Its EFI 4500 series for a dominator carb. Pictures clearly show difference between that one and 4150 series carb intake.
Yes but it is a EFI intake. You have to block off some stuff. The carburated version is no longer made, but you can adapt the EFI version if you make block off plates. BTW, I would have a hard time kicking down 515$ when those things were on clearance a few years back for 180$, I just missed out. How do you think Tom got all those. Still 400$ is better than 515$. There is a 4150 Victor for around 270$ too. You can convert a 4150 intake to 4500 yourself. I converted my 4150 Warrior to 4500. You need aluminum 5/16 bolts, JB Weld them in the bolt holes, re drill and tap them for 4500 and do some grinding/machine work. Mine had been that way for 15+ years, it works.

Thats why I am kind of leaning towards Northwind intake. But actually all youd have to do is put plugs in EFI but a 4500 carb will bolt to it, all would have be done is remove Cloverleaf. Or so my engine builder says. Hes familiar with both heads, he had a set from Kauffman that were supposed to flow 380 cfm. But on his bench they only flowed 355 @ .800 lift.

370 cfm heads, big 4500 carb, Victor and Northwind intakes !

64 Goat. Curious, what in fact is the proposed combination for all this ?

HP goals ? Intended peak power RPM ? Stroke and Cubic inches involved ? Proposed type of cam and how much intake duration at .050" ? Etc.

Really need a 4500 Dominator carb with low hood clearance, see my posts 17 & 18 here: http://forums.maxperformanceinc.com/...reet+Dominator

Dave Bisschop did it for me. Sitting under a work bench, make me a offer

Well you can give us a idea or desires. Stroke ? Cubic inches ? 5500 rpm engine or 6000 rpm, or 7000 rpm, etc, etc

Example, you certainly don't even need 330 cfm High Port heads with their HEAVY valvetrain mass for a 600 hp 6000 rpm combo. A simple set of 310 cfm Edelbrock heads with a 254 degree solid roller cam and a Torker II intake with a good 4150 carb will make 600 hp at 6000 rpm with a 4.210 stroke. If 600 hp does not suit your needs then more conversation here would be helpful.

A dyno proven 455 combo by Ken Crocie....

Using Edelbrock heads with a nice clean up only, about 288 cfm at .600" lift on the intake. Pump gas combo with 10.2 compression. Performer RPM intake with a 850 cfm 4150 Holley carb. Used a big Comp Cams 268 at .050 degree hydraulic flat tappet cam with Rhoads Vari-Duration lifters and Harland Sharp 1.65 rocker arms that netted an actual 0.606-inch lift at the valve. This would mimic the lift curve of a traditional soild roller up to about .600 lift. With valvesprings set up at 130 lbs on the seat with 320 pounds open pressure. After running on the dyno they eased down to 122 lbs on the seat.

It made 572 hp at 5900 rpm. With a 850 Demon carb it bumped up to 588.5 hp at the same 5800 rpm. And with 603.7 lbs torque at 4300 rpm. It was still making 575 lbs torque at 3500 rpm !

Factory 4.210 crank, 6.8 Eagle rods and Ross pistons.

Another combo for conversation around the coffee table !

473.5 cubic inches, 578 hp at 5,500 rpm.

312 cfm Edelbrock heads with a 242 degree hyd roller. Victor intake and note the carb used.... no big 4500 Dominator ! Victor intake too tall... as discussed here us a Northwind.

My previous combo ....

4.210 stroke / 462 CID / 313 cfm Edelbrock heads / Performer RPM intake / pump gas street engine

Dyno results: 589.1 CB Torque @ 4400 rpm and 580 CB Power @ 5800 rpm

Quarter mile: 1.60 60", 10.88 ET at 124.28 mph

In our horrid Texas summer heat it would often run low 11s when the track conditions were so so.

90/10 shocks on the front and no sway bar in place

A-1 8-inch 4200 stall converter

TH400 transmission with manual valve body / shifting at 6000 rpm

3:73 gears

28 x 12.50 M/T ET Street DOT tires

Race weight: About 3750 pounds

For the street I used a Continental tight 10-inch converter. And the sway bar was on.

Thats not 572HP. I was running 12.07 @108MPH with unported 96 D ports with a .550ish SFT through 75$ 1 5/8" cheapo 4 tube headers.
