Trickflow's 255 Heads
 

Anyone has any dyno or performance numbers on TFS's 255's?

I've been waiting on some also.

Are they cathedral or square port?

They're rectangle port, LS3/L92 style. Look to be a good head, I can't wait to see what TEA does with them.

That's what I thought. Do you think Trick Flow will do a cathedral port head bigger than 245cc? Do you think there would be a market for it?

I don't think so, if you need something that big you're better off with a rectangle head. I believe Mast makes a 275cc Head, which is monstrous.

That's kind of what I was thinking too.

Trick Flow do a 265cc cathederal head

^^ And it costs right at $4000!

I wasn't aware of that. I think at that point, I'd just go with LS3/LS7 style heads.

Just looking at the flow numbers the 255's put down on TFS's website, they have to produce some incredible hp/tq numbers on a stout bottom end with the right cam and intake! I'm really thinking about getting some for my 408, i think there just what I need!

The TFS 255's are Square port ls3 replacements and are smaller than stock ls3's so they aren't that big really , I know I'm looking forward to seeing results and as usual I bet they kick ass!
