3K was to include +2+1 control arms and accompanying component's .. Aswell as +2 swing arm.. I'm not exactly sure I could handle a 421 cub? Idk ? Why I figured start with a great foundation, can always yank the cylinders and head to do top end work and porting.. That's where the powers at, if i'm not mistaken...Correct? Wanting to go to LS* Little Sahara* this summer.. Don't exactly want to be left behind... But definitely would like something I could trail, wheelie my pasture air out and maybe a few drags. I had plenty of fun on a stockish one, just not wanting to build something I wont/ cant ride often.
