Performer 318/360 intake

[67FormulaS_273HiPo_4spd]

I remember reading in an old Mopar Muscle magazine some years ago, that a 318/360 Performer intake with a simple port match to 360 intake port size and a one (1) inch open spacer worked almost as well as a Performer AG intake on a standard stroke 360 combo (400-450HP) to 6,000RPM. Almost... I have a 318/360 Performer intake on my 273 Commando mill in a '67 Barracuda 4-speed car. Works great in this application, better than the original low-rise cast iron 4BBL single-plane intake.

It would be great if you could find that article and post it.

it running out of huff at 5K was probably the combination of parts: the 600, the cam and the manifold would all be done about then.

the new manifold and carb will allow you to stretch it's legs a little more-- at least until valve float-- but whether you actually make any more power would be hard to quantify without some type of testing.

I agree, that is why I wanted to "open it up" a little with the slightly bigger cam, carb, and manifold. It has Comp 901 springs. I am hoping to make a few more up top also. Revving out to 6k I think will help with my wide split 3 speed manual. Its an A230 so it winds up quick in first but then the shift into second drops the RPM a few hundred farther than I would like. I'm sure AJ could do the math. I am going by feel. with my current combination the torque is good but I just feel it has more left at the top. It's easy to wind it out with the manual transmission. So yes, I would have to do some real scientific testing but all I have is my butt dyno haha.

I'll look through the stash of magazines at home...

the 3spd is a real mood killer, that gap has bested many a man (myself included). go searching for more power up town and wind up sucking the bottom end out and all of a sudden that 1-2 shift leaves you flat footed at the other side of a wide intersection.
