Cool Any experience with LE 21* Trickflows?

Just checking in to see if anyone has had a chance to dyno with these heads or run them at the track?

They will be topping my new build, as I have already purchased them and sent my intake to Lloyd. (Excellent customer service by the way. I even told him I had my heart set on AI for several years when I first started talking to him. His willingness to take the time to talk with me over the phone and by email along with his great reputation swayed me in his direction and I'm sure I won't regret it.)

If anyone could post some results I would appreciate it. I'm pretty excited to get my engine together as soon as they arrive.
My build looks like this.

353.3ci
Forged Eagle crank
Forged Scat rods
Forged -5cc CP Pistons, rings gapped for nitrous
LS1 lid conversion
58mm TB
40# injectors
LTCC Coil Conversion
LS2 Coils
LE Fully Ported Intake
LE 21* Trickflow Heads 2.055in, 1.60ex valves 215cc Intake runners
LE Cam 237/245 .603/.611 110LSA
LS7 Lifters
1.6 Ultra Pro Mags
1.75" Longtubes
3600-4000 Performabuilt 10.5" billet stall (shipping it back for a restall, currently undecided on how big I want to go)
Performabuilt Level 2 4L60e
3.73 gears
10 bolt for a little while until i can afford a 12 bolt
A/C Delete and EWP
Drag Radials (currently a good set of 555R's, going to MT's after the nittos are used up)
BMR Lower control arms
150-200 shot of nitrous from NOS wet kit and progressive controller.

Sounds like it should move. You're current setup will probably be traction limited. Some good suspension parts and you'll definitely be moving.

I'll be somewhat limited until I get this 10-bolt out. The car squats pretty well. If I can pull some 1.5x 60' times on the 10-bolt I'll be happy. I won't be spraying out of the hole until I get a 12-bolt.

I'll have to look him up. I really think these heads with Lloyds work applied could be as capable as any heads out there right now for the LT1.

I was originally going with the AI version of these heads decided to go the LE route on my entire top end. I'm keeping it as close to a Daily Driver as I possibly can and we usually see 2500-3000 DA around here so if I can have a Daily Driver run 9's on pump gas in 3000 DA I'll be thrilled.

Went from LE2's and LE HR cam ran 11.35 @ 122 to AI 212 TFS and AI HR cam ran 11.10 @ 124. It lost bottom end but gained power up top. Everything else in the car stayed the same, other than the tune. LE setup done on dyno by Ed Wright, AI setup done on a dyno Moehorsepower. Different weather and dyno's so numbers really arent compairable but total HP and TQ was within 25 between setups.

Sounds about right going from ported stockers to ported aftermarket castings .

Last I heard he had bought an LS autocross car, I'd imagine he sold the LT to fund that project.

That was pretty much exactly it. His lt1 with le trick flows flat moved though. I was sad to see the car go. The new owner got a sweet ride.
