That front axle is destine to get bent. That engine weighs 800 lbs and you can bend a front axle with the stock 4 cyl.
Not to mention the front has to be too heavy in general.
Where did they mount the radiator?
I thought a 4BT was only like 550? Not saying that isn't too heavy either, i just thought they were lighter.
check that out "750CCA industrial batteries" (which are group 31s) and the goon uses what looks like 4ga cable.
Hell, I have 1/0 on my 22R...
