Given that I already have lots of gear and convertor, the Comp 20-702-9 R308 grind looks quite compatible with the rest of my package. 575 lift, I & E, 262 dur at .050, 110 deg lobe centers. I don't think my heads will support much more than that lift wise, and it seems as though I need a bump in duration as much as anything. Has anyone here ran that stick in a 340 or 360? I'm leaving at a good 4500 convertor flash, shifting at 6800, and hitting the lights at 7100, so I might as well get a cam that will work better from 4500-7000 than my current.

Without knowing what the heads flow or what they are I would think more lift.... if you go to the max flow on the lift, you only see that point once... BUT if you go above the max flow lift point you see that max flow 2 times... I know it helped mine... I'm planning on going larger yet

I just had Bullet grind me this one, Not sure if it'll wind up in the current Airwolf headed 414 or in the W2 headed Tunnel rammed 440. Similar grind to the one Mopar Dave runs in his 408" cuda, a little wider lobe spread since my car's a little lighter. 8006144-BulletCamcard.JPG (84 downloads) 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

Whichever motor the bullet winds up in the other one is getting this cam since it'll be a perfect street/strip roller. If this one stays in the 414 I think I'll go to 1.6's since I know the motor will like the extra lift. Don't mean to jack the thread buddy! As for the "over the nose" theory it still applies but but it's a lot less critical when dealing with a Roller, Definately applies to a flat tap since there's no effective Dwell over the nose, you need more on a FT to try to emulate the roller's ability to 'park' the valve for several degrees. Getting a roller "perfect" has as much to do with the Flanks (ramp area under the curve for the flow window)...maybe more, (especially with wedge heads) as it does with the "square" part of the lobe.

Pretty similar to the one I have for my 340 with 12:1, W2's, victor intake and a 4150 carb. Guess it will like some rev's.... Plynouth VIP '67 TT IC EFI

They're mildly ported and port matched. I like the Comp grind partly on the basis that the ramps are a bit less radical so it should be a little less stressful on the valvetrain. Keep in mind that I also run 1.6 rockers, so I'm probably close to maxing out on what the heads will provide at max lift anyways. It took a lot of ruminating while driving down the road to wrap my head around the notion that the reason my car slowed down when adding gear was that I was now spending more time past the torque peak as the car moved down the track. Going from a 240 deg @ .050 cam to a 262 @ .050 should theoretically put the car back in the fatter portion of the torque/horsepower curve going down track. I could get my head wrapped around it until I went back and looked at the time slips. After picking up .05 in the 60, the car was back even at the 330, and then lost ET and mph from that point on. Not enough cam duration makes sense.
