I can't find it in a high temp paint.

I am blasting them and trying again. But I will do some samples on a peice of steel first this time.

Retails for $1,300 so it would want to look good too. Thankfully I won't pay quite that much for it.

Ok so she's basically ready for Finke this year. Nomination is in.

Just need some final testing for suspension, jetting, gearing and some race numbers.

I'm trying to find about any jetting and suspension spec's they used on them back in the day if anyone knows.

I hear a guy called Eddie Baldissera set them up for Gall and Curtis back in the day. Any idea of how to contact him? I think they used a completely different carby.

there is a trick to extend the pilot jet deeper into the bowl with some hose to prevent the vibrations allowing air into the pilot circuit. this stops the pinging apparently

Interesting.  Ill have to look into that. The vibration at constant high speeds is a problem. My hands go numb.
