Thanks, I'll be pulling the 305 apart in the next few days, and checking it out. Then start looking for a reasonable machine shop to take care of the block, crank and heads. Unfortunately this is a project truck, so cost is everything, and the cheaper the better, but I want to only do it once. So I'll look into some rods, but may have to live with the 350 rods. This will be a basic stock 350 rebuild, with maybe a RV cam, and a 4bbl intake. With the SM-435, and rockwell from the 68 K20 and the Dana 44 and 12bolt from the 77 K-10, all under the body of a 1964 Datsun pick-up, I should be able to go just about any where and still get reasonable mileage with my 35x12.50x15's.
Thanks again, Garry K
