Dyno #'s with Trickflow Heads

Eh....was this satire?? Its hard to read tone over the internet...but those 2 power curves show a MASSIVE increase in power.

That is my point. If you can't read the scale of the graph, that might be 5 hp or 50. But the torque is nearly identical, it's 'just a little higher and about the same curve'.

the op states there was only 3 hp increase and 6 ft of torque over the whole rpm range so that would be nearly identical to me .

So I finally got my trickflow 190 powerport heads installed & got the car on the dyno. My previous heads were a set of EQ magnum heads that were done up by IMM. Very disappointing results, car only gained 2 rwhp and 6 rwtq. Guess the EQ heads were the real deal, should have left well enough alone. Car made 292 rwhp and 311 rwtq @ 5500rpm 36 degree total timing & AFR 12.85.

Says nothing about the curve....until:

No never got flow numbers from Brian on the heads. The car ran great, definitely regretting my 2400 head investment. Just figured the trickflow would be a better head. I guess the cam might be hurting performance but I figured I would have at least picked up 15 or 20rwhp with the trickflows. Looking at the dyno graphs from both setups, the power curve & pulls look almost identical.

Which is precisely why I asked if he could post 'em. Y'all are guessing until he does so because he's using marginal wording like 'almost identical' and citing peak value figures exclusively which typically (no offense to OP) are things that people unfamiliar with dyno charts interpret them.

I remember people stabbing cams into their Twin Cam 88 Harley's and really 'feeling it come on the cam' at 4800, with a redline coming up quick. Uh, no. That cam made less peak power and torque, and they're just feeling it come out of the huge hole in the torque curve because the tuning sucks, which feels like a powerband at that point.

So, OP, post 'em up. With fuel curves if you got 'em.
