I move a bunch of these, especially to the guys with big inch small blocks:

So what are you going to end up running?

At the moment the 4150. The Dominator was on loan. The Dominator appeared to carry more torque throughout the RPM range.

It's all good. Everything is open for discussion. And real information is always good information.

I saw you had these on another thread. How much? Going to need a couple if I end up with sv565 intakes.

When we swapped to the 4500 style intake we used that style spacer(not adapter). Picked up 5 hp going from no spacer to 1 in. Picked up another 5 hp peak going to 2 in., but not quite as much under the curve. Overall 1 in. was probably best. Will try another combo when they go back on.

That is a 4500 carb to 4150 intake adapter/spacer.
Part #SS4500-4150-2.
