I just bought a set of AFR 185's and was wondering about my pistons. They are Keith Black Flat top, with two valve reliefs pistons. Will i have trouble with the piston and head clearance.
depends on the cam&rocker ratio, but probably not, but Id still check it. its more work but time is free, new valves are not.
this a race car or street car?
I'd have to disagree, not saying Z cam is the best out there, but it has a excellent powerband and will definatly net 400hp on a carbed 331 w/ AFR's. No doubt about it. Im sure FRPP put a good amount of research into the design.Most aftermarket pistons have enough valve relief for most street setups. Wouldn't hurt to check it though. If you're looking for 400hp, I would stear clear of a letter cam. The letter cams make the car sound nice, but do little for performance. Hence the term "noise cam."

I hear bad things about letter cams, but after seeing that thread with a 400hp motor with a stock cam, a letter cam seems a step up from that, and seeing i will have better heads, and will do porting work to the heads and intake, and not a stock cam i would like to have better HP. Eventually i will get a custom cam but right now, i am going to be cheap.
I see complaints about the letter cams, but what about the trick flow and steeda cams, what is the difference between the 3, that makes 1 so bad, and others love the steeda and trick.
Letter cams were designed in the early 80s. If you were upgrading your computer would you take out the pentium 4 and put some vacuum tubes in? They use identical intake / exhaust specs for both lift and duration.

400hp with a stock cam is the exception. I personally have never seen an engine with a stock cam make 400hp N/A. Maybe a trophy stock car, but those aren't really stock cams. If you are expecting 400hp out of your engine, you are looking into something in the range of a Trick Flow 2, and some pretty stout heads.

AFR 185 is a very good head, and will definately do the trick. All of the Trick Flow cams have more lift and duration on the exhaust. Look at the duration from .050" to .050" as that is what is really important. Advertised duration doesn't really matter much.

Z cam didnt come out till like 01 or 02, maybe 03. I know cause when I bought the X cam it was the biggest one avalible through FRPP.Letter cams were designed in the early 80s.
ok thanks
What is the difference in power between that cam and the z303. Is there any charts i can search for you that you know of.
I am trying to learn as much as i can about cams
