edelbrock performer intake
750 holley vaccum secondaries
hooker headers

according to the compression calculator, should be around 10:1.

any potential issues that may arise?

thanks in advance

don't use the edelbrock performer!

single plane would be better

I would think the Performer RPM would be great for this combo?

Thats very close to the 383 I ran in a Dart some years back. I used the MP .484 cam on a 103 centerline. The heads were 452's that were stock with a little bowl blending and comp single springs. I used stock pistons and had 9.5 comp with the heads milled. It used a 750 DP and the Performer RPM intake which is a great street/strip intake. I used CPPA 2" headers (I had them so I used them) and 2-1/2 pipes. It was a 72 Dart done up to look like a 70 Swinger 340 and had 3.91 gears with a reverse manual V/B and a Turbo Action 10" tight 3000 converter. Ran a best ever of 12.31 @ 110 on a good day. Average runs were in the 12.40 to 12.60 range on hot days. Ron

Yes the rpm intake would be better, or the 383 version of the holley street dominator. 484 cam wouldn't be my first choice but if you do run that cam, make sure you have enough converter and rear gear.

What gears? read yesterdays comprehensive exhaust thread from yesterday (want minimal restriction from collector flange rearward). dial in each subsystem in the dist in order, initial/total/springs/vac adv (if used). As said a better intake

its 4.10 rear, and no converter...4=speed.
would i benefit from a single plane or would a rpm be a better match. i know its not a high power application, but i would like the best power i can get from it...thanks for the comments...will post pics soon. going in a duster

definitely the performer RPM would be the better fit for that combo. and i see no isssues with the old .484 purple stripe especially with the shift-it-yourself and 4.10's.

Close call on the single/dual but I gotta nod to a dual plane. yes the RPM is VG but it is also very tall (someone posted it's height) if it'll fit for you (maybe w a drop base). EDIT w more thought- dual plane

Better cams out there, but if yo have it go ahead and run it. try advancing it and it will work earlier. I'd also use a 750DP w/ a RPM or SD intake. I'd probably try a Comp Cams Cam CRB XE284H-10. It has more of a power band and will have better street manners.
