Default 63 MM Throttle Bodies

I have three throttle bodies and enough blades to do all three to 63MM... looking at interest. I was thinking $700 outright or $400 with your core.


Let me know

Probably 8-12 HP and better throttle response... most of the big builders did them back in the day Rippie, Lingenfelter I believe.. others might chime in

I would be interested, would it be ok to do on an all stock motor? Or not worth it unless upgrades were done?

You would need mods to take advantage; need to match the plenum openings to 63mm
