 8" 5200 vert drives like a common 3500 stall or better. Got it from Dynamic and refreshed by Lenny. Very nice piece. Hope this helps.

I had three different sets of heads on my old pump gas Duster stroker motor, a set of 906 ported big valve heads, a set of CNC ported Eddy RPM heads. I used the same intake and carbs on both of those, I saw .2 ET (10.69 to 10.49) and 3.2 MPH(124.5 to 127.8 MPH) increase in performance on that swap. I dyno tested two different sets of Indy M.W. intake port heads, a set of SR and a set of CNC ported 440-1, I used the same intake and carb. on both sets of those heads. The 440-1 heads made 50 HP more on the dyno but I didn't run them on that motor at the track. The car ran a best of 9.993 at 134.6 MPH on Oregon 91 octane pump swill through the 3.0 exhaust system exiting at the rear bumper with the SR heads and a 400-3 intake and a Holley 1050 CFM # 9375 non HP carb The right foot controls how far open the throttle blades are open, doesn't it The camshaft, intake and carb and cylinder heads determine how many CFM the motor will consume at WOT Keep in mind though that I am a drag racer first, not a street racer or show car type of guy

I'd like a cam head combo that would have a long flat torque curve and could take advantage of flow at .600" occasionally and not Reve past 6500. The car is a 65 Coronet, auto, manual brakes, 3.91 gears. This description doesn’t sound like someone targeting the 10’s. A pump gas 505 with std port heads and a low maintenance solid flat tappet will easily make 600hp & 650ft/lbs. My suggestion for the 270’s is really based on the possibility the OP might want to up the ante down the road, and that’ll make it easier to do should things go that way. But as for what the original goals are.... easily achieved with std or MW heads.

1968 Dodge Charger,4050lb with me Street car, COLD AC, 512 low deck, 440 source stroker kit 9.7 compression,Morel high rpm roller lifters, Hughes hydro roller cam 255,258@.050, .608/.613 lift with 1.6 T&D rockers with B3 geometry correction,Trend push rods, Indy 400-2 intake that I ported to max wedge,1050AN 4150 pieced together carb, 440 source Super stealth heads max wedge size that I ported flow 330 @ .700, with Farrea valves, Comp Beehive springs, 1 7/8 headers, full 3" magnaflow exhaust & tail pipes. A518 overdrive trans,4000stall lock up converter, alum driveshaft, 3.54 Strange Dana 60, Caltrac bars & split mono springs with sliders. 325-50-15 MT drag radials street. drove 80 mph, 80 mile round trip to the track, dropped the air pressure in the rear tires, turned of the AC & made a easy , short shifted pass,11.33 @ 121, next pass went up against the converter 2500 & it blew the tires off, got to hot outside for me, drove home in the ac. smile
If I had it to do over I would get the Trick flow 270, even though I did my own port work I have a lot invested in these 440 source heads.

An "on demand" power adder like a small shot of nitrous allows you to have a reasonably mild street engine/converter/gear combo.
Open the bottle, spray a small plate shot and dip deep into the 10's and possibly 9's.
Nitrous loves a 3.54 gear and a tight converter.
My build thread details how I installed my system and the results.

I got the high rpm Morels, kinda pricey, I went hydro roller after having a solid FT failure,I have 1000 miles on it since the change, my valve train is not the quietest in the world, my cam has a fairly aggressive ramp,this car is a BLAST to drive, I just got home from a 75 mile freeway run, if I had the gas money I would do that more than a couple of times a week LOL. so far no tuning,1st easy pass 11.33 @ 121 1750 DA

What cam cam and lifters we're you running when you had a failure? Did you lose a lobe? That is a nice pass especially for a first run! I had a Howards cam & Trend Tool steel lifters, running the hard lifters made it fracture, Flaking the nose of every lobe, That is what Dwayne suggested as the cause & I agree with him, quite a few people have had the same results that I did, I probably would have been ok if I had not used Tool steel lifters, very expensive mistake,although cam & lifter people said things would work GREAT LOL, I just did not want to take another chance on Solid FT cam again, a lot of people have NO problem with plain EDM lifters.
