That is the M1 intake for the B motor with a 4500 flange on it. It seems like the perfect intake for a 500 inch low deck motor running Edelbrock or MP heads. Modern has a CNC program for the Eddy heads that really makes them work and the 4500 carb should be a good match for any 500 inch motor.

I'm pretty sure it is the only low deck intake with a 4500 flange that fits standard ports. Weiand makes a RB intake with the 4500 flange and now Edelbrock is going to make a RB version of the Super Victor, but nobody else makes a B version.

Just seems like it would be a popular intake for anyone racing a big low deck motor with standard ports. I assumed it was a popular intake until I tried to buy one! Basically impossible to find because the sales volume is so low on it.

I ran that intake when I went 10.09 and havn`t been able to get the et. back w/the victor however, I was also sucking oil and my tires were SHOT. I saw your manfold shoot-out and the standard victor out did all of the standard port manifolds if I remember correctly. Have you done any back-to-back dyno tests yet comparing the standard port manifolds and if so, which were the best? THANKXX ANDY.......

Well when I did the manifold flow test article I didn't have a 724 on hand. I'm sure the flow on it is going to be down a little bit when compared to a MW port intake like the Indy 400-2, but that is to be expected with the smaller runner size.

You're right, the Victor 383 is probably the best standard port race intake for the low deck with a 4150 flange. But what about the guy with a 500 inch motor that wants to run a Dominator?

I could do a dyno test between the Victor 383 with a 4500 adapter and a M1 724. That might be an interesting test. The problem with the Victor 383 + adapter is that it is going to be a very tall setup. The M1 724 could run a spacer and still not be as tall as the Victor with an adapter.

Has the BB Victor really showed its nails in any combination yet? I don't know anything about intakes either, the victor looks impressive, but in my opinion has got a very small plenum. Maybe they have compromised the height a little ro something, I don't know. But from what I have followed, ti hasn't really been the "best" intake for any combination so far. Not bad, but not way beyond way less impressive looking intakes either.

I think I screwed up when I bought the victor hype and then sold the m-1 w/out first testing the victor. Based on my last outing with the oil sucking issues,30-40 mph winds and wore out tires I still managed a 10.23 @ 131.28 mph and a lot of racers said they were way off on their et`s also. If this intake doesn`t work, I`m gettin a tunnel-ram w/a couple of 750`s and we`ll go from there.

The plenum on the 724 intake is huge compared to the Victor 383 intake. Who knows, if a guy wants to run a 4150 carb maybe the 724 with a 4500 to 4150 adapter is the way to go???

I could probably try that on the dyno. It might be interesting to see what happens. I'd have to get me a 4500 to 4150 adapter since usually the adapters are the other way.

I think the Victor 383 is an okay intake but for a 500 inch motor I'd rather run a 4500 carb. Assuming other people think the same way, the 724 intake should be more popular than it is.

I run that intake on my 470" b engine. I basically built my engine from the back of the Chuck Senatore book. I chose it because I could run the 4500 carb and still close my hood. bought mine on ebay for $200.00 new. I am happy with the outcome, brand new baby and fixing my CTD ram has put a slowdown on getting it to the track so far but I should make it this summer.

That is exactly what I was thinking: Having a 500 inch motor with a 4500 carb and being able to close the hood!

I am by no means an expert on anything. Yes I copied my engine out of the back of a book. The section on manifolds said that The M1 tested out the best in that application, I got alot of advice on the carb and went with a 1050 (8082) I am happy with the results, could use a touch more gear but the 4spd helps alot. I am gonna get some track time in this summer I just have alot going on right now and it's not a priority. An with what I spent fixing my Truck the last few months I could have bought a trailer and a years supply of tires and fuel. I do take the car out for a drive in the country once in a while. and it all fits under my stock charger hood.

Andy, Weiand makes, or made, a B motor Team G intake with 4500 flange. A pal of mine has run one since 1990.

fits fine

The weiand intake is alot taller than the M1
summit list it

Summit does list the 724 for sale ($270) but it isn't in inventory and if you order one it might not show up. Mancini Racing lists the same intake for only $220 (a steal of a price) but once again, it isn't in stock and MP shows no inventory on hand.

There is a dealer somewhere back East that has one in stock. Ken's Dodge or something like that. I didn't bother calling them to see if they actually had it or not.

I did order one from Mancini Racing. We'll see how long it takes to show up. I heard thru the grapevine that MP does actually have these things in inventory but they aren't in the system. So hopefully my order will get filled.

BTW - that motor looks great. And thanks for buying the throttle bracket and throttle return kit! I didn't notice them at first since you had painted them engine color.

Your welcome. got them from Mancini
I guess I lucked out. I was on ebay one afternoon and picked up my M1
My engine was painted on the stand. including the brackets. keeps the leaks down.
used one of the pioneer cables from autozone that I ordered with a part number from the tech archives, I had to try a few but it all works and I think it is a clean look. I couldnt get the lokar cable to work well, then I did and the cable snapped. Just my opinion but for $20.00 the replacement cable is ten times better than the lokar. Just need to get a better camera cause that is hemi orange but doesnt photo to well.

I would like to see the difference between the M1 4500 intake verses the new super victor 4500 flange intake. I'm not sure on the height of the super victor but it is suppose to be a new design over the victor. Hey Josh68, let me know when you make it to the track. I would love to see your car ripping it up. LATER

Andy,

Can you tell us more about the test motor? Given the cubes and HP, it sounds like an all out race motor, with not much concern on the bottom end?

Thx
