It allows me to completely reshape the ports and entrance to the ports...essentially re-designing and improving on whats already there. Everyone assumes removing material is always the answer to more flow while if you look at the Eliminator SBC product line, I spent more time adding material to the right places (changing and ultimately improving the shape for more airflow). The major side benefit of a smaller port that flows more is a higher velocity charge for better cylinder fill (and more efficiency) and alot of you guys miss that or casually dismiss it when it comes to cylinder head discussions (and I have somewhat given up preaching it in some respects because Im convinced some people just dont want to get it....LOL). Once I have a proven prototype with the added material we cast a port around that new shape allowing us to CNC port a final part for all of you guys to benefit from. A ported stock head can never be made as good as a truly efficient, well thought out clean sheet design UNLESS you were to add material to the stock port (in all the righ places) via epoxy or welding which is time and cost prohibitive , not to mention not as reliable. Not much different on this manifold....I used epoxy to change and improve the shapes and contours of the runners and their critical entrances (where alot of flow can be found) taking a decent part out of the box and making it better and much more efficient. If I was in the manifold business we could take a splash or have all my changes digitized/X-rayed and than make a better as cast part from that data but then I would have to pry it from Jim's hands not to mention that right now we arent quite in the manifold business.....but we are getting there  Cheers, Tony |
