Ok I have a 70 Chevelle I just mocked up my ls with a 4l60e. I'm using energy suspension motor and trans mounts with the new Holley pan the plates I'm useing put my set up close to stock bellhousing location the pass side head is about 1"3/4 away from firewall and I'm useing the stock 307 frame mounts the oil pan is about 1"1/4 or so off of cross member with the inner tie rod grease fittings just missing pan. I also used the stock crossmember Abe just cut off the tab and re welded it. I'm at 4 1/2 * down on motor and can't go up on trans anymore or it will hit. I am running ridetech level 2 coil overs front and rear there complete kit but it's not set up yet. I'm concerned about my driveline angle at 4 1/2* down???? So if anyone can give me any help or insite if that will work or what I should do to fix this? Thanks Tom
