I just read an article in April Super Chevy about a 1969 Z/28. It says the stock 302 was bored and stroked to a 383. That's a lot of boring and stroking isn't it? Well I guess it's possible if they say they did it but what will it take and is it worth the trouble? Is a 302 just a destroked 350? What is the difference between a 305 block and the 302? ---Rich
