Which Intake Manifold Holley or Typhoon?

[Rick 91GT]

Just to clarify some on the information in this thread.

The Holley is a great intake, fine for 302-347ci strokers, daily drivers or trailer queens, boost, N2O or N/A. I would only pick some of the other availble intakes over it do to the port size when ytou mate it up to a small head, with a larger head AFR185, Vic Jr, etc you would be hard pressed to find another long runner intake that will beat it.

NA 308's well into the low 10's with ported Holley's, power adder cars in the 8's with ported Holleys as well.

I started with the SysteMAX kit and felt no loss of low end or loss of tq with it due to the itake or heads, went 11.8's @ 116mph. I wouldn't have nay issue slapping a 75mm TB on a street car either...

If the budget is tight but you want something with better fit and quality than the Typhoon, you might want to look at the cast Cobra intake. It's not the top dog for horsepower, but it still works very good and is a little easier to install than the Edelbrock. Plus it you don't have to buy an EGR spacer, so you save some $$ there too.

It's a dead heat on these intakes...........

Hee is an AFM test with an AFM cam which tends to make power further up the rpm scale - shows the advantage of the Holley.........
