I have a 471 stroker with ported eddy heads by. mch and 590 lift cam 260dur at 50 10.6 comp It has a 6 pac on it now and I'm just tired of tring to tune it and my dyno guy said my intake was hurting me, so I thought I would go to a 4bbl and single plane intake.
I can get the holley for about 1/3 the money. The car is 90% street driven.
What do you guys think? THANKS FOR ANY INPUT EDDIE B

I've got nearly the same combo. Holley SD here and I love it. You may have hood clearance issues with the victor......not sure tho.

What kind of times are you running and what kind and size carb?
THANKS EDDIE B

The Holley is decent intake but I wouldn't run the Victor for a 90% street motor. The Performer RPM would be my first choice with the Holley SD or the Mopar M1 single plane my second choice.

No track time yet. Very strong street only so far. Carb is a Bigs 1000hp. I can keep it on the ground but I'm in Colo.....very high altitude.
I'd love to drive it at sealevel sometime. A bit of a pipe dream tho.

Hughes performance can port the six pac and squeeze lots more out of it!!

I've got the SD on my 500", and like it. First time at the track ever I went 12.00. 3975lbs. and street tires. I drive it everywhere. No complaints with that intake. A 950HP on top of it.

The street dominator is very easy to port and the shorter runners are actually an advantage on standard port 500" motors, Longs stroke with small ports doesn't need a long intake runner for torque and at high piston speeds the long runners can actually hurt flow compared to a shorter runner of the same cross sectional area. A little roof and wall work in each runner and a 1" spacer I've made them flow ~310cfm, enough for most decently ported 906 size heads.

I use the Holley Street Dominator on the 906 headed .030 over 440 in my 63. I really like it as it works very nice driving on the street at low rpm's and still helps it run mid 11's in street trim. Ron
