Current mods listed below. I plan on using a cam at or above cc305 specs (prolly above), and running like 250/210 intake/exhaust for head flow (or thereabouts), and running Dynatech long tube headers. Also, if I'm making 350-400 rwhp ... would a bigger posi unit be better than what's in my rear now? i.e. the Auburn unit? I don't want to spend $2,000+ for a rear, but I want the rear to be able to hold up. Any suggestions welcome!

later

 

I think the clutch will support your mods. If your future plans include a stroker, Nitrous or blower then I would do it once and get a McLeod Street Twin.
