Hp estimation
I've been wondering this for awhile it's a 355 flat top pistons comp cams flat tappet thumpr cam advertised lift is 297/279 the heads are just the Tbi swirl port heads but they have been worked a little 2.02 valves stiffer springs for the cam I know the machine shop worked them a little bit not sure exactly what they did has 1.52 roller rockers edelbrock performer air gap intake Holley 600 carb has headers not sure what brand or size they were already on the car if any other info is needed just ask I'll do what I can to answer the questions

Vortecs will be a huge gain over the TBI heads

Re: Hp estimation
Take those heads off and throw them into the nearest river,,,that's how good they are..Or sell them to one of "those" guys that believe theyre Vortecs because they use centerbolt valve covers......
