Is your car ready for another 80 hp!

I'll make sure the car is ready just have to figure out if the driver is ready Soooo, see below for my current best et and then figure another 80 hp in a 3250 lb car and what et will I gain? Maybe 2.5 tenths?

"I see that Indy sells a six pack lid for this intake. Anyone try that baby yet? Maybe I need to make the call to Russ and Ken and see what they think about a six pack setup on this motor. It doesn't seem like the six pack setup has enough airflow to make 700+ hp but who knows. Rossi used to make some serious power years ago with those carbs."

Has anyone ever dyno'd the Weiand sixpack tunnel ram that the Super Stockers use? I'd like to see how it compares, since the factory intake runs out of steam. I'd offer mine for a dyno run, standard size ports though.

It looks like I'll be back on the dyno with the Indy six pack setup in the next few weeks. Won't know for sure until all the parts show up.

I don't think I'll test a std port six pack manifold since I have the MW heads. The std port setup might bolt on (not sure that the gaskets will seal) but there would be a decent size port mismatch that would put a kink in things.

ARI - You can't mount Holley carbs that have metering blocks in line but you can mount up the ones with metering plates. Here is a pic that I took with a couple of Holley 1850 carbs mounted on to the manifold. You can also turn the carbs sideways and then you could run twin HP style carbs.

It would be a real pain to tune the dual Holley setup like this though since you would have to remove the carbs to take the bowls off. And, you have to change metering plates or drill them since there isn't jets. That would get really old, especially when you're trying to sort out some cross jet issues.


One interesting data point: This combo here with the dual 1850 carbs weighs exactly 30 lbs more than a Indy 440-3 intake with a 1050 Dominator.

It looks as though there may be enough room left between the carbs to use a metering block in the secondaries as long as you stayed with the side hung float bowl. Just like the six pack set ups. Look at the mechanical carbs, they use a side hung float bowl and the rear fits with a metering plate. As for jetting, yah, it would suck to set it up but it's very doable.

BTW ... great photos Andy!!! you should do some side work for a magazine

andy, i believe ive seen replacement metering plats that accept jets

its quick fuel part, heres the summit link. they also seell them for center hung bowls

In the picture it looks like a secondary metering block would fit on that front carb but it actually doesn't. I tried it and you would have to use a press fit to get the carbs to fit.

But, there is non particular reason why Indy couldn't spread the carbs apart by another 1/8 or 1/4 of an inch. These manifold tops are machined on a CNC vertical mill and there isn't any magic to the exact carb placement. So if a person wanted it done that way I'm sure you could work with the guys at Indy to get the carbs moved apart.

So did the Indy Intake really make 80 more horses over the new Mopar Crossram?????????

Yes, that is basically correct.
