Hi All,

A true 426ci engine is a 4.252 bore.

If you go 0.062 over, it will be a 438ci engine...

Doesn't quite have the same ring to it?

Carpe diem, quam minimum credula postero, thanx Horace!

There’s no point trying to fix stuff that ain’t broke,,, 'but if ain’t broke',,, you is not trying hard enough...
