Yes, 1.7 is the rocker ratio, acts like a mild cam. An aluminum plate will do just fine if you're not looking to hot rod the truck. One member here has a Hughes plate and it's leaking again, but his manifold is suspected to be warped.

Yes, I have ran the M1 with just a few mods and it worked very well all round. The more mods you have the better it works of course but it will even help a almost stock motor perform better.

have you seen an increase in mileage? How about throttle response?

Who are you directing that at? lol Merc or me?

I have seen an increase in mileage and throttle response with the fixed kegger myself.

Mpg stayed the same or a little better, it was small amount not much. Throttle response is instant no bog or hesitation at all.

Will this intake fit my 2001? Is this the egr version? https://dodgeforum.com/forum/parts-s...dfw-texas.html

It'll fit. That's the EGR port in the second pic., the oblong hole and the round hole next to it. Just put a blockoff plate on it and your ready to go. It also has the two holes for temp sensors, one already has a plug in it. It's for the EGR engine, but it'll work fine on yours with the EGR port blocked off.

i have the airgap and its one of the best mods for the magnum along with sct and 1.7

@ lastrights, what did you end up doing with the IAT sensor?

p.s., I'm about 40 mins north of pittsburgh....near cranberry.

i have the m1 as well. but..... i also cammed my engine, as well as installed the hs 1.7's. im running a 50mm tb, and cannot believe the amount of low end tq i have.

truck also pulls extremely well all the way past 5k rpms. in fact when at full throttle, the engine wants to keep going, but shifts before redline.

i have yet to tow anything for more than a mile, but i cal already tell theres going to be a huge difference than before.

4.56 gears and 35's are next. tires before gears most likely...
