Thanks Byron. I was measuring and making a drawing for fan shroud tonight and I will have to pull intake shrouds and radiator to fab so this may be a good upgrade also since I will have it all out.

On another note - I measured my pulleys tonight and my pump pulley is 6" and my harmonic pulley is a 5.5".. This means my pump is about 8%underdriven. Looks like I need to do something about that also. So I have to go with a 5 inch pump pulley or a 6.6 harmonic pulley? I am not sure I can go as small as a 5" on pump. The harmonic pulley would be easiest, but then I wil be speeding up alternator - is this gonna hurt.

The rabit hole keeps getting deeper!!! But it is a heck of a lot of fun.
