Post intake recommendations for 302 Chevy?

I have a 1968 chevy 302 in my 1969 camaro. It has all of the origional parts except for roller tip rockers. Double hump heads, 2.02/1.60 valves, the offroad special Mechanical - 257/269 intake - .493/.512 exhaust camshaft, 11:1 compression, hooker headers, 750 speed demon carb, msd billet distributer with 6AL box. I am running it with a saginaw 4-speed for now. I currently have a dual plane performer on it and I know that it is not anywhere near its full potential with this intake. I am fine with a single plane intake, I have been looking at the Victor Jr.s and Torker IIs. Do you guys have any suggestions. Remeber the major horsepower range is between 3500-7800.

Thanks,

ELi

Street only. I have been known to go to the strip once a year. Will the Victor Jr. be hard to street?

If you are running in that rpm range,a single plane would probably be your best bet,that puppy must wind up pretty good.I built one for a 83 Z-28 with a 5 speed and had nothing but a good time with it.

If you want something like what was on the original, the aluminum dual plane intake that is currently being shipped with the GM prefrormance Parts crate engines is a direct copy. FWIW, the 302 never was availiable with roller tipped rockers. For street driven use the dual plane is your best bet.

I agree with Vince... Just because the listed effective rpm range on a dual plane is up to 6500rpm does not mean it wont go higher... But on the street bottom end is a major concern... Dual plane factory style intake and drop to no more than a 650 DP, that 750 flows more like an 800-850 anyhow and kills that small cube engine on the low rpms...

302 intake

Dear Sir I Would Go With A Victor Jr. Intake.I Have A 302 In My 67 Nova With a SupperVictor On It And It Is Very Streetable. Only Because Of The Short Stroke. It Revs Faster And Gets You To Your Power Band Faster My Car Works Well From 1500 To 8500. And Is Very Steetable No Problems

I would stick with the performer r.p.m. or performer air gap. You would'nt probably be disapointed with the torkerII, another alternative is the g.m. performance parts highrise cast iron dual plane intake. it's a drop dead copy of the z-28 intake with a 1/4in. taller deck,and dual flange carb pattern. Just paint or powdercoat it grey, and you have a stock-looking z-28 intake! I HATE the zz4 stock intake with it's e.g.r. boss, and impossible to tighten center bolts around the e.g.r. flange!!
