For a 350 cubic inch motor (basically a zz3 bottom end and cam with vortec heads) which would be a better choice. TPIS miniram or the GM ramjet?

What are the flow number and rpm ranges for these manifolds???

That brings up another question, does anybody know the flow numbers for the ZZ3 and vortec heads?? Or where to find them??


Thanks

 

Its hard to say because there has'nt been a whole lot of testing done with this intake to see what it likes in a motor. The mini ram is an excellent intake, but it may be a little too much for your application. The MR usually likes a large engine or a smaller one that spins some serious RPM. With the relatively small ZZ4 cam, you may not be fully utilizing the capabilities of that manifold.

The ram jet may be a better choice, it has slightly longer runners (ram jet is ~4.25in and MR is ~3in) which may be better for your application, but availability of parts for the ram jet is not that great yet.

I have to go along with the Ram Jet.

It seems to be a better choice for milder applications, as well as the cutting edge in design.

Thanks, that is what I was leaning towards also.
How much different internally is the miniram from the LT1 intake. I think the runners are the same length, but what about port/chamber volume???


Thanks.
