what would work for me???

Howdy y'all; I just finished an Lt1 swap into my 1997 K1500 here http://www.gmtruckcentral.com/articles/lt1swap.html , and lovin every minute of it now. but I have developed a blowby problem?? so now I am making plans to build a fresh motor for the 'ol girl. here is my quandry: I want to supercharge the next LT1, I think with reverse water flow and alum' heads it is a beggin for some huff. I will drop the compression, maybe to 8.5:1 or 9.5:1, with an end ratio of 11.5:1, or whatever the experts think is best??? I do have an extra M90, Knowing that it may not be enough, I have looked at the M112 and the M122?? looking for advice on how to procede. :teeth:

drop the compression ratio to the 8.5-1 and find a larger M122

i don't know of a factory manifold
there may be an aftermarket unit that will work or
you will need to adapt a manifold to work with the LT1

Dang!! I was afraid someone would say that!!! Ok you got it

way ahead of you there, going to "attempt" to take a factory intake, mill an oval/rectangle port in the top, build a 3/8 to 3/4 inch plate to match, bolt it on top of the intake, to mount the supercharger on. block off the original throttle ports then start adapting from there. sound crazzy enough yet???:freaks::freaks:

hay I got a chance to pick up a 112 with 10K on it for $300 would tha work???

that sounds like a deal,
why is it for sale?
off a crashed vehicle?
drive pulley also...

off a crashed vehicle? yup

drive pulley also... yup


what you think? go or no go ?? could resell it i guess???

should be good if not damaged by crash.
you have two issues
1. mounting the blower to a suitable intake/adapter
2. driving the blower, maybe with the stock accessory drive serpentine belt or it's own separate belt

how many ribs does an m122 take on most set-up? 8-rib?
