Money vs Horsepower

Both of you have reinforced my idea on my engine. I figured they would require the same machine work on the heads, except it seems like rollers like more installed height and I'm not sure how much I can have cut on my spring pockets (they are eddys, and I'll be running cups/locators also.)

I have heard the same thing from Hughes, I forgot about it until you mentioned it. I don't see why they wouldn't make nearly the same amount of power! I think I may have my mind made up. I guess I'll throw out the specs, so maybe I'll get a yay or nay.

1970 340 stroked to 422, JE pistons/Eagle H-beams/Scat forged crank. Main girdle. Block decked for zero, lifter bores bushed, priority main oiling mods, balanced, etc. The usual. It wasn't built by me, but I have seen/heard it run. Edelbrock closed chamber heads, ported by me, giving me about 11.5-11.7:1. Crane Gold Race rockers, Victor 340 intake, Holley 850 DP, TTI 1 5/8 step headers. 1973 Dart Sport 340, 904 with man valvebody and 3500 stall, and either 3.55 or 3.73 gears.

Roller cam: 278/285 adv, .604/.600 lift, 245/252 at .050, 108 ls
Mech Flat: 288/296 adv, .586/.606 lift, 259/267 at .050, 110 ls

I know there is a big difference in duration, but thats what was spec'd out to me by Bullet and Lunati. Both cams seem to have what I want in RPM range, etc tho.
