alright guys so i am new to the whole thread thing, i am building a 351 windsor and i need help so i figured id ask on here and see what everyone else thinks/ can help with. i have a 1969 mercury cougar with a 351 windsor, i already yanked the motor out and after closer inspection it is actually a 351 from a 79 galaxie so im already a little distraught as to how this will affect my build....area there any differences between the 69 and 79 block? i am going after power and torque like any reasonable man would and want to know where my build should begin... if you guys have any questions ask away
