You should test the 270 heads with the same Wilson Modded M1 intake to see what it does even with the port mismatch. Since the intake Trick Flow recommends for these heads has a std. port window. I would be interested in the results of that test.
The only Carbs I care about are under the hood!

Especially since TF says that's what they used for their evaluation of the 270 heads.

Or a kind soul could let you borrow a nicely ported 400-3 intake..... Sure...... As the third one in the sequence.

Especially since TF says that's what they used for their evaluation of the 270 heads. Regardless of what TF says, I do not think the Wilson intake will work with the 270 heads. It bolts on there okay but there is so little material around the ports that I don't think the gasket can properly seal. I looked at it and decided not to run it since I didn't want to suck in the gasket during a pull.

Depending on how things go I might do another round of testing down the road after I send this 400-3 off for porting. Might be nice to have another ported 400-3 on hand at that point to do a comparison.

Does the TF intake cover the ports of the 270 heads better than the m1? If so, you could test that one on both sets of heads.

Everyone has their own priorities when testing, but to my way of thinking....... To not do a back to back test where the only thing changed is the heads, really just muddies the waters about how the heads themselves compare.
Test the 240 heads with the TF intake and the 4150 carb of your choice..... Get a number. Put the intake and carb back on the 270 heads as the starting point..... Get a number. That's a back to back comparison without anything else skewing the results.

Why not just test the 240 heads w/ a comparable out of the box manifold like you're gonna do w/ the 270 heads? Most people will not spend the big bucks like you did to have Wilson work their magic on an intake, so IMO you're giving the 240 heads an unfair advantage that will close the gap b/t the 2 heads.

Out of the box intakes stink, I've already proven that to myself multiple times with the 240 heads. The Victor 383 sucked, the Mopar M1 sucked, The Trick Flow intake didn't completely suck but it wasn't very good until Hughes did the deep port match. The Wilson modified M1 is the best low deck intake I have so that is my starting point. I expect the Indy intake to be fairly poor but we'll find out shortly.
