At this point it has a th400 stock, the rear end is stock, and stock rims with 235/75/15. I woul like to hop it up a little between 300-400 hp would of liked more but tight on money. It is desapointing something that big only around 270 hp. Why should i get another block. Also what kits are good with good quality and a good price, and which ones should i stay away from
