The same thing can be done locally.

not really, thumper is a genious when it comes to porting E7s. I have yet to see anyone able to reproduce his results....same goes for Tmoss ported lower intakes. match the two of them together and you've got one mean sleaper.

You should get out more often! Not saying there are many but there are a few. If you want to see a guy who really knows them check out:

Locally maybe for you but I live in Whitecourt Alberta, have you ever heard of it? Nobdy around here does any performance stang work!!!!

Where is this guy from?

All that guy is really doing is adding bigger valves...which in most cases casue P/V clearance issues. thumper has the option of GT40 valves but you are sacrificing low end tq for high end HP with bigger valves. powerheads is another option, but again you run into the bigger valve clearance issues.

do a serch at www.corral.net there is lots of info on those heads

Thanx!! :thumb1:

Really? Apparently you still need to learn a few things.
