Battery/starter lead gauge for 347

Just wondering if an auto spark could head me in the right direction for the correct AWG starter cable for a 347 equipped with a high torque starter. The cranking speed is producing a warm cable. The car came with 1/4 diameter cable or 6mm. Connections are all good with a high CCA battery. I am thinking a step up is required in diameter.
Any suggestions appreciated.
Al.

I always ran 2/0 6 volt cables until I bought a Robbmc starter, now I use 1/0.
I also remove any crimps and solder everything..

hd cables

Ford trucks with 460 engines used heavier gage wire cables. some parts stores will try to sell you the smaller gage saying they will fit.

I agree get a bigger cable, and don;t forget the longer the cable is you should make it bigger. So if you have the battery in the engine compartment you do not need to go as big as if the battery was in the trunk. but you should go bigger. I always go 2/0 from either place but 1/0 won't hurt, that,s on standard starters.

I also solder

Don't Forget the GROUND side of the battery. It must have equal size or larger cable.

Battery cable

Thanks to the above guys for their input. sounds like the 1/0 is the sure way to go here . I will take the advice given and solder the terminals as well.
From the AWG table i will go from 6mm dia to about 8mm or 1/4 to about 5/16. Thanks everyone for the input . Another step closer to the road.
Cheers from downunda
