ahh i thought it was 10's but i wasn't sure. the engine is probably a stroked 250 or a destroked 292. i've heard that if you can find a 292 from a farm equipment(not sure if it's tractor or truck etc) the crankshafts are perfectly balanced. my friend was telling me that he used to race them and had a old one that he kicked on the ground once and it rolled away. his race 292 put out soo much torque he had to drill and tap/stud inbetween the flywheel bolts because he would shear them.
