98 rcsb build with stock injection

[copper98]

Looking for info on getting the most out of a stock L31/350 with stock/spider injection system. Just bought the truck and as best I can tell is basically stock. The owner I purchased it from had no info on truck. It is catalytic converter delete with duels and aftermarket exhaust.(not sure of brand) Other than that, who knows... I'm sure this has been asked before and I have searched and taken note of tons of possibilities. Money is not really and object(to a point) . It will not be a daily driver but I would like to keep the daily driver dependability. Just a weekend cruiser that will be running high octane pump gas. Interested in cam, head work, valve work, trans work, you name it I'm interested! Truck is in shop now having front end work done and a complete check up. Would also like to spray 50-125 shot so please keep that in mind with any info you give.
