I ran a ported stock lower that Tmoss did, and now the new motor has a Tmoss ported gt40. VERY nice work. I was lucky to be able to watch him port my gt40. He showed me alot of the problems in the casting as well as explained the idea/theory to what he was doing. Not to mention he was preaty darn quick at it and made it look realy easy.
The Tmoss stock intake was a realy good mod, the port sizes were the exact same size as the intake ports on the stock unported gt40 iron heads. He could not have done a better job, and this was without seeing or knowing what to match them to, just his port work that he does to all the stock lowers.
Now with the build in the final steps along with a few unexpected pop ups I hope I can get some good numbers soon for Tmoss and Thumper.
