as far as i know the LA's handle the 4" crank without any clearancing at all, atleast thats what i thought...is this 340 going in your duster? should be a blast if it is!
Yes, it is 8) I'm pretty excited to start on it and hopefully charge somewhere into the 11's. Hearing a tech guy say "nope, not til it has a roll bar" would be music to my ears lol
You don't need to clearance for the crank..but if you go with h-beam rods you need to clearance for them,I-beams you do not..60 over deffinately have that block sonic checked..
