Stock 360 with bolt ons - options

Is this a roller motor?
if hyd flat tappet
you can pick up your dynamic compression by using a cam that is shorter on the seat with a larger opening at say .200
not hard as the stock cam is long and slow and low lift
lunati 700 or 701 is about max without loosing torque
first run a compression check to see if you need a valve job
you need new springs and timing chain anyway, and new valve stem seals
go to any larger cam needs pistons, which help in any case, but a much bigger project, much larger and you need converter and gears, you have to buzz them up which is ok if you are into that
what is the number on the heads
the later heads with headers can use a single pattern cam
