Raising a cowl by 2-3 inches
Any good tips on how I can go about doing this on a spare hood project on my own?
I have a few Ideas but I'd rather hear from someone more experienced in body fab and applications.
Any advice and input would be greatly appreciated!

Lots of different methods for anything. I'd probably cut each cowl off about midway in height between the upper & lower radiuses. For pretty much any fiberglass repair/modification you taper grind one surface about 1/2 the thickness through, lay up new material on that side, then taper grind the other side & lay on more material from that side.
pretty sure the ram air hoods are SMC type fiberglass. epoxy resin would bond much better than polyester & you want to use mat ,not cloth, at least near the upper surface.
Many different methods could be used to hold parts together while initially laying up new glass & several different things can be used as release agents.
An alternative would be getting some other smc sheet material, grinding it up rough & putting it to the inside using screws through tapered ground down area area & epoxy, then removing the screws when dry, rough up any exposed fresh resin & start laying new mat & resin on top of it. Residential fiberglass flush doors get cut out for glass & the skin material leftover can be used. A residential door distributor may be able to give you a 22 x 64 cutout section.
Just a few basic thoughts......
