My body work and paint is nearly complete. Now I need to find a good 351W block and a tremec 3550. I am going to be installing a 393 stroker kit into the block and I plan on going with AFR heads. I was wondering if the 1974 and later blocks would be better b/c of the taller deck height. Then again maybe earlier blocks would be better b/c of their higher nickel content. Either way I would like to go with a standard bore which would give me plenty to work with. What's your opinion on the subject? Aside frome the local swap meets and classifieds were is a good place to shop around. Let me know if anybody here has a 351 they want to sell.
