Whoops! I was just teasing Allen...honest! :-)
Actually, in the case of the TR6 <Shane's Triumph> they do get about
140hp with the home market fuel injection right? So those with
federal cars should be able extract more safely. But I think Shane
was actually talking about a cross-flow or "hemi" head right?
That could make some *power*.

My Spit is factory rated at 57hp. <no comments Richard!> The UK
version was 71 if I remember. I suppose I could modify it for
something over 100 but I dunno...I've heard sad stories. :-(
Perhaps my second car....then I'll have a backup!
