273/ 2 barrel camshaft options

probably one of the biggest considerations is do you want to keep the cam as solid lifter?

that in and unto itself doesn't really dictate anything except for your cam and rocker gear, it's just a matter of personal taste and whether you want to keep it *exactly* as your pops had it. and the task of finding a solid cam that is a decent grind and not $$'s.

the budget seems to be steering the ship, so in that manner i'd throw down with a melling SPD-20 cam and melling hydraulic lifters. this is basically a stock replacement stuff that is affordable and will work with the stock adjustable rocker arms and likely pushrods. you could go a little more aggressive on the cam, but you're hemmed in by cost considerations and the stock 2bbl intake & carb that you're likely going with-- but upgrade to a 4bbl intake/carb and then more cam choices are available.

you have lots of moving parts at this stage of the game. i'd sit tight and wait till the all clear comes back on the heads & rockers and then make my decisions from there. if you need heads that changes the direction of the build considerably.
