I was chatting with my brother the other day and he was talking about engines. We started to debate which was stonger setup, a four bolt main block or a two bolt with splayed caps. I said the two bolt with the splayed cab was stronger than the four bolt. I was wondering who was right? /forums/images/graemlins/confused.gif Also, a 383 stoker is a 350 with a 400 crank and rods that has had some machining done correct? Odd question, what is magnaflux checking and how does it work? Is it worth the 100 buck a part to have them check?
