what are the numbers stamped on the back of a stock HO cam? i helped my brother put an F cam in his 88 Mustang (still SD) and it runs exactly the same as it did before, no surging, no driveability difference. we are wondering if maybe it had an aftermarket cam to start with.

IF it doesn't sound like this.... http://www.youtube.com/watch?v=CoRW50mLnxI
Then your brother got screwed. It should have a noticably loapier sound to it. Also, it is not a speed density friendly camshaft either.

This is what is stamped into the back of the HO cam I just gave to Vinny. I measured the Lobes and with a 1.6 rocker they measure out to 0.444 so its definitively a stock HO. Perhaps your Idle is set too high and you cant hear the loap? This is the back end of the cam (opposite the timing gear).

it has F303 stamped in the end of it.

the came that came out looks nothing like the one in the pic. the only numbers on it are "08" and there are two dots and a notch.

1. Anyone can stamp letters into the end of a cam, I hope he bought it new.

2. If it doesn't idle like that vid the cam isn't what he/it/you say it is.

Sounds like he got stuck.
I got a B303 cam in my mustang and I can tell a big difference. But then again I have a few more mods done to it.

Did he buy the cam new?

Thats one thing I wouldnt buy used unless I knew for sure what it was. Cant really tell what it is by looking at it.

the car is starting to lope a little, but it's like the computer is not letting it...or the iac is keeping it idled up.

What rpm is it running at? What is your base idle speed set at? if its idling around 1100 it won't lope. What does the butt-dyno say?

he says it picked up some on top and lost a little off the bottom, based on the butt dyno.

i think its idleing at 1000-1100, we cant get it to go much lower

Get the engine warmed up. Disconnect your Idle Air control solenoid. Then adjust the screw for the throttle stop. Do your rpms come down? I am not sure what a SD computer will do with a F303 cam in it. I think they run rich. Sooty exhaust?

Seems like alot of effort to stamp F303 on a stock cam. Also, did you pick it up from his house?

If it's SD you aren't going to be able to idle a "F" cam below 1100 and keep it running... It'll just load up and eventually die...
