273/ 2 barrel camshaft options

Welcome aboard, and thanks for the story! Beautiful kids too!
A Disclaimer, I am NO ENGINE BUILDER, but I can put them together, and from experience a low compression 2bl 273 can be overcammed VERY EASILY. That is exactly what I did and regretted it. That cam may be able to be reground? I believe Racer Brown Cams is known for that? Same with getting those lifters refaced. Any new stuff is a gamble, and I would hate to see you go thru the agony of having to redo it again.
Good luck, just a couple more options for you.
Hello and thank you for the response. I appreciate the knowledge and sorry to hear about your experience. That’s exactly why I am here, I don’t know what I don’t know, it seems that any aftermarket cam may greatly affect or upset the cam related components I’m working with. Until I hear from the machine shop I’m hopeful for a refrains and resurface with what I have, if not I’m reading more on weather the isky option would “over cam” the existing setup. Thanks again for sharing!
