are there any companies out there that are building true dove port tunnel rams?

i am trying to put together a new manifold for my turbocharged and fuel injected 523. i have been running a victor set up for FI and matched it to the ports with epoxy and i am haveing trouble keeping the epoxy in place. i have tried a few different kinds and none of it stays put more than a couple months.

i would like to try a tunnel ram because it has longer runners which would help in torque production down low off of boost. a dual plane is out of the question.

it seems that most of the manifolds available are cj port sizes. i am leary about running one of those due to the extra port volume and lower velocity of it.

the operationg range of this motor is 800-5500. on the top end, the boost will compensate for lack of port volume and cam duration to an extent. boost will be building by 1800-2000 rpm and will be peeking around 15-18 psi.

this is all in a heavy 4x4 truck that gets used for mud drags and bogs. the low speed portion of the power curve becomes critical on the trails and rock crawling.


thanks for any input and feel free to ask any questions

I think you need a custom sheetmetal T/R if it needs a uniform small C/S

i have put a sustantial amount of though into this. in the future a may build one. for the moment though, i need to spend my time else where in the project. i have the ability and resourses to build whatever i may want but it all takes time.

I'm pretty sure that the Weiand piece is DOVE port sized out of the box.
