okay...ditch the powersteering.
you dont need the cam gear.

get a used exhaust system and header.

spend the money on a maxbore TB, 3" intake and/or delta regrind.
after that, a nice tune (in which the cam gear may come in handy)

there was a cb7 with a custom exhaust, dc header and a delta regrind camshaft and it put 130hp on the dyno.

thats how important a good tune is
