Thanks guys! Not an LS1 guy here. I built a 454. some information about Holley's Can Bus drew me in here and i had to join for that discussion and to contribute my code.
My rig is a 454 Mark IV with edelbrock heads (i wanted arps, but backorder), all the other stuff that goes with it, including a cam that hits harder than my stepfather. i tried carbureted, but F that! so i have sniper and hyperspark. its in a 36' rv that can weigh up to 23klbs if i am towing. its about 600hp at sea level, but my base is 6000ft, up to 11000. so climbing those mountains with that much weight and a slushbox makes a LOT of heat. because of that i have 2 radiators, with separate thermostats, one it 165 and 180, 4 heat exchangers for the transmission and still if the RPMs drop below like 3k, im done...
anyway, thats my story.

cam spec
2 grey heat exchangers are transmission, the center is oil. there is an additional smaller transmission exchanger under the air dam. it does a final pass through the primary radiator heat exchanger. i think i am going to bypass the water for summer months.
the rear radiator is 5 row all aluminum and is run as the aux at 180f. the front radiator is the primary and opens at 160. it is capped at 24psi.
you can see the tee that splits off to my 2 thermostats and radiators.
