Torker vs. Performer351 4-V

I have the Performer on mine and I have always noticed a lack of power (falls on it's face) above 4500 rpm. Please advise if you see a definite increase with the Torker.
Thanks
Lar

I PUT A TORKER II ON MY CLEVELAND, IT'S THE OLDER "CLOVERLEAF" STYLE, BUT YOUR ENGINE WON'T KNOW THE DIFFERENCE. IT IDLES PERFECT AT 1000 RPM, RIGHT WHERE I LIKE IT FOR TAKING OFF SMOOTH AND EASY FROM A DEAD STOP, NO BOG, NO HESITATION! I DON'T KNOW HOW HIGH IT WILL REV, THE HIGHEST I'VE GONE IS A MEAR 5000 RPM, MAYBE. SINCE I WANTED A "HIGH RISE" INSTEAD OF A "LOW RISE", I TOPPED IT WITH A 1", FOUR HOLE SPACER, TO ADD VOLUME BUT MAINTAIN INDEPENDENCE OF SIGNAL. THE TROTTLE RESPONSE IS EXCELLENT! 2" MIGHT BE TOO MUCH, I DON'T KNOW. IT PULLS PLENTY STRONG, AND HAS TONS LEFT TO GO. I LIKE TAKING CARE OF THIS MACHINE, I SHIFT VERY SLOW, CAREFULLY, AND SMOOTH! I DID ALL MY HIGH REVING, SPEED SHIFTING, AND RACING IN MY 400 TRANS-AM, IN MY YOUNGER YEARS, WAY BACK IN THE MEZAZOIC ERA! SO YES! GO WITH THE TORKER II! ALL THE BEST, MARLIN.

I have a Torker intake manifold installed on my modified 351-C in my Pantera. Basic engine specs are as follows: Bore is .030 over stock, stock stroke, hydraulic roller cam installed (.550 lift @ .050, 222 deg. intake, .585 lift @ .050, 232 deg. exhaust), 9.5:1 C/R, 2.25" dia intake valve, stock dia exhaust valve (Tulip Head from B.B. Chevy), ported 4V closed chamber heads ('71), B.G. Gold Claw Carburetor configured for 725 CFM.

This engine configuration is good for 6500 RPM, idles @ 650-800 RPM & runs like hell everywhere in between. There is no sign of power falling off even @ 6500 RPM! Someday, I'll try a Rousch or other high-rise single plane intake, but at the moment, I'm very pleased with the current performance. Good Luck!

I'm seeing the same thing with the performer, no top end. I guess it's time to change manifolds again.

Guy,
Your car looked great this weekend!I would go with the Torker if you want to keep it under the engine cover.I am VERY pleased with my FunnellWeb intake but it definitely won't fit under.

A few years ago someone went to all of the work to precisely measure their � mile acceleration performance with the Performer and then removed it and did the same test with the Torker. Sounds like it was a lot of work but they wanted to know for sure what way to go with the manifolds. As I recall the difference between the two manifolds was insignificant. He posted the results on the de Tomaso email forum. You can search the forum database from this page http://realbig.com/detomaso/ You do not need to be a forum member to search the database but if you want to participate in the interactive forum you register at this link http://realbig.com/mailman/listinfo/detomaso. It�s a super good resource for Pantera owners or owners to be, probably a little more technical than this site but like most owners I subscribe to both sites.

PS
I found the info at http://realbig.com/detomaso/1999-02/526.html The Performer with a small spacer came out on top!

Also pleased with the Funnelweb. Nice top end. Works at low end, but that's not where
the action is for this setup.

If you look closely at the specs for the torker and performer the names are reversed as to what they are, performer has longer runners thus better for lower rpm.

Mark,
The Ford Motorsport Nationals at Maple Grove.
It was a GREAT time.There are some SERIOUSLY fast Mustangs there.I saw several 1500 to 2000 H.P. small block Fords there!

Will do.
