so i have an 88 f-250 that i did a motor swap on from a i6 to a built 351 bored 30 over with forged dish top pistons crane 260 solid cam solid lifters stock crank and has a holly 650 secondary vac carb.

if anyone could help me i need to know what would be more reasonable, a turbo or supercharger? honestly ive never built anything with either a supercharger or turbo charger so the more info the better. i would like to know how much hp gain each would give also if so and for turbos i was looking at the t76 becuase i saw people running them in 5.8 mustangs.

also last thing, i was wondering if someone could guesstimate the hp as it sits now, if i had to guess it would be around 360 370?

thanks!
