Phil,
In working on my cooling (which most recently involved a smaller WP pulley), I wasn't exactly sure where I was gonna go. Twin pullers? Spal 16" pusher in front of my puller? etc. I installed the 70a relay so there was no question. If I knew then that what I have now is a keeper, then I'd drop in the 40a like you mentioned and be done with it.
Even though it's better, I'm not driving in mid day traffic in the Summer. I was going to try a 16" pusher with the stock puller but some said it creates issues in flow and could even make cooling worse. I'm leaving it as is but if that non sealed motor fails in the 30102113, then I may try the pusher/puller combo.
