I've been mulling over the placement of the radiator in the trunk and I think I've finally committed to it. I found a dual fan shroud for a mid 2000 chevy/gmc truck and figured I'd find a radiator sooner or later. Got that now. So I'm starting to do the mock up and playing with where and how I'm going to pull this all off.
I also found an aluminum boat gas tank a while ago. Seller claims 26 gallons.
To mount the radiator in the trunk I feel that I need to mount it in a shroud/duct by cutting the floor out and bringing the air in from the rearend area, thru the radiator, and then through more shrouding/ducting and back out the floor again. But this does not leave any room for that big gas tank. So I thought I'd cut the tank in half and mount the halves on either side of the trunk, in the pockets behind the wheelwells. Linking the tanks with a crossover. This way especially if I run E85. If I run pump gas, I might divide the tank two thirds and one third, pump gas in the two thirds and use the last third tank for race gas at the strip. I have to take into account the roll bar rear runners that will come down from the roll bar to the rear frame, so I have to build around that. I also made a deal on a Wenzler Tunnel Ram, so I am going ahead and working toward running the twin 750 blow thrus. Now the whole induction system will be a twin system. Mark L
