Amazing as always! I'm always impressed with how well you can package everything tight to the engine.

Cool pic, Tom!

Back in the day, I was into ZR1's, they were pretty cool cars. I had 4 Lingenfelter modded cars. A stock displacement head/cams '91, 385 stroker, a 415ci n/a and one of 4 TT ZR1s that John built when he was alive.. The TT car made 760rwh on 14psi with small turbos and would pull all the way to 7500 rpm. My 415 car was the fastest N/A ZR1 in the day..10.47@135. The ZR1's would rev like crazy but were not good for track days, they overheated too easily..
