this car....
 

how would this combo work out? emmissions legal? it's a 1989 carbed notchback GT (LX with a GT body kit, and a saleen wing) how much power? are the windsor jr. heads aluminum or iron?

here is the combo: Ford Coupe 306 Five speed, Quartz Metallic, blue interior, 306cu, Windsor Jr. heads 194,160 w/ exhaust porting, F303 cam, Comp 1.6 roller rockers, Performer intake, Holley 750 mechanical secondaries, K&N, Shorty headers, Off road H-pipe, Flow master cat back, MSD ignition, all braided fuel line, Holley blue pump, 373 gears with new posi, Saleen wing, cobra rear bumper, GT ground effects, all new shocks, struts, calipers, rotors, bearings, bushings, inner and outer tie rod ends, tachometer, oil pressure and water temp gauge mounted on the A pillar.

also, does anyone make a supercharger or blower for a carbed 302? i know someone does, but im too lazy to look!

Forced induction is something I researched for my 85 carbed car, just so happens a friend of mine works at the ati procharger head 1/4's, I think a p-1sc kit was $4100, and thats with an intercooler makes like 14-20 psi, forged parts would be a must I do believe, car doesnt sound like a bad combp to me anyway, maybe mid 12s if I had to guess?

Putting a carb on your 89 is not "emmissions legal" Not even close.
