Dual plane all the way. I made the same mistake almost 10 years ago.
Roadrunner, mild (emphasis on mild) 440 with a torque cam. Cast iron intake, exhaust manifolds, and a holley dp carb.
I switched to a 750 edlebrock (sold the holley) and when to a Mopar M1 single plane high rise manifold.
It never ran the same again. No low end torque, killed drivability. My embarassing 15 second quarter mile decreased to an even more embarassing 17. It was quite a learning experience. Go with a dual plane.

I think I can say that pretty much without question: The Edelbrock Performer RPM is going to be your best option. Its a high-rise dual plane that works real good on stock to mild street / strip motors. Only issue might be hood clearance (???).

Some basic aftermarket dual plane manifolds are basically the same as your cast iron intake, only lighter aluminum. Edelbrock performer or performer RPM (this sits slightly higher than stock) would be my vote for a stock motor. Or just my , since there won't much be a noticeable difference. Just put a 4 hole spacer between your iron intake and the carb for some added throttle response and some power gain? anyway you go, good luck. SP would be a step in the wrong direcetion though. eight

the single plane Holley Street Dominator was the BEST dual plane intake ever made

Look on ebay and the classifieds here for a used edelbrock DP4B intake. For stock heads it's all the flow you need. You won't gain anything except less hood clearance if you go with the performer rpm over the dp4b.

The holley SD is a good intake, but not for a stock 383 with 3.23 gears.
whatever you say..

Agreed, but we have all been through this, haven't we??? First its an intake. Next He'll look to buy a Holley carb. Then he might as well add headers. Hey, next let's take a stab at a Cam-swap. Then, how about some deeper gears.... I can't be the only one that's been through this!
So with that in mind, The RPM is an intake that will support his desires all the way up to and including an 11-second stroker motor. Since it also works well on stock-ish motors, might as well go straight there, now.

True, however for as long as he's running bone stock heads, he will never see a noticable increase in power with the rpm over the dp4b. Heads are the bottle neck at that point. The 383 intake shootout hot rod mag did showed exactly that, I think the dp4b even put out a few more ft-lbs(and at a lower rpm) than the rpm when tested on a stock headed 383 with a decent cam. I think the rpm was good for 5hp or something insignificantly like that. I suggest the dp4b because he can bolt it on and go, no issues with needing drop base air cleaners is a plus.

What makes you think it's a heat related problem?
when I start it cold it starts up fine and when I have a quick stop to make (10 min or so) the engine seems to take alot of cranking to start back up....(eng temp seems alittle high, plus enging compartment feels hot) and alot of the times I'll open the hood and take off the air filter to get it to resart because I don't want to wind down the battery
