Will a tunnel ram fit under my 440 6 pack hood?

I was looking at the Indy 440-15. If not, what's the best dual 4 barrel intake? I have an Offy 360 that's been ported to match the heads, but it is supper low profile. Is the ModMan any good? I've read good and bad about it.

A tunnel ram will not fit, There is an edelbrock inline dual 4 intake that is a nice performance piece, but it only fits two eddy carbs.

This looks great and I was considering that one as a replacement but the way the carbs sit so close to each other, my nitrous plates and plumbing won't fit.

Really want to keep the 2 4barrel carbs... Any thoughts?

Modify the nitrous plates or make new ones that will work, Really no other options that I can think of.

Ditch the plates and go to port injection?

In considering a single carb intake. Which would be better for a street/strip 440 with ~9.8 to 1 compression, Crane 302 cam 512/540 lift, with use of ~200 shot of nitrous. M1 or Edelbrock Performer RPM?

And what size Carb? I was thinking to get something bigger than I have to have now as am ultimately looking to build a ~520 stroker for a replacement when this motor dies which may not be long from now.

Depends. How tall is a 440-15? What car? They also make a taller version of the six pack scoop.

I have a Weiand "tunnel ram" in my 1968 Barracuda with a standard six pack scoop. But I converted it to port EFI with a shortened six pack air cleaner. It barely fits. The EFI throttle bodies are shorter than a carburetor.

In the third picture you can see the air cleaner stud when you look through the scoop opening. There is about 1/4" clearance. I also added a picture of the six pack air cleaner when we were fitting the hood, we had to cut some structure towards the back on the bottom of the fiberglass hood to make everything fit.

Fitment picture...

If you are talking about an A12 hood scoop, this one fits as it was made specifically to be Superstock legal. Available in single 4 and 6pak only so you would have to built a 2x4 top for it.

OK, that looks AWESOME!! Where did you buy the tunnel ram pictured?

Thanks for sharing!

It been out of production forever. E-Bay, Racejunk or they turn up occasionally here but they have got stupid $$$.

I have seen NOS ones listed for $1500.00 and they seem to be in the $700-$800 range used on average.

Here's a link to Don Dulmage's website where he fabbed a 2x4 top for it.

Mopar part # P3690982

I bought it on E-Bay June of 2013. I also got kind of lucky, his reserve was not outrageously high, the auction ended mid day on a weekday, and there were no other serious bidders. I had been keeping an eye out for one for several years, they are not easy to find. Mine was new, I had the seller ship it to Bruce at F&B Performance who did the EFI conversion. http://www.fbthrottlebodies.com/

Bruce will sell you a brand new 440 6bbl intake converted to EFI in the same fashion. Should be no issue with hood clearance. But, this is not a tunnel ram. This is the EFI set up that is on the Year One '69 Road Runner 505ci engine.

The Weiand tunnel ram intake has runners tuned for a 440. The runner length is too long for a 500ci engine, unless you were building an engine for a truck used for towing.

EFI likes camshafts with more LSA (112-114) and good idle vacuum. Makes it easier to tune. Not impossible with lower LSA, just not as easy. I am looking forward to tuning mine. 108 LSA and solid lifters.

Found a better picture:

Will it fit under the A12 scoop with an air cleaner? Back in the 80's I used to help someone at the track that had a '70 Cuda with this intake. Air cleaner did not fit so he did not run one. Obviously not an A12 hood, but I do not remember which hood it was using. Still a valid question, this intake is much taller than the stock 6-bbl intake. Paul Rossi ran it in his '70 Challenger with a T/A hood, he is the one who was responsible for getting Weiand and Mopar to make and sell this intake. I have not seen any engine pictures of his car, so do not know if he ran an air cleaner or not.

I have a tunnel ram on my 71 dart,400 engine,2-4500 on indy tunnel ram,fits under my 6-pack hood

It would be problematic

The MP M-1 tunnel ram is short, well relatively. They are NS-1 so you'll need to check the usual places to find one.

OhioGTX has an M1 tunnel ram in his 9 second GTX, it fits under a 6pak scoop but I do not know if he runs an air cleaner or not.

Update: I went with an Edelbrock Performer RPM intake and Holley 850 Ultra XP carb. It also has a NOS plate and a 1" phenolic spacer. All of this with a large oval K&N 3" air filter that with filter base and lid is 3.5". This all clears the 6 pac scoop hood with no issues at all.
