engine build for reliability

360's go just as far and long as 318s.
With money no object I highly recommend a moderately cammed 360 with aluminum heads and cylinder pressure cranked up to 185psi, and a spreadbore carb. I got one of those to go 12.9/106 and 32 mpgs. OK wait, the 32 was with double overdrive lol; the final drive ratio was 1.966 lol.... 65 was 1530 or something.Unbelievable BB type, crapyurpants low-rpm torque.
