69 Camaro questions ?

[Mucker15]

My name is mike I run ny5thgen.com a local camaro club here inthe tri state area , Freddy Sunoco twist is a buddy of mine and his car has inspired me to maybe do mine
This is my 69 Camaro it has a nice crate motor (360 hp) a Holley 650 turbo 350 trans 342 posi rear (79z28) hooker super comps
I was thnking about selling it and buying a grand national for something more family friendly I have two little guys etc.... But I think I might go the other route
My question is does it pay to just add an aftermarket fuel injection set up and do my suspension or should I go with a full ls swap , was thinking of a 5.3 because my car is a original 327 car or an lq9 affordability is a huge issue want something turn key and reliable
Any suggestions for motors ?

Also can I add a FI fuel tank before I go with an ls ? Alot of this project will be piece meal due to family finances so I'm trying to get as much info as I can before I start getting parts

Love the forum any help will be appreciated
Thanks
Mike
