Help with my 5.0 combo !!

I hope I didn't come across bashing you or Mr. Grubs (don't know him).
There isn't a whole lot, but just a few:

The reason being is that the Motorsport cams are a dual patern roller cam.

None of the ford motorsport hydraulic roller cams are dual-pattern. D.Hearne had it, but they are all single pattern. All of the letter cams are based off old technology. Just as the fastest guy on the street 10 years ago was running mid 13's, cam technology has come a long way. The B-cam (one of the oldest) is only .480 lift because E7TE heads stock don't flow much past that. The F-cam is the lesser of all evils because of the valve events pertaining to the intake. They work on basically ported stock heads because it lets in enough intake charge to actually make some power.

What he told me is that the AFR heads flow exhaust so well that a dual patern came doesn't work as well with those heads as a single patern cam.

That would theortically make the letter cams exceptional for the AFR heads. And that is simply not the case as stated above. For a given combination, 99% of the time there is a better off the shelf cam. True, a single pattern does better with heads that flow significantly, but the fact is what is good enough?

Newer trends lean towards dual-pattern camshafts because they fill the small block ford head niche. Not everyone can afford AFR/Twisted Wedges that can support a single pattern effectively. Typically a small block ford head exhaust ports flow is disproportionate to its intakes. Cam grinders use more exhaust duration to get all of the exhaust gas out before it closes.

Hope this helps a little.

You can still make a TON of HP with letters cams. A custom can always do better because it is custom. But there must be value to them since everyone that sells an off the shelf cam compares their grind to a letter cam. Iv'e never been let down by one by any means. Even now.there even people now using that old technology to make 1200 rwhp. Not a bash on you fairlane, or anyone. But I think too many people count them out too quickly.

Thats what I had added in my first post.
I know of two cars:
85 gt gutted, ported GT-40 irons, cobra intake, full exhaust and an e-cam and it ran 7.60s @ 90 on the motor in the 1/8

90 gt full interior, ported GT-40 Y303s, cobra intake, full exhaust and an f-cam and it ran 7.50s @ 92 in the 1/8

So yes, you can make power with the letter cams (the z-cam is by far the worst however). And I did see that thread awhile back with the f-cam making 1200hp but you have to understand that is with a turbo setup. If you have a built enough shortblock it really won't matter what cam you put in it. This got brought up when I was talking with brad brand (street outlaw/10.5 outlaw) and he also shares the same opinion. Cams in turbo motors just dictate how efficient it is and how streetable it is. The power level is usually just dictated by how much boost your block and rotating assembly can go.

So to conclude, if you aren't concerned with going the fastest your setup can go, then go with the letter cam that corresponds to the RPM range the motor will see. I just wanted to point out that usually the letter cams can be beat across the entire RPM range if you spend your time picking a good OTS cam. Which is why I stated the wolverine 1087 cam . . .

Can add me to that list with a X-cam.
