Edelbrock RPM intake

(1/3) > >>

73ss:
Has anyone out there had any experience with the edelbrock RPM Q-Jet intakes? Supposedly they are tailored to work with the q-jet. I scored one on e-bay for a BBC, Removed from a 502 crate motor. I guess this is the intake GM is installing on the 502 oval port crate motors. part #7164. It has a cut down divider. I brought this up after looking at Kelley555's thread & pics. I'm anxious to install after the holidays. I have an old-school weiand installed now that is good to 5500. The rpm is good to 6500. We'll see.

Compare the carb mounting flange to a Q-Jet base gasket.  Mine is not the only one to need some rework to clear the secondary throttle blades.

Wish I could help more; I bought the same manifold you have, but I've never used a Q-jet with it--have a few seasons with that manifold on the previous engine; and using an 850 vacuum secondary Holley.  Replaced the engine last year, and next summer I'll be playing with a Q-jet.

73ss:
Thanks for the reply Schurkey. You saved me some frustration. I placed a carb on & sure enough the secondarys don't clear. Makes you wonder how a manifold made specificly for a q-jet won't even properly fit a q-jet. This manifold was removed from a crate motor. Installed but never fired. Maybe this is why.

73 SS,this is about right for GM high quality,advertise it for a Q-jet & it won't fit. That kind of attitude the reason the 100 yr. old co. filed bankruptcy & Obama Motors began. Nothing can bring us down.That not the only mess up they had. Gm made the oem 400 block that were basically junk,had tons of problems with the blocks running hot,core shifts & steam holes,right. We shifted thru wrecking yards for years trying to find these blocks,fighting what the Gm engrineer's designed bad. Remember,the 2 bolt block's were the preminum junker,not the 4 bolt. Guess what,Gm had a 2 bolt block the Bow tie sportsman block same cast & thickness as the butt kickin,thick deck;thick bulkheads;Labeled HD on the block & casting # 184.Pretty close to the 4 bolt mains blocks,but cast with  2 bolt mains,excellent for a street build & a lot of cubes.You can go 427 ci ;4" stroke if your touche it with a die grinder.Try these cubes with the Oem block. Only Gm could advertise in their Chevy Performance manuel as a 4."00 bore(350 bore),so it didn't sell.Guess what,it's a misprint or somebody didn't had their head in their b-tt. The blocks will bore .060-.070 past the 400 bore of (4.125) & way thicker the the junk oem block. So you can have a 350 bore today & bore it to a 400 size tomorrow. They could have sold them all at a descent price. You want find this block in the wrecking yard. When Gm started to get in trouble,they sold all 600 plus blocks to a machine shop that scooped them up & resold them. What do you think the World & Dart block sbc  was designed after? Can we say !DUH!. GM employee's got too lazy to correct their many mistakes & be cause TOO BIG. !ATTITUDE & MORE ATTITUDE. I've been detailing my engine project in my Chevelle lately & has anyone noticed the quality of workmanship has definitely "gone to pot" in the hi performance industry.The quality of many accessories have to be redone or modified. I'm getting too picky in my later years. It's ashame of what's being offered as a finished product to the public. I feel like we're being invaded by the Chinese. Later Kelley

kelley555:
I just had to add this ,I apologize. The Chinese companies want our business so they can profit. The days of doing quality work & standing behind a product are simply over. Anybody ever notice how willing & nice a company treats once they get your money in their hands. ! Yeah right !Later Kelley
