Well guys... the winter is fast approaching.. and i want to have everything planned, exactly what im gona do and how im gona do it. Im really considering a stroker kit. I just really dont know much about the two. I kno the 347 will benefit from more cubes, but are the 347's really reliable? Ive heard they only last about 100,000 miles? Is that true? Basically can anyone give me a general set of pros and cons for the 331 and 347? Is a 347 the biggest you can bore and stroke a 302? Will a stroker kit be ok on my stock block? Thanks guys
