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:
