Solid Roller Cam Choice
After speaking with most of the major cam manufacturers, I've come up with two grinds what I feel are close to what I need for this motor. I'd appreciate input from you folks who have experince with this type combo. Thanks.
@50 @50 Gross Lift Int. Exh. Dur-Int. Dur.-Exh. Centerline Isky: .650 .654 282 288 112 Crower: .707 .700 270 278 112 The application is a 500 CI 8:1 Static Comp. non intercooled blower motor, 8 pds boost. 350 cc runner Canfield Aluminum Heads. Stainless Marine Exhaust 4" wet and no mufflers. 4000-4500 Pd boat that needs to still pull skiers, haul ass at river and travel in ocean 35 miles out or so and back reliably. Thanks for input folks..... |
Cam grinds look good, but I don't think the wet exhaust will like the cams much, with them cam choices, you will need to run dry pipes, or you will probably have water reversion probs. just my .02

I like the Crower. We had a Bullet cam with I697, E 697, 262 and 272 duration. Pulled like hell on the big end.

Are you blown? I ran normally aspirated last year on the same motor 612 I & E lift. 240 & 245 Duration on a 112 centerline and is way too small for my now blown application...
