Lowest profile accessory setup? Hi All! New to the forum. I am putting an LS7 in a Cayman and am curious what the lowest profile off the shelf accessory setups are? I am thinking that I will run an electric waterpump and PS pump. Curious what the lowest profile crank pulley and alternator bracket are? Thanks in advance!
LS4... Based on the drawing above, the measurement would be 0. The inside of the belt is just off the face of the timing cover.
The LS4 AC compressor is low mount on the drivers side of the block and used the same belt as the alternator.
Stock belt routing:

For benefit of the OP, the LS4 came in front wheel drive applications - so you're looking for something like an Impala SS (fwd, NOT rwd), Monte Carlo SS, Pontiac Gran Prix GXP, and I think Buick had one in some version of the LaCrosse. Many have used the electric power steering pumps from Mini Coopers or MR2s to power their racks.
I thought LS4 spacing was based on a completely different crank. Isn't the actual LS4 crank itself shorter? Might be difficult lining things up with an LS4 pulley on an LS7 motor.
