‘65 GMC 1000 305ci V6 Sm420, ‘66 C10 LS/480, ‘58 Biscayne 348ci/powerglide
I have heard of guys doing 265, 283, 292’s but any one ever try a 305ci V6? I daily drive one now and will be picking up another spare in about a week or so. Low revving, high torque, but also bulletproof. Wondering if I find someone to balance the crank if it would be worth an eBay efi and turbo.
