Awesome! The Merc looks like a Sabre Tooth rampaging through a herd of pu$$y cats.

Can you share motor spec's? Tranny?

Thanks, though some of those cats were fast.

The engine might be considered a scaled up Trans-Am motor that operates at lower rpm, as can be seen from the video: 555 c.i. with 4.25 stroke, aluminum block, C460 heads and manifold, steel rods, roller cam, Dominator-style carb, tri-y headers (2.25/3.00/4.00), two large Flowmaster mufflers upstream of two Coleman mufflers (required to make sound regs), cam driven MSD, 5-stage dry sump with a highly evolved oil pan and an AN20 return line, 2 oil coolers – air cooled and radiator cooled. Ambient temp was in triple digits when that video was taken.

Transmission is a dog box, now a Weismann (also like a Trans-Am car), which has an internal gear selection mechanism that allows for a better shift lever location to accommodate engine setback and offset. Clutch is multi-plate Tilton.

Thanks for the info!

Can you say the cam spec's and compression ratio? I'm not a racer. Just curious. Looks like about 7000 rpm max?

Great Car and race! Sorry she got tore up.

Damn, I still think that is the baddest car I have ever seen. Hope she isn't down for too long...
