.....I ran your combo in my Desk Top Dyno; 350, Dart 180 Iron Eagles 2.02 & 1.6's 72cc, 1.5 rockers, to get your compression ratio I used; flat top pistons, 0 valve releaf volume, .040 head gaskets, .075 quench, 72cc heads & came up w/ around a 8:5 to 1 compression. 600 carb w/ a high torque dual plane manafold, small headers w/ mufflers. And 5 different cams all of them the Comp Cams Xtreme Energy, Hyd Flat Tappet.

1. XE-250H, #12-230-2, duration 206/212 @ 1/2", .432/.444 lift. It put out 413 Tq @ 3500 & 346 Hp @ 5200.....

2. XE-256H, #12-234-2, duration 212/218 @ 1/2", .447/.454 lift. This put out 411 @ 3500 & 363 Hp @ 5500.....

3. XE-262H, #12-238-2, duration 218/224 @ 1/2", .462/.469 lift. Put out 412 Tq @ 4000 & 373 Hp @ 5500....

4. & 5. Cam #4 that I ran was the largest that was recommended for a stock converter but a 2000 stall was suggested {not sure WHAT the difference is between 'recommended' & 'suggested'???}.... Anyway this cam did 406 Tq @ 4000 & 384 Hp @5500. BUT the TQ was only 355 @ 2000 where as the first 3 cams were; 389, 379 & 371 @ 2000.... I would not use #4 because of this. Cam # 5 was just plain old 'way to big'.....

I also would not use #1 as it fell on it's face between 4500 & 5000. I'd go with # 2 but #3 would work.

THIS IS JUST MY OPINION THOUGH!!!

It's not that I'm all that knowledgeable, I just have a Desk Top Dyno!!!! Call Comp Cams and ask them & let me know what they advise. I called them a couple of weeks ago for a recommendation & went one size smaller...... hope this helps ya, Bill
