Initially I had about 3.5" of clearance between the wp pulley and the rad. I'm looking for about 5". Rather than buy a different accessory drive, I decided a 2" recessed firewall was a good option. So I made some rough cuts, bolted on the trans, and blocked it in position.

what radiator did you use? I have same combo but also want dual elect fans and not finding anything that I think will fit. my firewall is not cut but the motor is very close.

I used speedway’s 19x22 universal rad w/ pass inlet/outlet. For the fan I used a single hayden 16", that’s one thing I’ve learned, not to skimp on fans. I only use hayden 16" now.
