Making power in a 289

[rbohm]

something else you might consider is stroking you current engine.
1: you gain displacement with out a weight penalty.
2: everything that fits the 289 still fits.

the biggest disadvantage of using the 289/302 block for a stroker is you are limited to an ultimate maximum ci of 363, and i dont recomend that combo for the street. a practical combo would be a 331 ci stroker, but a 347 with a 5.315" rod is not a bad way to go either. with a 351w you can minimize the weight penalty with expensive aluminum heads, and you can stroke the 351w out to a current maximum of 427ci. but you will need 351w specific parts such as headers, and intakes, and likely you will need to install a hood scoop expecially if you want any intake better than a performer intake.
