Stop in for a cup of coffee

That's what worked well with my 68 Barracuda... the stock MP electronic light spring with one of the MP light advance springs...

But his engine may not like that as my cam was a larger.... But I thought that would be a good starting point...
What's his car got for ECU? Is it hooked up to a Chrsyler box or a HEI - that's one of the things TB does or offers with.
