First time post here guys so be easy on me. Gonna be doing low deck stroker build for my street ride. Was wondering what heads can I use. That will allow the use of the Indy DP on my low deck.

I use Edelbrock RPM heads with cnc max wedge ports done by Muscle Motors.

Welcome to Moparts!

The MW port allows you to use the Rb intake on a Low Deck? I seen you can use the RB intake if you use Stage VI heads. Is this the only heads that make this combo possible?

Yes, the Stage VI heads are the only way to use a RB intake on a low deck. But that is really the wrong way to make a decision on heads. The Indy DP intake isn't nearly good enough to offset the pain you'll have with the Stage VI heads.

I'm sorry, I forgot the dual plane was only available for the RB. I use the Indy 4150 single plane on my street car. It has PLENTY of torque with pump gas compression and a small flat tappet solid cam.
It's a 500" low deck.

I totally agree. I'm just starting to layout this build. Not sure if will have the hood clearance with a Eddie RPM manifold. Wondering what options I had on the Low Deck head wise for the Indy DP. Looking to do the 512. Wanting to build a torque monster for what I call a Pro Cruise. 62 Dodge 880 2dr hardtop. Thanks for the help guys. Just be ready for some potentially dumb questions.

How big C.I. and how much compression and which type tranny and weight of the car? Probally not one size fits all combination on that intake

I'm thinking alum headed 10.1 10.5 comp Hyd roller type build all in by 5500. Dodge specs list the car I believe at 38 hundred something LBS. I'm thinking more like 4000 big car. Anyway 727 with a 3:00-3:23 gear. That depends on what tire I have under it. Really like to be in the 600 lbs torque mid 5's Hp all in at 5500. If that is possible. Anymore TQ HP than that would be gravy.

On your deal I would forget the Indy dual plane and look hard at the M1 dual plane with a Thermoquad carb. That or the Eddy RPM dual plane low deck with a Thermoquad That is with 440 size intake ports, if you want Max Wedge size intake ports then your choices are very limited, that car woud be perfect with the last generation old long cross ram dual quad set up with a set of eddy RPM heads on your motor, looks killer and runs like stink

A low deck 512 with Edelbrock heads (or maybe the new Trick Flow heads) should work just fine. There are several low deck dual plane intakes that you can use. You should have room for a Performer RPM but you won't have room for a tall air cleaner or a carb spacer. You could put a Max Wedge type scoop on the car for a little more room and some cold air. Those scoops look good on that era of car.

Yeah thinking seriously about doing the Trick Flows. Are the single plane intakes lower than Eddie RPMs intakes. Probably not the ticket for heavy car low stall 3:23 geared street duration hyd roller pump gas engine? I think I just answered my own question. LOL.

The most common mistake I see is guys building street engines with race parts. Almost everyone gets sucked into the "oooh, that is cool" and ends up with mis-matched parts that don't really work very well.

A 4000 lb street car with high gears isn't going to want big heads or a big carb or a big cam or a single plane intake. Do you have a copy of my BB Mopar engine book? It has a chart in there that shows you where the torque peak will be depending on cubic inches and port size. Std port heads on a 512 short block will give you a torque peak at 4000 rpm. If you have good heads and everything else is working just right then HP peak will be 1000 to 1500 higher than that. So if you build it right you should have about 600 ft-lbs at 4000 rpm and then 500+ hp at 5200 rpm or so.

You do not need a big cam or carb to do this. A MP .528 will work and so will a 750 DP or an Edelbrock 800 carb. A hyd roller will also work fine. I'd use the Performer RPM if it fits, if not then a Performer or a M1 dual plane. Don't make it harder than it needs to be and stay away from the race parts.

Thanks for the replys. I will order your book. For my 512. Would you recommend Molnar crank rods and pistons. Or is there a better route in your opinion. Don't wanna break the bank but don't wanna buy junk. My stuff doesn't have to be perfect but it's gotta be right.

Sure, Molnar makes good stuff. For a 512 you typically use a 4.25 crank with 2.20 rod journals, 6.535 Chevy rods and a 1.32 CH piston. Lots of people make a 1.32 CH piston so it is just a matter of figuring out which one you want.

You'll need a big dish in the piston in order to keep the compression down so you might have to buy a semi-custom piston. You'll need something around 15 to 20 cc dish if the piston is zero deck and you use a 036 MLS gasket.

The Indy dual plane should be pretty close to a Performer RPM in height .

I have a low deck 512 in my '65 Dodge Coronet and it fits under the stock hood. I'm using a Performer RPM intake, Holley carb and a tall air cleaner. But it is too tight to use a 1" carb spacer.

Yeah I did rough measurements and I think the RPM will work no problem. Once we get the front suspension started I will know for sure. I will mock up a spare motor and see. But it looks like I may even be able to use a 1 inch spacer. If you think it would help performance wise. The goal is drive it anywhere. Hit the strip once or twice a year and footbrake the boat into the 12s. Could be asking alot but will see.
