Which intake/carb combo
#1
Yes, I know there are 6.23 million combinations available. My set-up is for weekend burnouts with a couple trips to the strip, weekend driver, with decent street manners. I've got a 73 351C 2V with FMX, and I need to get some gears for the rear end. I have the CompCams XE262 with .218 - .224 duration, .513/.520 valve lift, 1400 - 5600RPM. Using a carb calculator I learned about in the WFQ, I believe a 600CFM carb would be the best match. But which one? Ease of installation and ease of operation are most important to me at this point.

Now, dual plane or single plane manifold? I've heard good things about air gap intakes. Anyone have experience with these set-ups on a 2V Cleveland?

All suggestions and comments are welcome!

Doc I believe the Edelbrock performer manifold is the rite choice for a mild street motor along with a Holley street avenger carb. The throttle cable and trans kick down rod attach to the Holley with ease. The performer manifold has all the vacuum ports as the stock manifold. With the Air gap manifold their mite be a clearance issue with stock flat hood. The performer is a dual plane that makes good power from idle to 5500 rpm which is good match for the cam. Mike

I have the 351 2v fmx. I went with the performer dual plane and 600 edlebrock. comp cam 494 valve lift, 218 duration,1 5/8 long tube headers.325 trac-loc. This may not be the best setup but what an improvement.I gained a lot of HP. My car was a dog before the rebuild.

If you don't do a lot of highway driving, the performer rpm and a 3.50 gear with the 600 cfm carb of your choice. If you want something more friendly on the highway then a regular performer with a 3.00 gear.

Great advice, guys. That helps narrow the choices considerably.

Mark I know what you mean about her being a dog before the rebuild. Mine was more like a walrus. Tongue Big Grin

I'm running the Performer 2v and a Holley vac secondary carb similar to the 670 Street Avenger with the stock converter and 2.75 gear ratio. I'm pleased with the combination.

Alright, folks, I've decided on the Edelbrock Performer intake #2750 coupled to a Holley 80457 600cfm carb. I've read several articles that recommend that combination, along with your recommendations here. I'm ordering it first thing Monday morning, so if you have some more input, post it now. Smile

I believe those are two GREAT choices for you, Doc and that you will be very happy based on your posted desired goals and what you had when you startedSmile.

Sometimes folks (including me) forget what they intended to "build" when they get into it - - You have apparently stayed "true" to your desired outcome.

I am IMPRESSED!
