Kowboy, I found info on this casting number today and remembered you asking..

3994257 67 - '72 250 cu in.

Ok all youze 6 cyl.- guys - whats the largest 6 cyl chev engine (gas type) That is made and could be installed in an early?? I know ford made a 300=?/

292.
and an avaliable crane camshaft, cylinder head work, with a four barrell intake and headers nets you about 300 hp.

COOL!! Theos blocks are everywhere around here.Thanx

Matt,
Keep in mind that The Chevy 292 was an inline, six-cylinder engine with a bore and stroke of 3.875 inches by 4.125 inches and a compression ratio of 8.0-to-1. It achieved a maximum 165 gross-horsepower at 3,800 rpm and netted 147 horsepower at 3,600 rpm. It reached its maximum gross torque of 280 pound-feet at 1,600 rpm and netted 262 pound-feet of torque at 2,000 rpm.

Basically it's a tractor motor. It will get fairly poor gas milage no matter what you do but if your looking at towing, it has enough torque to climb a tree! The 250 is a very good mix of both. You can get 18mpg if configured correctly and still tow with ease.
