thinking about replacing my stock intake and quadrajet with something newer/less maintance/ more performance. i am thinking of the 7161 Performer RPM with either a edelbrock performer carb (750 with elec. choke) or holley 3310. does anyone know if i have enough hood clearance using my stock ss hood (louvered, not cowl induction)? any suggestions/comments about my choices?

Mike, I'm going to take a good guess at this and hopefully someone else can let both of us know for sure. I plan on running the BBC Edelbrock Performer RPM #7161 also on my 427 '68 with an SS hood. I have 2 original GM 14"x3" open element AC drop base air cleaners. 1 is an orig. '67 Z/28 and the other is an orig. '70 L78 unit. I am going to run a Holley carb. I figure that when GM built the '68 L78 Camaro, they ran an SS hood, the L88 type hi-rise factory intake, and the open-element AC air cleaner. GM made this setup fit. I'm not sure, but don't believe that the #7161 Edelbrock is taller than the original L88/L78 intake manifold? Can anyone share any input?

height on the rpm is 4.45" at front and 6.0" at rear. not sure about stock. i did email edelbrock and asked them about the air gap (.25" taller than the rpm) and they said "It will be close, but is should fit." so i'm thinking it will, but if someone knows for sure please reply. i have the stock 14" chrome air cleaner on mine and would like to reuse it. (3" k&n filter). still trying to figure out if i want to go with a holley or edelbrock carb. which model holley do you plan to use?

I just recently sold an L88 intake and shipped it to Florida. I wish now that I had taken some measurements. I have a 750 Edelbrock/AFB manual choke carb. I ran it on my 2 ton tow truck for awhile. It was the only new carb. I had laying around. I like them (was too big for stock 350). It's a good carb. but I think on the Camaro I will have more clearance with a Holley. The stock AC open element air cleaners will not work without a riser on an AFB type carb. I have Holleys from 650-850cfm. I have mostly all double pumpers and 1 Vacuum secondary. My car will be running a Super T10 4 speed trans. I wouldn't recommend a double pumper carb. with an automatic trans. for an everyday driver. The 4 speed would be more forgiving with one. I will most likely run a 750 vacuum secondary Holley. I think it's a 3310-2? The engine is going to be kinda mild. It will be about 9.2-9.5:1 compression, mild cam, headers. I have a great set of heads, 049 casting, 2.19&1.88 Manley stainless valves, cc'd,
flowed, bronze guides, p-c seals. I figure the heads are good for 50-75hp. over a stock pair. I have a new Milodon low profile 7qt. oilpan, diamond stripper windage tray and extended pickup. I have been saving these parts for years for a '68 Camaro, and just found the car a few weeks ago. I figure it should be real easy to make an honest 400+hp. If that's not enough, I have a NOS 250hp.

I have 69 that had edelbrock performer carb, and a performer RPM. I had a stock air cleaner and it cleared fine. I then put on a
one inch carb spacer and a holley carb. I used a tall K&N with a drop base. Still clears stock hood, but very close. Hope this helps

Before I switched to a cowl set up and a different motor, I was running an RPM and a 3310 under a 69 SS hood. Cleared fine with the aid of a drop base K and N filter.

I currently am running a Performer RPM with a Holley 4150 and a 1" spacer plate. It clears my SS hood without any problems.
