Comparison 340 / 289

I bought a 70 Mustang Grande with a 351c-2v from a guy who said the engine was toast. Turned out half the plugs weren't firing. Changed them out and it ran great. Had a FMX auto in it and chirpped the tires going into 2nd gear. Was a fun car. Now if I can only get my /6 1bbl to do the same thing.:cheers:
