Re: 347 stroker kit vs 331 stroker kit ?
go for 347ci. heavily worked 302 4V heads will get you up near the power you want, aftermarket are ideal but being a gt the stock look would be great. trouble is you will need a very non stock looking intake, carb, exhaust, etc to achieve that power, so maybe some painted aftermarket heads can be disguised enough. get back to me if u have any more questions, cheers.
