425 engine

Anonymous-0 · Nov 14, 2012

i have stumbled upon what is said to be a running 425 power unit for sale, for a reasonable price and i am thinking about buying it. and was wondering what heads it has and some of its pros and cons

It is just a 283 c.i. with two more cylinders. Probably the same or similar heads to what the UT, UB or 5 Star ran.

Thinking more about the 425, I don't know if it is original but the 425 in my G900-LP has two 4239s and a 4232 for heads. I need to get it steering before I worry about matching heads.

Id be interested in your 4239 if they ever become available
