Mr. Black

Was an original 1997 C5 Corvette. 29k miles.

If someone happens to be looking for a similar goal or parts here is what I decided on doing.

Stripped off the top end. Goal was to have fun and keep a reasonable usable increase of power. Lots of broad torque. Well as much as you can with a 5.7.

BTR State 2 N/A cam.
LS6 Intake manifold.
Texas speed CNC ported 243 heads. 2.02 intake valves.
Texas Speed long tubes.
Texas Speed Hardened pushrods.
LS2 timing chain.
LS7 lifters.
Melling 295 oil pump.
RDE Fab timing chain dampener.
Hinson Motorsports plug wires.

Made 416/390 wheel on a Mustang Dyno.

In the end for having some choke points I'm pretty damn happy with that.

Here is a sub substandard video of the tuning and me rambling. and no I'm not a monetized youtube channel. I just do it for the hell of it.

Skip ahead 7 minutes if you don't want to listen to my nonsensical nonsense lol.

Looks like a good strong common-sense combo that will drive very nicely and still have a good fun element!

Nice build. I have the same cam waiting to go in an Ls2 for my Camaro.

Hope my results are as good.

I'm just over the border in BC and love to cruise NW Washington.

Mr. Black

Here you go z-camaro,

Mr. Black

Ha! the forum corrects your username as z-camaro. If I go in to edit it, it shows as correct.

I have the TSP 243 stage 1 heads and BTR stage 2 cam, TSP 1 3/4 headers and catted Y on my M6 TA and put down 400. Mine peaked at 6400 rpm as well. The dyno was acting up the day mine was strapped down and the Y pipe and single exhaust are probably costing me a few hp. I know by chart overlay that my car made 47 hp more than a TA with stock heads and BTR stage 3 cam, that produced 385 rwhp the day it was dynod.

Mr. Black

wannafbody your combo is one that I had been following before.

Have you driven it on the street yet? Mine feels better than stock from about 1500 rpm up.

Mr. Black

I have about 120 fantastic miles on her now. I love the way it drives. She rocks a bit at idle but I've had cammed LS engines before so I'm getting reused to that feel lol.

The only thing I notice is it takes ever so slightly more throttle input to get the car rolling but it really picks up over about 1500 rpms.

Mr. Black

My son and I took the Vette out today for a little rip today and beat on her pretty hard now that the new combo has some miles on it.

Needless to say I tried my first WOT 1-2 shift with the new combo and the clutch won't hold the power lmao. Didn't even bother trying the 2-3 shift.

Still totally driveable just no powershifting.

My LS6 clutch went out as well. I got a Diamond Stage 2 from Texas Drivetrain Performance waiting to go in.
