Has anyone stroked their Vortec lately?

I have to get it on a dyno, but have to find one in Germany. I will dig out my receipts and see what it cost.

sorry i didnt add in that also a decent cam is also required..

there are multiple articles out there for this same exact setup ( Lq4 upgraded with L92 heads, manifold, cam)

the price ranges vary depending on what you replace.. but there are builds for 550 rwhp for about $4.5k
