I'm putting a 6.5 na engine in my pickup which used to have a 350 gasser. I'm wondering what the best battery setup would be. Should I use one or two batteries? I think one would be easier if I can find a suitable tray. How many cranking amps are required if I use one/two?


Thanks

i would go get the battery trays for a diesel in that year pickup ( what year are you working on) and run two. If you really only want one it got to be a powerful one. I believe that my two batteries have like 700 CCA ea, so I'd say that should give you something of an idea what you need.

The truck's body is mid 80's; I don't know the exact year. I'll try for two, but in case that doesn't work out (due to space constraints caused be existing components that I don't necessarily want to rearrange), what cranking amps would be required for only one battery?


Thanks

'80s trucks had factory installed 6.2, with dual battery trays and cables.


The holes are already drilled, you just need the driver-side tray - goes where the emissions cannister was.


Fenders are not sturdy enough to run the high-amp big truck battery - will deform the well and warp the fender.


Not a pretty sight on an other wise clean truck.
