Or at least post up the engine specifics. You still havn't said the CR or tune or anything. Kinda hard to assess what might be wrong when all you've said is "is a new engine and falls on its face above 4500"
Also, you need more gear. 3.73s are for girls.
provided the 5.0 owner can drive, and the others can't, it's prefectly plausible.
his engine maybe has 150 miles on it... it was a brand new long block... but his old engine with 189k on it was just as fast...wtf... both fuccckk up at 4 grand
haha 98cobrafaf has 373 and a t56 but at 70mph hes doing little over 2g in 6th gear... he wouldnt wana go any higher than that sense its a daily driver... we raced again last night and i beat him in my stock 5.0 cobra
all i can say is I WIN
all i can say is I WIN
whats all done to your said 5.0.
it sounds like your telling your friend not to race and then picking on him when he loses. the op sounds like he's letting his pride get in the way and possibly making some costly engine mistakes. you both FAIL.:nonono:
