Please share your experience with getting more horses out of the 60

[misterpoopoohead]

Hi Gang,
I thought I'd start another thread!
Have any of you rebuilt the 600 engines with the specific intent of
pumping out more horses than the 35 or so that they normally get?
If I were rebuilding a Ford 351 or a Chevy 327 I would know where to
go and what to do.
But, what are the details for the little 600 engine?
Do people bore them .040 over and then install oversized TRW pistons,
roller rockers, and a mild (or 3/4) cam? :o)
What about aftermarket carbs and K&N air filters, etc?
Please share your experience with 'souping up' a 600 engine.
My plan is not to race the car. I'd just like to develop as much HP
as possible.
I look forward to your answers and the discussion!
thanks!
