I don`t have lm-1 but went to 37 squirter from 32 and my butt dyno noticed a world of difference,I had played with cam sizes and springs but the 37 adjustment made a world of difference.Motor was stock stroke with 320x590 isky cam shaft.Car went from mundane to downright scary out of the hole.I think you are using different manifold than stock too which I have factory edelbrock.If your using wiend or sheet metal manifold I think I saw you post a picture of I am sure your wayyy beyond what I have.I hadn`t found this website when I stumbled upon the squirter difference,magazines wouldn`t tell a whole lot back then either.I did this in early 90`s.With my cam I had to do something to help it out from idle and i had no idea what cam it had cause when I bought car thats what it had and previous owner didn`t know specs.I like your car too,hope this helps....
