Any dual plane intake will perform better with a broader horsepower range if you take the center divider down to 5/8" above the upper floor. That increases total air/ fuel volume to all cylinders. 1994 Undercover Chassis 125" altered stack injected big block, soon blown and injected Member of The Torque and Recoil Club

Yes, they are cast iron OEM and they LOOK stock and untouched... classracer.com will help you locate someone.

Plus, I'm sure Bill would rather not get caught cheating and then not allowed to pull with this organization for a year. I don't know how many times I've heard "That Dodge runs pretty good, he must be cheating". Why give them any more reason to believe that. Cubes will be under 470.

Seems to me when the rule requires iron manifolds, that the truck should have them on, or go to another class. 93 W250 CTD getrag, Bosch 185 injectors, AFE air filter.

The rules don't say anything about stock cast, just cast. I'm pretty sure the majority of them are running non-oem cast iron. I saw the Indy cast iron heads, but their intakes didn't say whether they were cast or not. I'll start looking for the 71/72 intake. Thanks guys, definitely alot more info/replies than what I expected.

FWIW, when I truck pulled several years ago before everyone got stupid on spending ridiculous amounts of money to win a hundred bucks and trophy, I used a 70 model square bore manifold with the divider trimmed down and a 2 inch carb spacer on my 440. The iron intake is a B.S. rule anyway. Look at all of the chevy guys running square port heads, probably Merlins at that, and adapting an oval port cast iron intake to work with the heads. To my knowledege, they never made a square port BBC engine with a iron intake. As far as not cheating and winning, It aint gonna happen. Thats why I quit. EVERYONE cheats. 500+ inch motors on nitrous, hidden vac pumps to pull vac at idle, blocked suspensions, pro fab transfer cases, the list goes on and on.... 392 gen III hemi on E-85 727 trans Dana 60 10.02@134

It makes a huge difference because one way it makes the class all about the intake manifold and the other way just rules out expensive hand-fabricated intake manifolds. The rule about iron heads is a good cost-reducing one and allowing any aftermarket cast intake is reasonable since cast manifolds are cheap. Restricting contestants to OEM Iron intake manifolds could really take the fun out of it. I can understand if there's some confusion about the terms 'cast' and 'cast iron' because some people use incorrect or incomplete terminology using the term 'cast' when they mean 'cast iron' or the term 'alloy' when they mean aluminum (that one is really annoying). A set of iron max wedge heads or 440-1's with an indy intake should support a lot more than 470ci. Quote: I'm sure they'd just make me pull the carb to check with a magnet if questionable.

You could run a stock intake on the indy heads port match a bit closer to the Max wedge size the step up at the heads does not hurt as much as the other way. Chebys have some huge cast heads for their big blocks so a set of 440-1 C's should be fail play! Last edited by Dodgem; 01/05/13 02:23 PM.

Here is a pic of the intake manifold from my stock Dodge truck 75 440. Part # 3830733-2 and 05110 cast into it. I also have the same one on a 73 Dodge truck 440. When you all say 71 TQ manifold, are you not talking about just any TQ manifold? Is the 71 a taller/better manifold? Anyone have a pic? Thank you. 7534504-440intake.jpg (425 downloads) Last edited by bgilbert; 01/05/13 09:15 PM.
