Andy, what were the results of the 470/270 combo with the 440-3 ported? I just read it was 50hp down in power before porting.

Wasn't it about 1200 HP?

Oh, sorry... must be still thinking about the 2020 Drag Pak thread... laugh2


An unskilled person with a "cool idea", a bunch of porting tools, and a set of cylinder heads is a sure recipe for disaster.
I AM that person!

My mistake. Yes 400-3. Just curious as I use the 400-3 as well and I originally suspected the heads, cam or intake for my low power woes. I no longer suspect the cam, but compression or intake as of now for the lost ponys.

The 440-3 didn't work very well out of the box. Once it was ported the engine made pretty good power. There wasn't a 50 hp difference between ported and unported, more like 15 hp at peak. But it is about more than peak power, the unported intake had a roller coaster power curve while the ported one was nice and smooth. The EGTs smoothed out with the ported intake and the engine sounded better.

I don't even bother building serious engines anymore with a cast intake. At the minimum I'll send them to Hughes for their deep port match. If the budget allows then I send the intake to Wilson or I have a local guy do it if he has time. None of the existing Mopar intakes fit very well out of the box. Indy castings tend to be way off and so are Edelbrock. Trick Flow used to be good but the last few I've looked at were way off also.

I see. Looks like best would be to just purchase intake from Hughes with it deep ported? If my cam is installed correctly and the heads dont improve much a different intake will be in the works. TF most likely.

Trick flow std port intake on your MW sized heads?? work

I actually think Andy did try the TF manifold on the 270 heads.
I don’t remember that combo being too special....... but there were a lot of tests, and I may be remembering it wrong.

Yeah, I thought they could deep port match it to max wedge? My mw ports are not much bigger than the TF270 int port. There was a mopar engine builder near me MRL, used to hange out on A and B bodies. He built a guy a 470 with cast 440-1 heads, used a nonport matched standard port intake. Made over 700hp. Didn't seem to hurt it. Have you performed any studies on what's gained or lost on port matching vs not? Curious

I don’t recall doing any testing between ootb vs port matched intake manifolds......... but.......

I did have a 557 on the dyno making about 835hp with an ootb 440-3.

I’m sure if you read thru Andy’s tests of the 270 heads, you’ll find where he tried the std port intake.

I'll have to look again, didn't see that. I would think as long as the clylinderhead intake port is larger than the intake port, it wouldn't be very detrimental. Other way around would be a big problem.

A Wilson ported M1 with standard ports worked better with my 270 heads than an OOTB Indy 400-2 intake. Once the 400-2 was ported then it worked better. The Indy 400-2 out of the box was a pig. Once it was reworked by Wilson it ran pretty well. Your results may vary. I was working with a fairly well sorted out combo. That was a pump gas 470 that was making over 750 hp. I think the best set of pulls was 780 hp. Most guys don't spend the time and money to dial in a combination like that. If you knock 100 hp off the engine then the OOTB intake probably works just fine.

Why not get the ultimate Dave and go T-Ram which I plan on in the near future.....better power and distribution than any single set up.......Up the compression, get a .700ish lift solid roller and hang on............

C’mon Dave...... you’ve said “whatever it takes”....... just box that thing of yours up and send it off for porting.

First things first guys. Heads are headed to Detroit next friday. Still checking all my options with these heads. Angle milling is not off the table just yet. I need to get an opinion and price from Sanchez first.
Dom, the T ram combo is still a couple yrs out, but still high on my list. The combo I'm looking at is $2500+ .

I was very happy with my Indy 4500 after I got it back from Wilson
With a smaller ported head the car ran basically the same as it did with a more ported EZ and unported manifold.
So what ever they did helped for sure. Expensive though.
