I do not recall exactly, but do remember there is quite a bit of clearance, car is at my shop and I am home at the moment. Never had any problems with anything hitting or rubbing.all of the ones i have are iron head and gm always gave me a 15 .very nicely done,very neat and clean.how close is it to the ps box.i have the bigger fast box ,the one with 4 bolt cover?
Nonedid you have any issues not useing the purge tank.i have everything from the donor car but would rather not use the tank if i dont need to.i have a new 4 row aluminium rad.and was thinking of putting in a nipple for the hose and a bung for the low coolant sensor
