My 74 cuda had a bone stock 440 with ol heavy trw2355 pistons. I put on a set of Indy Ez stock port heads, a hughes 576 solid cam, eddy victor Int with demon 850carb, Hooker comp headers with 3' exh. I run 3.91's and i have a 3500 tci stall. I know some of my parts could be improved on and i still manage a 7.25 in 1/8th.(mid 11's) Im convinced that 7.20 or better is in it. This with stock springs and 275/60 M/T ET streets. So i would say mid 11's are very easy with a stock stroke 440. Trick is the heads, cam, carb, stall, gears need to match up.
