Anyone run these cams? I know they are regrinds. I have an opportunity to throw a set of these on while my heads are at the machine shop. The car is a 99 Cobra built 5.0 stroker with a .70 turbo. Also, if anyone is running them, any sound clips, gains, etc?


Thanks!!:beer:

one more comment about the SHM cams- and this bugs the shit out of me- how the **** can you regrind a cam to make it bigger than it already was? makes no sense. yeah-if everyone could send in stock cams and SHM turn them into big cams-everyone would do it.

Regrinding cams to increase duration and lift is actualy normal to do. The way they are doing it is by reducing the base circle of the camshaft(I belive thwy do it .050") which is why you have to run spacers under the lash adjuster. As far as the orignal posters question though, I had problems with a set SHM regrind cams. The modular ford camshafts are very sensitive to run out on the base circle. What basicly happens is the lash adjuster will adjust to the lowest spot on the base circle and hold the valve slighly open on the rest of the base circle. The engine will make basicly no cranking compression and be down on power and hard to start. It may have been an isolated experice I had but I doubt it.

HP regrinds > SHM anything however why not just get billets? Do it once and do it right.

Precision and accuracy can't be replicated with a regrind as well as they can when starting off with a billet blank.

I called HP and he said they are billet (the one for sale here) I asked him a lot of ?'s. My car is a 99 Cobra built 5.0 Teksid with 8.5.1 compression. Single .70 turbo with a .68 a/r exhaust housing. I will be upgrading later to a .76 / .96.. HP said these cams will be fine, and I could send them i to redo the exhaust if I wanted to....
