Extensively modified TF 235 results
Chris Frank gave me a hand getting this thing going. I called him over a year ago quizzing him about a cylinder head thread I had read here on LS1 Tech. He started with a set of rough CNC TF 235's, used his port design, welded the chambers as I had -10cc pistons.

235/243 .647/.654
Fast 102 re port by Chris Frank
NW 102 TB
AR 1 7/8's 3" mid section cat's
SW 3" Cat Back
6 spd 4:10's
RPS Carbon Street Lite
The chassis dyno is a Mustang, accurately calibrated. Parasitic Multiplier is set to 2.1 rather than 1.0, it will display similar numbers you would expect from Dyno Jet this way.
I had street tuned the car & knew it was day & night over the previous combination, 550/500 was my target & I believed we should be in that range. It was very nice to pleasantly suprised with these results.
The very first dyno run was 595/506 which also was the lowest, I wanted to pack everything & go home at that point

Very nice results! I have a very similar combo, 416 with tea tfs 245 with a bit larger cam (243 251). Also running a vac pump. Everything else is the same though, gear, tranny , ,exhaust and intake( ported my me).
You definitely exceeded your goals by far, very nice attention to detail. What's the compression and what vehicle is this in?

These heads come from trick flow as porters castings and the port design is our own in house design.

With just a cylinder head change and our ported fast manifold Dale picked up 75+hp to the tires with our combo over the competitors custom heads and manifold. Dale didn't change anything else on the engine. Frankenstein has always let the numbers speak for themselves. Great job on the build Dale and I hope it makes you happy after the two years of struggle with the old combo.

Ron here, dales tuna student.
I could see Dale's smile all the way from Canada and I'm in Oregon.
I was supposed to be there for the dyno weekend.
I guarantee that his C5 is all but out of control with that much HP. Just the way we like it!
For example, my 69 Nova is in that area and has been in the high nines and weighs a bit more. That's some serious power and at a very nice 6500 rpm.
Nice work guys

With my AFR's I'm almost at the point of diminishing returns. The money can be more appropriately allocated towards his TFS casting; coupled with larger lighter valves, custom chamber work, hand finishing...
It's just nice that a guy that works with some of the biggest names in racing picked up the phone and had a conversation with little ole me, if that makes sense.
