Thanks for the reply, the sm420 sounds perfect. I want an bolt in, no machine work, no frigging... solution. I want the shifter to be where my stock one is.
The 283 is a 1967 from a C10/K10 with 2bl & PG. However I haven't been any deeper than the intake manifold; the starter, dist, heads, intake and carb are all numbers matching for a 1957 corvette 220 hp. I have replaced the intake with a Edlebrock Alum dual plane hi-rise, and Edlebrock 600cfm carb, added a Pertronix to the dist and the exhaust is dual with turbo mufflers and dumps just before the rear wheels (read low restriction).
It's not a race truck or a trailoring truck or hauling truck. Just me and perhaps a passenger, that's it.
Can I assume the sm420 was used on the half ton, 3/4 and 1 ton models?
Thanks again.
