DP or SP aluminum manifold ... could someone possibly explain the dif between the 2 and what would be the best for a 69 383 (std bore flat top HP pistons W/ 3.23 rear) no racing , just cruizing the coast line Last edited by ngpSatellite; 04/16/10 08:43 PM.

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. eight Last edited by eightlitermopar; 03/31/10 01:56 PM.

Its a high-rise dual plane that works real good on stock to mild street / strip motors. Only issue might be hood clearance (???). LemonWedge - Street heavy / Strip ready - 11.07 @ 120

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 Mopar or no car

You won't gain anything except less hood clearance if you go with the performer rpm over the dp4b. Quote: the single plane Holley Street Dominator was the BEST dual plane intake ever made The holley SD is a good intake, but not for a stock 383 with 3.23 gears.

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. LemonWedge - Street heavy / Strip ready - 11.07 @ 120

ngpSatellite OP super stock N Joined: Oct 2007 Posts: 936 own private Idaho	the main reason I'm switching manifolds is that I still have alittle bit of a restart issue when I turn off the engine (gas station for example) and it is hard to restart (alittle embarrassing for a mopar guy )so I was thinking an aluminum manifold would conduct less heat to the carb... when I'm shutting the car off the temp is around 170 to 190 max so the car is not running hot.... I also have a spacer (1/2.. 4 hole phenalic)on it now. (edel 750)

Lots of times helps for quicker starting by unloading any loaded up gas accumulation. Clean it, if it's Dirty. Oil it, if it Squeaks. But: Don't fix it, if it Works!

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.

It's abut a 1/2 to a 1/2 inch thick. It's an insulator gasket.Also check your water flow. Excessive engine compartment heat soiunds like steam pockets in the heads.
