chris , i have 410s in my blk 90 with ported inj housings and plenum,jeal headers, spin tec exhaust with dr gas x pipe, fidanza flywheel , car on drs has run a couple of very high 11sec time , runs 12.10 30- @ 119.85 to 118.00 all day long. there are 6 vids of my car on u tube if you want to see what the result is . under bradley taylor zr1 @ famoso car gets 24-26 mpg on the freeway cruizing between 75-80 . i have 3.92s in my callaway 475 snat zr1 that just got headers runs about the same times but 3 mile an hr less and gets 25-28depending on if i have the cruize control on . the black car gets better gas milage now then when it was stk (22-24). on injectors you dont need bigger ones until you get into the 415 zone . there are those who own them who are running the same size as stk . if you have the factory inj still in you car getting them replaced really helps out . jeff would know better on the ignition if there is a way to upgrade it . hope this helps .
