Re: 302 rodded 351 or high comp 351?
Thanks once again mate, that's a fair difference in fuel quality. I'm going to take my time slowly with this decision! I can't identify one of the blocks I intended on using, so I'm going to try work that out first. It just has odd numbers and no serial.
Not quality, but how it's figured, like the different tempeture scales, 0 & 32 are both freezing point of water.
