Jesse, sorry I'm a bit late to your question and this thread... Look for
Elgin Industries Cams if you haven't already decided on a source. They sell to machine shops, so your guy should be able to get whatever you need from them. I've also used Delta cams, but Elgin is a better deal (excellent quality and a bit cheaper). Delta quality is also excellent, to be clear.
A couple questions - Does the engine have a '54 block, or later? If it is a '54 block, was it originally equipped with a hydraulic cam (which only came on Powerglide cars in '54)? If it is an early full pressure block, and it wasn't originally fitted with a hydraulic lifter cam, the oil gallery to support the hydraulic lifters wasn't drilled at the factory. If it was originally fitted with a hydraulic cam, then the oil gallery is drilled, of course, and you have your choice of hydraulic or solid lifters/cam.
Hopefully not too late with this...
(You probably know, but just in case, the block casting number or stamped serial number on the machined pad just aft of the distributor can be decoded to help positively ID the engine, if you are unsure of its history. My mostly original '53 Bel Air with Powerglide has a '54 solid lifter engine in it, just by way of example on how things may have been changed 50 years ago).
Although solid lifter isn't what you asked, I prefer the 261 truck cam (Elgin # E-293-S), which is what Chevy also used in the '53-'54 Corvette 235's. It has a bit higher lift than the stock 235 cam, so the engine will breathe a bit better, without being an aggressive cam grind.
