402ci. LS results from Trick Flow Here is a basic combination we put together 2 years we would like to share. It’ a 10.63/1 402ci LS we put together for testing our 225cc LS heads on one of our in house Superflow engine dyno’s. The short block consisted of an Eagle crank, Eagle rods, Manley pistons and a Comp custom 244/244 @ .050 579/579 lift 111 LS installed @ 109 Cam. We tested a variety of manifolds but the graph represents an out of the box Fast 90. A nice combination using off the shelf parts that anyone could duplicate.

Very nice. I have a 402 with a set of your 215's. Love the performance I picked up over the afr 205's. +28.xx rwhp just from a head swap. Ron@Vengeance did a huge write up on the project. Link is in my sigs.
Awesome heads !!!

Nice power for 'out of the box' parts. With a little more pop in it that torque would come up a bit too.
I am doing one very close to this right now. Hard to beat these heads out of the box, area under the curve, up high at peak, really anywhere.

Thanks for the comments guys. We wanted to build a very easy combination that any of our customers can duplicate and expect the same results. We used all the parts out of the box-no hand work on the heads, no intake porting, and low compression compared to what we would have run if we were doing a max effort build.
Would more compression, a ported intake, and hand worked heads have helped? No doubt it would have made more power and torque. What we wanted to do was build a very attainable engine that anyone can build and show the results the “average guy” can achieve with out of the box parts.
GMHTP did a great installation article on our LS2 top end kit. A link is here:

Their test car with our top end kit ended up running deep in the 11’s at almost 120 MPH. Not bad for a stock shortblock in a full weight GTO

In my 402, Vengeance spec'd a 239/243 .623/.623 113+3 lsl lobed cam and it really nailed all my goals. Excellent peak numbers, and amazing power under the curve. 420 Rwtq@3000 rpms should back up that claim. 541 rwhp 505 rwtq !! And I had the 215's. Could I have expected a few more up top and similar low end with the TFS 225's ?
When its time to freshen this motor up I'd like to set it up for FI and run a set of unmilled tfs 235's. Thats going to be a future project though. Awesome line of heads !!!

Take the OP's post and add compression, proper cam and what do you get? Probably another 40+ flywheel hp and a significant increase in TQ as well.
Remember this is a setup that "ANYONE" can do, not just Tony Mamo. BTW don't you have nearly 3700 into your "special" afr 215s ?

Please re-read the post-a magazine did not cover the buildup. It was done at Trickflow on one of our two superflow 901's. We dyno test every product we sell, and also put every product through a 40 hour SAE durability test at varying load and throttle.
The magazine buildup was by GMHTP, on a stock LS2 shortblock. Very different stories but good data none the less.
Having two dynos in house allows us to supply customers good data on various combinations we test. For example, we have test data on our 205, 215, 225, 235 heads on various combinations ranging from a stock 5.3 to a well built 440 CID that makes nearly 700 Hp on pump gas.
If you have any other questions, please let us know.

and that comes at no small cost to your busniness. You guys certainly have an excellent LS head offering, and your contributions to forums are very valuable. Thank you Trickflow for helping elevate the performance industry. Thread Starter

Thanks for recognizing that. A lot of people don't realize how important, or expensive, owning our own dynos is or what having two full time, very talented dyno operators costs. To us, it is an essential part of doing business.
Thanks!

Ha ha what an A-hole comment. Read the OP's comments about low compression, small cam, with results that anyone could recreate in there own garage. Not a highly optimized, secretive (kept lift numbers on yours to yourself) build that has heads that are basically one off. Steve your afr 215's are so massaged I'm surprised Tony can even call them afr 215's. More like a completely reworked head to advertise the release of a new afr offering.
Take the OP's post and add compression, proper cam and what do you get? Probably another 40+ flywheel hp and a significant increase in TQ as well.

Steve,
They would be a few percent lower but in all honesty most flywheel (engine) dyno numbers are quoted with the STP correction factor.
Much like the norm is for the chassis dyno stuff to be quoted SAE, its just the opposite with flywheel numbers.
All the numbers I post from any of my flywheel dyno sessions (including the recent 215 AFR results) are using the same correction factor (STP).

Every post I see concerning Trick Flows makes it that much harder to hold off on buying mine.....I'm re-enlisting in April and a set of 215's will be my present to myself, along with a custom cam and FAST intake. I love seeing the results with these heads and can't wait to have a set on my engine. Very nice power, I'm anxious to see my outcome!

Nice work trickflow, made good #'s w/o being optimized.
