There are posts on Facebook and For A bodies Only saying they are available. But Summit racing say they are shipping them in March. I just wanted to pass along the info.

A-tech is showing they are ready to ship today.

3 versions (of 4) are available since last week from Summit.

Summit TFS-6161

TFS-61617801-C01 1.460" dual valve springs, 270cc intake runners
TFS-61617802-C01 1.550" dual valve springs, 270cc intake runners
TFS-6161T783-C01 1.550" dual valve springs and titanium retainers,270cc intake runners
TFS-6161T784-C01 1.560" dual valve springs and titanium retainers,270cc intake runners

1st run is shipped and 3-4 weeks on the next shipment is what I was told by trick flow but then again they also told me that the 270cc head was non max wedge port but turns out they are a max wedge port

Wait... all this waiting and they want 600 bucks more for a pair of heads that flow 17 CFM more? And flow no different up to .400 lift with a 30 cc bigger port? With the same exhaust port? Really?

I noticed the description says raised runners; the pics on Summit do show an intake port configuration like an Indy EZ where it's raised and extended enough to use a valley cover, instead of an OEM-style pan.

The CNC finish is TF's Competition style, not the Street style used with the 240s.

For all the changes, I would have expected higher flow rates. However, TF chose to stay with standard-offset intake rockers, so there is only so much port area available to work with when you have that constraint built into the design.

Until someone fixes the crappy valve position which opens right into the cylinder wall they can throw all the port size they want at it. Somebody really needs to do a better head and so what if it requires different valve notches in your pistons--look at the success of the Kaase P51. J.Rob

Correct RAMM 👍👍👍👍👍

$600 more??

I see $380 and $400 more, per pair, depending on which spring package you get.

Still an incredible bargain IMO.

Dwayne are those flow #s legit? Seems high for .600 lift?

Not positive but I think it was Larry Smith in North Carolina posted some pictures of the 270 heads on Facebook yesterday and is going to do some testing and see what they are capable of after some port work.

TF's advertised intake #s for their MW 270 are very close across the entire lift curve to the standard-port Victors that Dwayne did for me last year. I don't see anything out of line with TF's claims.

I hear ya'...

harland sharp only???

That is just what Trick Flow recommends. Obviously lots of other rocker arms fit (or can be made to fit).

The numbers don't seem out of line, but they're just "numbers" to me until I get the chance to put one on the bench.

The advertised numbers for the 240's and the numbers I got weren't that far apart, and I'd expect the same from the 270's.

Saw that too.

Larry Smith opened my 240s up to 249CCs, they flow 370 @700 lift.
It will be interesting to see where the 270s end up, with the design limitations.

Larry is working on a set of the 270cc heads going to be interesting to see how much more is left in these heads

They appear to be better than the MW SR's you did for me?
TF has same size int valve, but smaller ex valve.
What volume do the MW SRs have?
Thanks, Don
