Single pattern cam yay or nay

Okay, on a ford truck forum someone told me that a single pattern cam wasn't going to make my 460 happy.

What do you think? Its pretty radical if you ask me and my engine will probably love it.

Single pattern camshafts installed about 6 degrees advanced from split overlap work well for low and mid-range torque applications. Not so well for higher RPM horsepower with production type heads.

My builder said that 5 degrees advanced was a lot for a street engine. Mines max street with still being able to run high 11's low 12's. 550hp@5000 rpm's. In the dyno simulation 2 degrees is better than straight up. I'm not so worried about the top end.

I can simply see you already have your mind made-up and are just looking to get some kind of verification here so, whatever you have heard from your engine builder and simulated dyno programs are probably better information than I could ever hope to provide from actual experiences.
Go have at it ...

Well I want to know if this is true and if this is a good cam. Plus I will be building lots of bbf's down the road and this info will be very use full to me.

-Thank you for helping me, I appreciate it.

I have ran this cam at 10:1 compression with stock C8 heads with just the bump ground out of the exhaust port. It ran great.
Stealth intake with 1 7/8 headers and a 3 inch exhaust. Probably a no-no but I had a 2 inch adapter and a 1050 dominator on it.

I had mine in on a 104, 5 degrees advanced.

Put it in like Randy said............. It will run great.

The headwork you had done is what was done on mine, plus the builder ground down the valve guides and put 2.12/1.76 valves in it. They are 1971 D0VE-C heads. Thanks for the input, its nice to know people have ran the same cam with a similar build.

imo if you get a custom ground cam (only like $20 more when i bought mine) you will get a cam that works well for YOUR motor. unlike choosing an off the shelf grind which is just picking the one that is least wrong for your particular build.

check out a few of these guys websites.
if nothing else it will help you to understand who some of the guys are on here that offer free advice.

I always thought you wanted a dual pattern cam with more on the exaughst side..at least with factory heads like D3s.

For the most horsepower ... yes - however, torque BELOW the torque "peak" will suffer from opening the exhaust valve sooner with the lower compression ratio.

I had a dual pattern cam in it first A 225-235 on a 110 c/l and the single pattern cam would run circles around it.

I just figured no more cam than was in it and no more power than it was making that it had enough exhaust to get the job done.

Maybe the dual pattern cam was over scavenging the intake ? How much exhaust do you need to make 500 hp ?

My 557 with a 404 cfm intake port made enough power to run 5.80's at 3160 lb. with an exhaust port that only flowed 196 cfm and had only 8 degrees of split on the exhaust. That's only 48% exhaust to intake ratio.

Hell that can't work, the Chevy guys have always told us you need at least 70 % to make power like their heads have.

Randy ..... all you can do is try!
