Engine start stand

Guys,
I am building an engine start up stand.
Right now it is just a 2x2" steel frame on casters.
The engines will need to be started and tuned on this stand.
I am thinking about running electric fans on this instead of a factory mechanical fan for safety reasons.
Summit sells alot of options for around $50-75 bucks.
The radiator I have is a 22" core A-body but I can build anything to make it push or pull.
I am even open to a different radiator if necessary, but I already have a new champion 22"
What are your recommendations on this.
Yes I will do a build thread when it is done in case any body wants to duplicate.
Thanks
