Looking for opinions on Mopar M1 single plane intake

[B3422w5]

Anybody used this intake? How does it compare with the victor junior?
I have one i am thinking of using on my 418 build with the new trick flow heads when they come out.
Thanks

I raced one years ago. It didn't have much bottom end but great top end. You sure knew when you hit the power band.

Figure on the convertor flashing somewhere 5200-5400, and shifting it at 6600-6800, hopefully it makes power in that range?

Oh yea, if I remember correctly it came on real strong about 4000 and just kept pulling.

If you want opinions...I had 4 of them, Had two on bracket cars....I have none of them and am using Victor 340 on everything...the back half numbers were better with the Victor then the MP1....besides they got that stupid Thermoflush carb pattern....my opinion....LOL

Yep, kinda figured that was the case. Might sell it and get a Victor

Fix the flange. It's relatively simple. Once you do that it will run with the Victor.

I'd run a Victor.

The M1 is old, designed for grass roots racers and super stock, copies from the Holley Strip Dominator and performed a little better. The TQ pad made it good for Super Stock racers and street guys that could reuse the TQ. The long sweeping runners are well designed and are narrow. Not generously huge. The work really well on a 340/360.

Since the rpm, and then the Victor, it isn’t as powerful. It is a good intake, but for racing.... chasing the points and money, Victor series for the most part or a Indy. Member UOP has track tested the rpm vs the m1 & found the rpm quicker. IIRC, he was running low 11’s.

Modification to the carb pad isn’t so EZ for many and probably cost prohibitive for some.

IMO, is save the single plane for race cars quicker than what UOP was running. It was a close match then.

I like the Torker 2 340, if you spin it 62-_300 plus RPM.. You need a 3200- 3500 converter ,and at least a 3"91 gear ....and a 27" tall tire ....and chassis mods

 

[rumblefish360]

I think I would have liked that intake (TorkerII 340) a little more if the runners were longer and the plenum reduced a bit.

Agreement.
However, I like more converter, and deeper gear than most, Rob

I am, what I’d consider, a 4sd (manual trans) guy. So it’s not more converter but for certainly more gear and cam than what an auto trans would use.

Is there somewhere I can research fixing the flange? I just switched to an M1 on my magnum motor since I'm adding a Procharger and it's the only option for magnum single plane. Didn't know about the thermoquad flange until I got it in the mail

Search posts by IQ52. Though he is retired, perhaps his son is OK to do the work. If not, copy the pictures for a local machinist to copy.

Indy makes a single plane intake for the magnum 360.

 

[rumblefish360]

And that’s one bitchin intake.

That’s the intake I bought for my magnum 360. I bought it for $300 shipped brand new.

 

[B3422w5]

They dont make that for non magnum do they?..... standard type head

 

[rumblefish360]

The Indy? I’m sure the do!
Scroll down a bit to the LA section, get the part number and call them.

Saw that. Wasnt sure if that was for the rectangle and oval port Indy heads or not.... the -1 and -2 heads, or standard production head
