Some of you may have read my other thread (http://brewcitymuscle.com/forum/showthread.php?t=36903) and learned that I'm going to rebuild my engine. I'm thinking about building a high compression 331. The reason I want to go to a 331 is because I found that most kits to build a 306 are the same price as a 331 kit. Also to my knowledge the block does not require machining and for a 347 it would. (Trying to save some money, and I don't hear as many people with 331's. I like to do things different.) Am I correct on this? I have been looking at kits from D.S.S, Scat, Eagle, and Probe and maybe one other I can't remember. I will be keeping it NA so I am looking at the kits with cast cranks. What stroker kit(s) do you recommend and why? What features/benefits/advantages do they offer? What is the "safest" compression ratio that can be run with pump gas (93 octane)?

Thanks in advance
