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.
 
Do you have enough cam to take advantage of the flow the TF's are capable of flowing?
 
Currently running Ld340 intake, lunati voodoo cam with 1.6 rockers.

Camshaft, Hydraulic Flat Tappet, Advertised Duration 268/276, Lift .494/.513, Mopar, Small Block,

With that cam in the above post You’re obviously not taking advantage of the TF’s, but that’s an easy fix. Did IMM provide flow numbers of those EQ’s? Ported I assume? Are the TrickFlows ootb or additionally massaged?

Not sure if that's enough cam to take advantage of the difference.
 
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.
 
Sell the EQ’s and valve gear to offset the cost of the TF’s. Monday morning armchair question: why not up the cam while that major surgery was being performed?
 
Did you do a BEFORE and AFTER on the SAME dyno with the SAME operator?
 
Yes, same dyno & operator. I did sell the EQs to offset the cost. Couldn't swing the new cam, harland sharp rockers & the head. Tax time is here so time for a cam upgrade. Anyone have a recommendation?

What's your displacement? Measured compression? Have you done any oil mods for more rpms? Planning to stick with a HFT cam?

I'm not sure I would spend any more until I was SURE I had maximized the combo with the new heads. I think something's amiss, as badass as the Trick Flows are supposed to be.

Either that or IMM REALLY knew what he was doing.......which wouldn't surprise me.
 
71 340 bored.30 over. Just a basic rebuild not a high performance build. No oiling mods & unfortunately never measured compression. Did do a compression check on each cylinder with new heads. Numbers were consistent cylinder to cylinder around 165psi give or take 5psi. Though that seemed a little low with the smaller cc chamber than what was on the EQs
 
I think your looking at it all wrong.
You obviously had a well ported head, yet the stock TF out performed.
Now put a much bigger cam, and raise you shift point. let them TF Breath.

Keep in mind the TrickFlow Head is a nicely cnc ported head. Not your typical out of the box heads that we are used to. He need a bigger cam. Hopefully at least a solid lifter cam from Racer Brown or someone that can take advantage of the head flow.
 
U need at least .550 lift to even think about tapping the power potential of the Trick Flows. And even at that lift they will be screaming for more. Kim
 
I run Brians EQs on my Barracuda and they flow around 270 @ .550.
So you wont notice much difference unless you run more cam etc.

It's all about the application.
Stockish 340...small'ish cid
Eq heads port sizing is a velocity winner.
Turn the CID up or raise the compression to 11.1 and lift the valve .575...and the TF heads will really come alive.

You basically put the cart in front of the horse.
 
I bet a nice hyd roller with 550+ lift on 112 type of cam would make it scream and not lose any drivability.
Have Jones or someone design or recommend a good grind.
