RustyRatRod's Guide To Hot Rod Bliss

ok, now to throw something in the mix for change.

In this thread I get the sharp vibe that hot rod bliss is synonymous with a well tuned V8. That is cool and all but to some people hot rod haven can be reached with a slant six.

What would you do to be cost effective but warm up a slant six?

I understand this is a tall order because I have a Clifford header and 4 bbl. set up and I can tell you first hand that is was not cheap to buy it all new. :protest:

but assuming someone does not have a big budget but has a slant under the hood and a lot of time, what would you do to warm it up a bit. Not expecting a rocket but just some old fashion hot rodding with what exists.
