i've been considering one of his swingarms myself. was thinking a +4 or +6 and couldn't decide so thought maybe a +5 which he said he will build. i have the 2 inch extension on my stock swinger right now. lets see some pics of that 465.
I am leaning towards +8 just because of the powerplant. The previous owner said it will flip you ass over tea kettle in any gear with the stock blaster swingarm. The only thing is that with +8 I would think it wouldn't be as strong as a smaller stretch.
