ok so heres the deal. Im going to be driving soon and im going to get my dads chevy blazer. Its in ok condition, he doesnt treat it that well and i already know of a few things that im going to have to replace to get it back up to good shape. Im wondering if there is anything i can do to the engine to get some better performance out of it? anyone know of some aftermarket parts that i can get? it doesnt matter if its bolt on or not.. i know of a shop where i can work on the engine for free.

cmon someone please help!

which engine do u have in it?

4.3L v6

u can get k and n FIPK for fairly cheap, hypertech makes a chip but you have to buy premium gas (thats why i dont use it). edelbrock makes headers for it and pacesetter makes exhaust. holley makes a biger throttlebody, msd ignition.

how bout any internals? i think imma rebuild the engine
