Is it worth it to get the front main cap converted to 4 bolt with the middle 3? Also, can the stock pan be modified to fit with that front 4 bolt cap?

 

I've never seen a conversion that included the front cap. the center 3 take the blunt of the force because they gave pistons on both sides im sure it may be possible but I dont think its neccessary, hell 4 bolt main are only neccessary once you get in the 500- 600 RWHP area and there are plenty of cars running 700-800 with just the center three.
