|barnym17||The weiand will work just fine for ya for now.It is a good intake I would be willing to bet due to it's runner size you will be hard pressed to feel a dif. down low and just may find some power when on the hammer.|

You will give up significant low end grunt right wher you do the most of your driving. Why not address what ever is really causing the intake manifold leak and use the Dual plane manifold.
Installing a plenum divider in the single plane manifold will not restore the lost low end power compared to a dual plane. If the motor is mild you should be using a dual plane with a fully divided plenum anyways.
Fix the intake you got. Or get another dual plane manifold.Not the cast off old junk your machinest has hanging around that he wants to unload on you. Don't assume it's the intake causing the problem. The heads intake mating flange could be out of wack also.
My Professional products crosswind intake manifold fits like a glove and makes big power. (I didn't even need to port match it to my heads) I've used both edelbrock and the PP on the same motor even.
The edelbrock RPM air gap has a more pleasing appearance of the as cast outer surfaces, but the fit and machining is the same.

This particular intake is not that bad for an old single plane, but make sure you use it with the divider as it will help low end a lot. This intake(Wieand Accelerator #7546 w/divider) has been out of production for close to 10 years, so it may not have enough material to cover some of the newer +.100" raised intake ports. Check before you just bolt it on. If it will work, I would use it as a test to rule out head problems and then replace it with a new piece geared toward your build if the problem is solved.
The PP Crosswind, and the Typhoon(dual planes), come up in a lot of problem threads around the web, strangely the PP Hurricane(big single plane) hardly ever. Have used the Hurricane without problems, but know a friend that had driveabilty issues on his street rod using a PP Typhoon dual plane(non air gap like an Performer) and took the polished PP intake off and put the Performer back on and the hot start and sputtering problems went away.

By chance will using a plenum divider plate help out some in my application ?

Intake swap: dual plane airgap to single plane ?
Having a potential issue with my professional products crosswind (clone of edelbrock airgap); it is a a dual plane air gap design. Going to swap it out for a used Weiand which I was told has an open plenum with divider plate...I believe this is a single plane. Looking up the Weiand intakes I beleive it is the X-celerator (also told it has the accesory holes for the A/C bracket); this is the only intake I can find that matches thes specs...also this intake is "free".
Question is I rather not keep swapping intakes and if this solves the problem, than great !! However I am concerned that I will sacrifice some low end performance. My current setup is 383 stroker, Holley 750cfm, Comp Cams XE262H, 4 spd with 3.08 posi. What sort of performance decrease can I expect changing from a dual plane air gap to a single plane ? Thanks.
