Should I keep these heads?

My un-blown combination wasn't very far from the one he's using.

My car is (look to the left) a '72 4-door; probably 250 pounds heavier than the Barracuda he's building; there's .25-sec right there....

My engine's specs...

360 Magnum stock short block
Stock Magnum heads with a bowl port only 9:1 true compression; stock, dished pistons
Early 340 cast iron exhaust manifolds with a complete TTI 2.5" system (H-pipe), Dyno-Max Super Turbos
Low-performance (water heated!) aluminum 180-degree M-P intake with an out of the box, 3310 Holley (750 vacuum secondary). Stock jetting all the way.
Windage tray
Stock-type, curved M-P distributor and an Orange Box.
Hughesperformance cam.... VERY mild! Only 214/218 @ .050, but with lots of lift (.525") Ground with 114-degree lobe separation. Idles at 475 in gear, with 14 inches of vacuum.
Good to 6,500 rpm, but stops pulling hard at about 5,600.

904 with a Trans-Go shift kit and a stock 318 converter; 2,500 rpm stall (lots of low-end torque with that cam!) Stock 2.45 first gear ratio.

The cam is a reground Magnum hydraulic roller using 300# springs, heavy duty pushrods and Crane roller aluminum rockers. All from Hughes...

8.75" 'unlocked' rear (no sure grip) 3.91:1 ratio with 8"-wide BF Goodrich T/A Drag Radials (J-U-N-K.... stay away), with stock springs and an air bag on the right rear.

The bottom line:

On a 95 degree day at sea level (Sacramento, CA) it ran a best of 13.35 @ 102 mph, with a best 60-foot of 1.91. I had to leave at 1,200 rpm... no bite. Driver wt. 250... :angry7:

My Magnum heads might be marginally better than 360 L-A heads (just a guess; I don't know that for a fact), and my roller cam is probably more aggressive on the lift than a flat tappet, but his 250 pound early 'Cuda weight advantage over my '72 4-door sedan probably cancels all of that out.

My advice is to call Hughes and tell him what you want (ask for Dave), in the cam department. They only do Mopar stuff, and they're very good at what they do.

Good luck; I think 13's will be easy for you.
