Just trying to figure out which cam to go with since I changed my plans from a Super Ram to a Carb. I'm looking to run low 12's consistently. I need to stay 11.99 or slower to run in the street class at my track. It's a 350, AFR 195's, 10:1, 700R, 3.73 rear, full weight. Just looking to see what you guys are running. Thx.

Give these guys a call http://www.bulletcams.com you'll get 100 different answers from all of us with different opinions, when you really should be talking to the guys that do this for a living.

A lot of the guys on the racing boards i go to swear by these Bullet cams just like most guys swear by AFR heads. They dont get the publicity like Comp, Crane, Lunati, etc...but publicity is'nt everything. These cams simply make more power with less stress to the valvetrain- period. After I got my car running right this cam sold me and will be the only brand I'll run in the future. More with less. My motor is 2 steps lower in compression, .60/.80 LOWER lift, and my set-up is 600lbs heavier than the truck I run and brother in laws Regal with the same displacement motors and bigger heads, and guess what?? I'm running almost identical times ON PUMP GAS!!!

Have ALL of your cars information ready because you will be drilled by the tech at the cam company and be 100% honest of the cars true intentions weather it's gonna be a strip car, daily driver, street toy, etc.... It took about a week and a half once they decided what grind would be best for my application before it showed up on my door step. Pricing is the same as the other manufacturers, not to mention these guys were a pleasure to deal with.

I'm not sure the exact logistics of it, but I thought Ultradyne went out of business becasue of owner/tax problems. Now weather these guys just bought the name I have no idea. I do know many of the top guys that worked at Lunati and Comp were key in starting this Bullet cam business.

Dont quote me on that, just tyring to peice together all the little bits I've heard on the other boards from guys talking on the political aspect of it

Yes, Ultradyne is out of business.

Harold Brookshire, a well-known cam designer around Memphis who has worked for all of those companies mentioned above except Bullet at one time or another, is currently at Lunati. From what I hear, Holley is moving him, along with some or all of the rest of Joe Lunati's old company, from Memphis to Bowling Green though. I've known him since he was at Comp in the mid-late 70s. Ultradyne came along after that.

Some of the other people besides him from Ultradyne, along with some of the other long-time cam people from around Memphis, started Bullet. Bullet owns the old Ultradyne name and IP now, even though Harold is out of their picture. There's a bunch of good knowledgeable people there. They'd be able to steer you right.

AFR heads have much higher exhaust port flow than alot of other heads, for any given intake port size. Their heads DO NOT benefit from a split-pattern cam. They tend to prefer the intake and exhaust lobes to be about the same duration.

I'd think you'd want to look at a solid roller in the 240-245° neighborhood, and in the high 500s of lift. Replace the valve springs with whatever your cam grinder recommends to go with their cam, whoever you end up with; don't try to cheap out.

Yes, they usually do benefit from a split-pattern cam, ESPECIALLY so on a somewhat restrictive single exhaust car like a 3rd gen. When I purchased my 195s, AFRs tech line recommended the Comp XE 284 hyd. flat tappet for my combo. According to them split patterns almost always increase mid-rpm torque. In addition, they use split-patterns on all their SBC dyno testing.

I'd recommend talking to AFR about the cam recommendation. They know their head characteristics better than any cam company will.

Marc, have you run your car? You setup is pretty similar to what I'm going to be putting together.

As it is in the sig... it went 13.2@106

As it is now... same as above but without the Comp XE274 cam (Jasper Class 1 piece installed), probably high 13s just over 100.

I have a set of 1040 AFR 195s matched as best I could get to a Performer RPM with JET modified QJet, with a Comp XE284 cam, and a slightly used PI 3200 stall sitting in my basement. After spending all that, I'm out of funds for now. Fasteners, gaskets, a new water pump, rocker arms, pushrods, etc etc haven't been acquired yet. It's amazing how the "nickel and dime" stuff ends up costing several hundred dollars. But that's what tax refunds are for

Expecting high 11s, around 115 or above.
