btw i like your username. :P

 

just buy a 347 rotating assy for an early block............that will give you 58 more cubic inches which means at least 50 more hp/tq in your 289 block, add some cam/heads/intake and you can ad over 100 hp/tq.

 

289 (4.00 bore 2.87 stroke)
302 (4.00 bore 3.00 stroke)

I can argue both sides of which is better. From a torque perspective, the 302 is going to be slightly better due to having more stroke. From a horsepower perspective, you can rev the 289 higher with the right parts because it has less piston speed limitation due to having a shorter stroke. All things equal, the 289s horsepower will be at a little higher rpm than the 302. Remember horsepower is a function of torque AND rpm. If the torque numbers are not too different, you can sometime compensate for lack of torque by reving higher.

my77stang is right, tell us how much money you got and what you want your pony to do and we can help spend it for you.

 

You just want to spend someone else's money:P
