Time to do the engine swap in my 1978 Chevy Stepside as the L6 250 has really had it. What kind of power can I realistically expect from a doner L6 292 "street" replacement mill? I want to spend little $money$. Expect the usual stuff like a slight overbore, Mercruiser cam, headers, my redone 250 head, stock bottom end, a Eldebrock (or other?) intake, a small (how big?) 4 bbl carb, and short tube headers with a cat. I was told by friends to expect about 225 hp and around 300 torque. I think maybe a little less. Low rpm daily use street driver/cruiser. This mill may never hardly see more than 4000 rpm. Thanks.
