intake question!!!!!!!!

Looking for a single four, 4150 style intake for my jet boat, dont care about bottem end or mid-range, would like an intake that makes all its power at 5000 rpm or higher, thanks!

What heads?

dove's I currently have an offy port o sonic, domi flange with an adaptor on it and it is ugly inside.

A victor with a port mismatch. Or a trick flow track heat for a better port alignment .

A few years ago, I changed from a Port-O-sonic Offy that I had opened up to CJ size...to a matched Victor, and saw very little difference. My Offy was also "Ugly" inside from a design perspective, but was made as big as possible and the plenum was also opened up a lot. I was running ported D2s with PME highport plates on the exhaust and a 1050 Dominator at the time (514 mill).
Point of the story....maybe your Offy is not as bad as it looks...
The guy that I sold the Offy to still talks about it being a great manifold. Some of the newer tech ones may be better though. I have very little experience with those.

X2 Keith. The one I had worked great.

I would use the Trick Flow "Track Heat" intake manifold.

can I grind the clover leaf pattern out of it? or convert it to a 4150 mounting flange?
