northen auto sent me the wrong pistons so now i have the KB pistons with a 7cc relif and their 10:1:1 this is higher than i wanted but they said they cant get any full floating pistons in from federal mogul so they just sent me the pressed pins so be careful when dealing with them i guess i'll be running 94 oct an some octane booster but i wont be driving it much anyway so that wont be a problem will this boost my horsepower the slight compression change
