I found a vintage small block chevy scorpion intake from a friend. I thought it might make a neat piece on my 55 chevy gasser dream car.(Im gathering parts but dont have the car yet, 327's, 283's a muncie 4speed period correct) Are these intakes similar to gap rpm?. I'd proabably use it with a 327, #186 double humps, and a new comp cam from the thumpr series shifted via 4 speed. any suggestions? or should I just get the newer style intake?
It's a 70's piece and they worked surprisingly well. A Scorpion and Angle Plug heads were THE hot set up once upon a time. I knew a guy back in '78 or so that put one on a 283/PG in a '63 Chevy PU with a WCFB on it. We all told him he was nuts and it would never run. It not only ran but ran pretty decent, I think the small carb, 2" 4 hole spacer under it and the 4.10 gears helped. If you have it run it, it would probably like the Thumpr cam. You can always fine tune with spacers and/or a plenum divider. There were definitely worse intakes.
I had a scorpion II intake for a small block chevy, we ran it on a 400ci/350 crank setup 383 and while it was not the frendliest street manifold, it was a 2,000 to 7,500rpm monster for racing. We ran a 780cfm dual feed holley, 1inch spacer and a nitros shot with a 300/500 lift cam, it was off the chain! If you wanted something for a daily driver I would not recomend it, really too hot for the street.
I know you didn't ask, but I'd recommend from personal experience that you look at other cam options. I had the big thumpr cam and it sounded snotty as hell at idle but drivability suffered. In about a year I pulled it out and put a comp XE268h in. It sounds better in my opinion and performs much better. Not as rowdy sounding, but the thumper didn't sound good to me. Sounded like it was popping out the exhaust like a bent valve on every cylinder when they fired to me. The intake is older technology and you could find a much better performing and appearing intake if sticking to a traditional look/theme is your goal. It will work well just a little more suited for a higher rpm range.
Its basically a victor jr......the runners are a little different but performance/characteristics are about the same - ran one in my 55 chevy on a 1968 MO 302......good intake - but might be a little "late model" for HAMB period correctness....
I used one of these on a 302 CI SBC in an old-school super modified. Worked great when you kept the engine 3000 RPMs and up on dirt tracks.
I had a similar Holley Strip Dominator intake. Pretty much the same thing. I had a stumble, when I stomped on the throttle that I never really cured. I blame the intake, but if you roll into the gas pedal, it was great. I say run it.
A custom ground cam from like Clay Smith for the exact combo you are planning will net the best all around results. It is free to inquire.
They are a higher hp vintage intake. Step up from the original Torker. They always command good $$ at swap meets. Polished they look great on street, the Scorpion is added bling.
Interesting . The guy who resurrected this 2009 thread in 2015 joined and made his one post the same day, never to return. The guy who then resurrected it again this year, also his first post. I this subject on a 6/7 year first post cycle?
