edelbrock magnum head valve springs

all great info. i agree with the split in jet size. the only reason the rear is so fat is i added a couple extra degrees of timing 37 total. my trap speeds are around 110 in a 2780lb car on a 28 tall tire. best et so far is an 11.99. my buddy has the exact same set up in a heavier car on street tires and is running 11.7s @ 116 with a 2.0 60.

i think im going to have a cam cut and upgrade springs. its worth the extra 500 bux imo
