Definitely would ditch the turbo; currently the flat slides are 39mm so those may or may not be too small.

A traditional distributor would be a plus for me even though it's a bit backwards. I've been eyeballing parts and everything seems pretty reasonable.

Additionally the ratios in the six speed box are very good; I even calculated max rpm in 6th with the short tires I use and the 4.38 final drive. Comes out to 128mph at 7500 rpm.
