supercharger for 89 350tbi

a friend of mine wants a supercharger for his 89 350 tbi pickup. procharger makes one but i can't find a price for it. tried ebay,jegs,summit and no luck. if anyone whos how much this kit is please let me know. If you know or another kit and price let me know. i'll foward any comments to him. thanks in advance.

if you are going to put a huge powergaining kit on there i would make sure he has a 4 bolt main block to be on the safe side. i dont know how true this is, but a friend of mine who knows his stuff told me that 2 bolt main blocks should only be used up to about 500 horses or less, and a 4 bolt is required for any more

its not my truck so i'll have to ask him. Its the stock motor if that helps.
He said he was looking for a supercharger and i found the procharger kit.
He just wants a price on a kit for this vehicle.

actually i think most of the truck engines are four bolt mains. im not for sure but i believe newer model trucks actually come with six bolt mains, with the extra two going diagonal or something like that. their pretty beefy. i would guess that even if it is a 2 bolt, you may still be able to use it because they are by no means weak engines

all im really lookn for is a price for a kit. preferably the procharger.
