So i might be picking up a blower for my lightning swap this weekend. Unfortunately its the stock heaton... :( . either way its all i can do right now and want to get it so i can get the motor up and assembled and come back and swap blowers to a nice KB. my question is, is there anyway to check the quality of the blower, make sure no internal bearing issues or anything like that without having it installed on a motor and running? can i turn the pulley by hand and listen for anything. look for any certain signs etc.

please any help would be greatly appreciated.

i would pick it up and send it to posi for a port and rebuild. this will help you make good power with no additional issues. plus then you wont need a kb, a lightning motor isnt built to handle lots of power and a posi ported eaton with pulleys will put out as much as the lightning bottom end can handle

Wrong,

Anyway.

I just did a visual check over mine. Look at the rotors themselves and check for any obvious wear and damage. You can also check the fluid in the front case. Spin it by hand and see if she spins pretty freely.

KB on lightnings rip pretty hard. Iv seen plenty of those trucks push over 500rwhp and live a happy life. Just be carefull when its cold. I think my co worker is running 11.2 on his stock engined lightning and pushing around 600rwhp. Hes got some balls and hes also our shop tuner, but I mean his trucks lasted a while. Most of them though can make it to 500 and live pretty nicley. Just take a look over on the lightning forums.

i plan on going with forged rods and new pistons (maybe adjust the piston's cc abit to help with compression ) and doing oversized valves and maybe a light port and polish to clean up the intake and exhaust ports to gasket match and 3 angle valve job, to help her breath better. the engines already disassmbled in my garage and im trying to pick up all my parts then do all the machine work at once so i can assemble all in one shibang and not have to wait on much. I am lost when it comes to compression . i know they run 8.4:1 factory dont know what should be done after the head job new cams etc.. also plan on doing the 8 rib upgrade if 4.6 pulleys will bolt right up

Like any other bearing, spin the pulley and see if it makes any noises towards the front and rear of the housing. Should be quiet and smooth.
