Need a favor from one of you factory big block guys

[jbristo67]

I need one of you guys to measure from the front of your block to the radiator. I am trying to figure out clearances for my serpentine system. Thanks in advance guys

I've got about 10.5" from the rad surface to the water pump mating surface.
I unloaded a stock 89 BBC serp setup I was going to use because of the lack of space.

i jave a gen 5 big block. i also used the gen 5 serpentine. its a tight fit but it fits really good. this is retaining the mech fan. idk if that helps much

On my setup with the motor in the stock location, there was no room for the '89 mechanical fan, I think there was less than 1" of room between the waterpump hub and the rad. It would have been tight for a dual electric fan. In hindsight, I wish I would have kept it and maybe shifted the motor back an inch or so, or found a dual fan that would work.
