Cam swap only worth it?

[jamesjones]

I'm in the process of swapping a cable driven LQ4 from an '05 van into my '72 Blazer. I've been thinking I know I'm going to hop it up eventually but I don't know if I'll go the FI route or keep it NA, so I don't want to get rid of the 317 heads. I'll also be using TBSS manifolds until I can afford to get some custom headers made for space reasons.

I figured since I have the front clip off and such easy access to the engine I'd have a custom cam ground and swap it in with some upgraded springs.

Do you guys think this would be a worthwhile side project to do to keep my right foot happy a little longer than the stock engine once it's up and running?
