Edelbrock heads with roller rockers and an Air Gap intake with Street Demon 750 cfm. It has TTI 1-3/4" step headers to 3" collector. TCI 3K converter and a TCI 727. 8-3/4 rear with 391's in a 2 case. What's the best cam for this combo? No Stock

The old Ultradyne 231/239 @.050 Hydraulic on 108 in at 102 was always a great 340 cam WIZE World's Quickest Diahatsu Rocky (??) 414" Stroker Small block Mopar Powered. 10.84 @ 123...and gettin' quicker! https://www.youtube.com/watch?v=-mWzLma3YGI In Car: https://www.youtube.com/watch?v=PjXcf95e6v0

And if he's over about 9.5 I'd put it in at 105 WIZE World's Quickest Diahatsu Rocky (??) 414" Stroker Small block Mopar Powered. 10.84 @ 123...and gettin' quicker! https://www.youtube.com/watch?v=-mWzLma3YGI In Car: https://www.youtube.com/watch?v=PjXcf95e6v0

Cam made awesome low end and midrange power. Sounded wicked and very street friendly. Ran a best of 13.26 with 727 and stock converter. 10" converter put it into the 12.90s. Very happy with it.

Funny you say that. I have a Isky mega .480/232@.050 I removed from a "core" 360 I bought. I kept it on the shelf because everyone tells me how hard they run.
