New Trick Flow FE cylinder heads & Intake

[chilly460]

Nice little combo, Brent.  Quick swag there would be 525hp, 500lbft with peaks around 6300/4800 respectively.  I like all these ~390 builds to compare to the 383 Chevy guys

Hey Brent, I just milled .250 off the stands on a T&D single shaft set-up, and it came out right-on.  Sounds like an RPM intake is a better fit for that combo.  I think I like the TFS intake so far......will dyno one on a 428 in a few weeks.  It seems to need less work than a Victor to get to a similar place........if a single plane is the right avenue.

Wow a quarter inch off the stands to get ‘em right?

[CaptCobrajet]

Yessir.  The pedestals on the TFS head are .300 taller, and the valves are longer.  Milling .250 off the rocker stands made it have really nice geometry.

Since the valves are longer, it sounds like the whole internal architecture is raised. Is that right? What's the purpose of that, to raise the port roof? I assume the valve seats are raised also? I don't get why TFS changed all this stuff, unless it was all for raising the roof of the port. Longer valves seem like somewhat of a drawback since there's added weight to the valvetrain.

BP, have you ever cut down a set of factory stands that much?  Or do you think it'd be easier to start with HR stands and shim up?

[CaptCobrajet]

I think I would just get good billet aluminum stands and machine them.  It would take a lot of shim under a High Riser stand, and they aren't cheap.  The "base" of the standard OE stand isn't thick enough to mill .250 and still retain a good platform.   We just put the shaft through the billet stands, and turn them upside down in the Kurt vise, and mill them all exactly the same.

Yeah, I went ahead and got a set of stands ordered yesterday.

Sneaking up on it. 

I'm at .175".  Pattern is getting much better, but still some left in it.

This months Hemmings muscle machines has a Trick Flo ad that says with its Power port 175 heads and a 482 CI FE Car Craft  made over 700hp its just inside the front cover.

Thought this was best posted on this thread.

I don't want to start a new argument about dyno results on this thread, rather my intended purpose is to further healthy conversation about the TF heads.

Now that Brent has built and tested a nice little 395 with these heads that seems punch well above its weight, I am that much more confident that had this 700 HP 482 been tested elsewhere it would have put up similarly impressive results.

While it's probably not really a good idea to compare a ~530HP 395 to a ~700HP 482, it does add a bit more data to judge the heads by.

thoughts?
