Trick Flow small block heads

PRH said
Imo, that's the make or break number.

If they won’t make an honest 600hp(ootb) on a “suitable” bracket race type short block, then they’re not as good as they really should be.

I think they’d do it though.

I’ve made 589hp from RPM’s that weren’t anything too special.

We did a “hot street” 410 a few years ago.
10.5cr, tweaked RPM’s, Victor, qft 850, small/slow solid roller 251/259-108, .600/.600.
I wasn’t the one who tested it, and it sure looks like there was power left on the table with the tune up...... but it made 524tq/538hp as it was.
The a/f ratio was still way rich(11’s) and I feel like there was probably another 10-15hp in it with the carb sorted out better.

I agree totally.

I just don't get the panic over this. First, the dyno numbers were called into question. Grey is not some poser.

Then the head is declared substandard because the dyno numbers didn't pan out the way the forum thought they should.

I've seen the heads. Had my hands on them. For an OOTB head they are about the best I've seen.

If they were mine, I'd do a 50 degree seat on them and go. I wouldn't even fluff the short turns, unless I got them on the bench and didn't like what I saw.

They should do 600 with a well thought out combo. Like I said, after 600 HP it gets to be a ***** to get more power out of that architecture.
