408 stroker vs. 500 stroker Challenge fun!!

i have 10 grand in my 408 stroker you see in my avatar....definitely could have been done for 8, but figure 2 thousand of that is going on the dyno 2 times, (2 setup fees) and an engine tear down, (diagnosing the problem, and replacing the bad lifter that was brand new)...and a brand new demon carb that needed to be rebuilt, rejetted, and gone through..ill give you my combo shortly. gotta go to store.
