I hear you and hopefully one of them will chime in so we can hear it from the horses mouth. I did speak to tick before building this setup, i just want to see what my track numbers are or on another dyno. Thanks for your input though.

That's what I thought but I saw a guy lose 30rwhp after installing a S60. Ive never seen that high of a loss with any rear.

Well, I made 401rwhp on a Mustang and then 390 with a new tune on a Dynojet (no misprint). As odd as it sounds, the car picked up 2mph in a far worse DA with the new tune, so obviously the Dynojet is stingy and the myth that Mustangs "always" read lower isn't necessarily true.
Your rwhp and mph is about identical to mine. I make 390 and trap 116mph in a full weight car with a 6 speed and a 9". But, I have stock 241 heads, TB, intake etc. Only engine mods are MS3 cam and headers. With that said, I think you're leaving a bunch of power on the table having better heads like those AFRs.

Tony Mamo would agree with you too. He like cams with less of a split and a LSA in the 114 or so range.

Just to let everyone know, I spoke with Tick performance and told them my plans before purchasing a cam and they recommended the Polluter V2 cam. They also knew I was going with the AFR 205 heads. They are a leader in the aftermarket automotive industry and I wouldn't think they would lead me in the wrong direction, but everyone has their own opinion, and you are free to share that opinion. I want to either get the car to the track or on another dyno and see what the outcome will be. Time will tell. Thanks for everyone's input.

I don't think that cam is wrong for those heads at all, but from what Tony has said in other threads, and through many PM's he and I have had, he would not think that cam would be optimal for the AFR heads. With that said, each cam guru thinks a little, or a lot, differently when specking cams. You get guys like Tony Mamo, Martin Smallwood, Ed Curtis, Pat G, Kip Fabre, etc. you are going to get 5 different cam suggestions.

Mph seems way low for the power. You should be at 120-122 with that power and weight.

My problem with this is you are judging this based on duration and LSA.

I do not spec cams based on duration and LSA.

I spec them based on valve events.

I can have 2 cams, both with the same LSA and duration, but both have different ICL and ECL which will alter the valve events.

You could look at both cams and say they will perform exactly the same, yet they will not.

For example.

239/244 111+2
10.5
48.5
55.5
9.5

239/244 111+6
14.5
44.5
59.5
5.5

These cams will perform differently, but if I just told you they were both 239/244 111lsa you'd assume they wouldn't.

Tony has always said he likes 0-4 degrees of split. This cam has 5. Not much different?

Pat G's camshaft that made 500rwhp + in his own personal 4th gen was 236/240 111lsa. He had AFR 205 heads.

The restriction here is the cats and stock muffler he dyno'd it through.

If he had opened the cut-out there would of been an easy 15-20rwhp gain. Possibly more.

If a Mustang Dyno is truly operated correctly and the operator inputs the correct parameters to apply the correct amount of load on the dyno brake then the numbers will be 10-15% lower than a Dyno Jet.

I don't think his numbers are bad at all. Every dyno reads differently.

If you have the time here is my personal experience on the AFR 205 heads, Cam choice, and Tony's expert advice. Long story short I had 222/234 115+3 cam Stock AFR 205 heads made 451/403. Changed to a 235/235 113+3 cam and did some work on the heads and made 484/412 on a stock bottom end ls6. Then later on i switch to a stock bottom end Ls2 kept everything else the same and made 493/435. Full mods In sig.

If it helps you compare, back in the day, my car dynoed 396whp on a mustang dyno, and it trapped 114.7mph. 1.8X sixty, 6 speed, 10 bolt.

What was done to the heads?

You also went to a bigger cam, I would highly doubt anyone would argue that adding 12 degrees of intake duration wouldn't gain power.

Bludevil415

The heads were ported and milled.You are correct i went with a bigger cam.But i also went from a cam that was not designed to work with the Afr 205's to a cam that was.What are the specs on the polluter cam? Tony Mamo has stated his self that the Afr 205's likes single pattern cams. I am no expert by any means im just sharing my experience thats all. A cool fact, on the main page Tick website there use to be a my name and a picture of my EB C5 Z06

My 99 TA with TEA stg 2 heads 63cc, SNS stage 3 cam, ls6 intake, bolt-ons, ss3600 stall, flt 4l60e, and S60 w/ 3.73 detroit locker made 424rwhp.

Hit the track, exhaust setup sure is damn eating some good HP.

Make any more passes? Heck I went 12.15 trapping 114 with just a clutch, full exhaust and mt's. Heads and cam if I only gained 2 mph id be confused

I disagree that AFR 205's NEED a single pattern cam to make power. Completely.

Rise of the Phoenix

iTrader: (27)

Pretty sure you proved that theory to be wrong.

Bludevil415

Im sure they can make power from any cam above stock. Tony Mamo says they make the MOST power on single pattern cams. If you look at most of the cars making 470 and up on the afr 205 heads most of them have something in common and that is a single pattern cam.

Rise of the Phoenix

iTrader: (27)

Pretty sure Dr. Whigham did this with not a single pattern cam. Most of the AFR head/cam combos that I've seen make the most power are not single pattern cams.

The uber famous Pat G AFR 205 combo that first made over 500rwhp with a stock bottom end LS1 engine had a 236/240 cam on a 111lsa.

LG used to use the AFR 205's a ton back in the day with there 234/242 112 and 114lsa G5X3 cam to make 480-500rwhp.

I look at valve events before I look at duration numbers. You can be led astray by just chasing duration figures and not calculating events.
