I have a stockish 305 HO TPI...and i think it's got a peanut cam in it. I'm planning on building a 355 or 383 in a few months though, So I was wondering if I could buy a cam that would fit the 305 for right now, and I could put it in the 383 or 355 later on when i build it?
What do yall recomend?
Thanks

If it's got a roller cam then you are good to go. Get a cam that will complement the FUTURE engine and just tune around it the best you can with your current 305. Cam choice won't vary THAT much between a 350 and a 305.
If your engine is an earlier 305 that uses a flat-tappet cam I would not recommend resuing the cam once installed in the first motor. Flat tappet lifters "mate" with their specific cam lobes in only a few miles. Even if you make sure that you keep the lifters matched with their corresponding cam lobe it won't always drop right into the new motor and live a long life. The lifter bores in 2 different blocks don't always orient the lifter in exactly the same way over the cam lobe (they're supposed to, but production line block tolerances aren't perfect). That being said, I have personally resued the same flat tapped cam in 3 different motors without flattening a lobe- and I even switched the lifters for a fresh set in one of them! So it can be done, but don't depend on it working in every case.
