In pics 1 and 2 you can SEE how the ports run to the flange before the billet halves are welded together. He is also in the process of making a "drop in" 6.7 version.

Bit of bling,hopefully give a bit more HP(as per the posted dynorun sheet on the there website), cool EGT /better flow/quicker spool---similar to the 2 and 3 piece designs out there but in one piece.It may be tuff to tell cause a HTT 62/65/13SS will go on at the same time.DW

I am just doing the manifold. That's it. I am looking for the torque gain at 2000 rpms where I tow. On the dyno sheet you can see an increase of 143.24 RWHP and 378.55 RWTQ at 2000rpm's. I do have a the Hamilton 188/208 cam so we will see what I get.

Really?I can barely read the #s but a manifold aint gonna give you anywhere near those figures.Maybe the decimal points are off,like 14hp and 37 tq?

Thats the way i'm thinking too-----but any little gain is better than stock manifold.

Total HP/TQ gain is that low. I am looking at what is under the curve, the usable HP and TQ. I don't use my truck a peak HP and TQ.
