what are the horse power differences between the 347 and the 331, ive always been a fan of the 331 especially becuase it wasnt as widely known, would it be around 350-375hp?

 

Unless you are going for a "max power" 347, the power lost to the lesser displacement of the 331 can be easily made up. The goal of 350 to 375 Hp should be within easy reach of either engine, IMO...

 

yea the one im looking at is a 347 stroker and its dyno sheet says 400hp and 400 ft lbs torque, ill call them tomorrow and ask if it would be possable to make a 331 stroker,

 

15 cubes is not much at all. Too many people place too much emphasis on too little displacement. It's not so much the cubes in strokers that actually make the power, but the increased velocity of the piston that generates a stronger pressure differential and draws air into the cylinder at a higher velocity(which results in higher VE). I like 302's myself, 3" stroke will take a real beating, and doesn't mind turning rpms. Different ways to make power, but larger displacement engines generally have an edge

 

im not worry about the displacement to much, its most likely going to be the same price so it really comes down to preference and the whole wich one will last longer, but then again, i dont plan i driving this car up and over 100k miles anytime soon
