I am having the engine rebuilt (403 ) on the 1977 Kingsley I just purchased
and I need
advise. Is it worth while to install a new cam such as the CASPRO or ??. Do
i need to
do harden valve seats, my engine man thinks just do the guides. Are just
OEM type
pistons ok or is there a better choice. Is there any thing that we should
be doing
other than the std. quality rebuild? We will balance the new pistons & line
bore etc.
