'Exotic' Camaros?

[BillOhio]

I cant remember enough of the story but I think it was in a z28 at the time.

Yes I had a yellow RS Z with one of those hemi headed i engines put in it by Dave Tinnell for Carl Dwiggins. Neat looking but they didn’t make any power.  There will be one of the Turbine cars at MCACN.

Was the aluminum 302 in your '67 Z/28-RS a Chevy engineering engine?

[Charley]

It started out as a bare unfinished block that came from GM engineering. The only machining done was the pan rails. All other machining had to get referenced from the rails. Took years to get it all machined as there weren't alot of places that could do that stuff back then.

Ford was working on a Tunnel Port 302 for Trans Am racing
so Chevy came up with the 'Semi-Hemi' heads for their 302
but they didn't make more power then the ported stock heads

don't forget the ZL-1 Camaro was pretty exotic

it was a hand built $3000 engine option

Did you sleeve the block, Charley?

I didn't build it. A friend built it. As I recall it was about a 20 year project. I don't think even the lifter bores had been drilled.
