I plan on bypassing, or removing the water box. It has to kill some hp. Removing it will be a biotch, it's glassed in. Bypassing was easy 2-4" 45s, 1-90 about 12" 4" fiberglass tubing
Hope to fire up this weekend to see how it sounds

SO N/A its nearly same as mine less compression and more CI, not a home run over mine, oh well I am up and running all last season and so far this one, it is what it is... F Bob...

.. I keep wondering if there's something else going on we're not catching.. (ie: cam timing, rocker geometry. etc..)

I DO have 15 cubic inches on you (555 cid) but I think about a full point less compression (I'm at 8.6:1)
I believe we have the same heads.... AFR 325 cnc..
My cam is a bit smaller .644 in .629 ex. Lift. Duration 239 in 246 ex @ .050 as it's spec'd for a blower
and we made about the same power N/A.... I dyno'd mine wet with Eddie Marine exhaust...


Maybe it's because I essentially built my engine in my living room, and as ya'll say, the cam was designed at a kitchen table.. LOL


P.S. Congrats to the O/P on an awesome build :party-smiley-020:


I'm curious as to cam design for a blower and dynoed without.

I think Tims was a 241/246 112 lsa cam if I recall. Boatally, a 239/246 ? What lsa was it on?
