The AC compressor lines might not clear the turbo with the Trick manifold so i might use the cheap up and forward facing headers and cast 90*​​​​​​​

 

8 bolt holes on the crank for the flywheel. Is that normal on newer engines, or do you need a special flywheel?

 

If you want to run a real exhaust, I'd use the trick kit.

I'd bet the Trick kit also holds more heat and has a higher velocity than those cheap headers, which should help you when driving on the street.

 

Flexplate/Flywheel

The crank shaft flange for the flex plate or flywheel on the LSX454 and LSX376-B15 is the same as the 2009 Production
Cadillac CTS-V super charged LSA engine. It uses a quantity of eight 10 mm fasteners.

 

I agree that the Trick kit is nicer but the cheep headers clear the Holley Mid Mount set-up. I'm still debating about switching to the truck style front drive or some 2010 Camaro exhaust manifolds and make a twin kit.

 

Any updates? I want to see this thing in action!
