My guess is if lug-centric balancing was critical, no-one would have Rally IIs. It might be a technically better way to balance these but I speculate the odds of NEEDING lug-centric is low enough...

Your progress is impressive. Way to stick with it.

I'm curious how you manage the dust. Are you using blocks with vacuum extraction or just cleaning up a lot?

I wasn't going to pull the starter for this. I decided to be happily lazy instead.

I loosened the tube and wrassled the sleeve down about an inch and a half before I gave up.

That tidbit about a non-visible duct molded in color is an interesting contrast to a lot of modern cost-focused decisions. Lots of overhead in sourcing, inventory, manufacturing,...

Nice !!!

Interesting to see the lower AC duct painted the dash color (looks good!). For some reason I thought they were all black in 70... but yard work in this heat probably did some damage.

I don't remember this thread but I hope he bought the 18 heads.

As I understand, the 11 heads are more like 87 or 88cc and the CR on a 1970 350 might not even be 8.0:1.
