Known ZL1?
Does anyone know this car? Saw it at a local restoration shop car show a couple weeks ago. I was just wondering if anyone knows the car. The block has had some extensive repairs. Couldn't get the VIN. It was covered by a"Don't Touch" sign.

That looks like a clone of the silver RS ZL1 that Craig Jackson owns. Same stripes.

Re: Known ZL1?
On my ZL-1 block, I had to do some lifterbore repairs like that as well. Seems that the shop said there was evidence of core-shift for this 052 casting, and with high lift cam and heavy springs, they said it wore over time on the side of the lifter bores. My repair also made it so my bore are bushed and set up for .903 Jesels. Alot stronger in the lifterbore are now.

Aluminum. Very repairable.

Re: Known ZL1?
I imagine they start with thin plate aluminum and then build beads on top of that until they get is contour close. They it is grind, check, grind, check, until it gets to the level the repairman wants. This one looks like it would benefit from a bit more grinding and checking. When it comes to original ZL1 blocks, beggers can't be choosers and most everything is repairable. Cool looking car and looks like an exciting build.

Re: Known ZL1?
I dont like that repair at all... I fixed a huge hole in an alum Grand Sport head and it looks way better..and I am a novice welder... I think the bodyman side of me made a difference...
