Since we are talking radiators, I was just doing layout for mine today. Here is the plan, let me know what ya'all think.

First off, the radiator is an all aluminum Howe, 2 rows of 1" tubes. The core itself measures 24.5" wide X 18.5" tall. I am mounting the air conditioning condensor 1" in front of radiator with the tranny cooler mounted directly under that, not over it. The shroud and 18" electric fan will be mounted with 1" of clearance from the core to allow air flow through the complete core. All air flow through the grill area will be directed to the radiator. Do you think that 1" of shroud clearance off of the core is enough to allow it to pull air?

I am running a modded 350/crate roller engine. No overbore. The radiator will be mounted in a custom frame set on 3/8" neoprene.
