I am just wondering if the 4 bolt main deal is really worth it? I mean I have read all the magazine articles, books etc. on splayed caps, 4 bolt mains etc. My question is this, for a guy on a budget, building a decent motor that sees the drag strip a few times per year, is it really worth the extra? Splayed caps can run into some serious money and if you are building a 350-450 hp motor, with no nitrous or supercharger, would you be better off spending money on other types of insurance? Like better rods or a forged crank? I'm just asking for opinions here. Not wanting a brawl. And just for the record, I have only owned one 4 bolt main.
