BIG QUESTION:

I want to rebuild the engine properly...and because I have to change many parts I would like to know from all of you which could be the best solution for money wise performance upgrades.

I was thinking about:
- changing camshafts (they are ruined, and I don't really like to reprofile and re-harden them) with some more aggressive units (I red about them around the forum and online I can't find anything clear).
Changing them requires to change valve springs? Is it better to run with hydraulic or solid lifters?

- changing cylinder sleeves, pistons and rods (I saw a 368 cid kit on Gerry's gaskest website)

- go for a stroker kit (if the crankshaft is ruined and needs to be replaced could be an idea, but I didn't find much about it)

Unfortunately I'm struggling a lot in finding parts and useful informations for this engine...usually the websites that talk about LT-5 haven't been updated for at least 10 years...
