I'm going to be forced to run an Indy intake on my 470 with the new 270 heads and I'm not really a fan of the Indy 4500 intake.
"Hello, Wilson Manifolds. I have another intake for you..." Yep, that is exactly what I ended up doing. Wilson did fantastic work as usual. I haven't gotten this engine back on the dyno yet but I'm sure it will pick up some power.

I wouldn't spend the money buying new heads if you already have the 240 heads. If haven't bought the heads yet then it might be worth going to the 270 heads even if you run the TF intake. Just be prepared to do some "hot rodding" to get them to work together. Maybe some welding and grinding on the intake for example. I made 750 hp with the 270 heads on a pump gas 470 shortblock with a standard port intake. But it was a very, very good standard port intake: http://www.hotrod.com/articles/dyno-day-trick-flow-270-mopar-heads/

IMO, TF really should have made the 240 head as a raised runner head....... If for no other reason than to get away from the std bathtub gasket.
I suppose there is an argument to keep them std port height to fit under low hoods, but I feel like the raised std port configuration would be a nice option.
I think if you made your own flat valley plate, and then used some "cut to fit" gaskets like what Hughes sells, and then raised the roof of the port opening as much as the TF or SV intake would facilitate....... You would bridge the performance gap between the 240 and 270 heads.

You would bridge the performance gap between the 240 and 270 heads. I agree. I think a raised standard port runner in the extended face 270 casting would be a great head for 470 or smaller engines. The raised runner would make more power than the standard location head but a person would be able to use a standard port intake.

Thanks AndyF, Any word if TF will ever offer a matching intake for the 270s? I have no idea what Trick Flow is thinking or planning. They don't tell me that kind of stuff. I told them that they need to do a MW intake and I told them that they need to add EFI bosses to their standard port intake but they haven't done either so I suspect that they don't care what I think.

The raised runner would make more power than the standard location head but a person would be able to use a standard port intake. At this point, it would just be a matter of them plugging in a std port CNC program into what is now the 270 head. It would be interesting to take a 270 head, and epoxy up one of the port openings and shrink it down to std size........ And see how much flow it actually loses. I bet it's not much at all.

Any before and after shots that show just how much work went into that intake? Looks like modern art now instead of an car part. Here is the view down the plenum. Wilson extended two of the runner dividers into the plenum and then fully ported and polished everything.

Wilson extended two of the runner dividers into the plenum and then fully ported and polished everything. I wonder why they didn't add extensions to all of the dividers, instead of only 2? I don't recall having seen it done that way before, since it's usually all of them getting the same modification.

Beats the heck out of me. I figure they know what they are doing, guess we'll see what the dyno says. I'm working on the new oil pump and lines and stuff like that so it might be a few weeks before I get this engine back on the dyno. In the meantime I've updated my website with the Trick Flow valley plates and batwings and stuff like that. (which is what this thread title says) Here is the link: http://arengineering.com/home-page/valley-plates/
