also have a ford cobra with a TT kit on it at 25psi he is making 1021rwhp with a stroked 281...which his comes out to a 302

i can keep on going, im not arguing with anyone in this thread but 650 has already been made from a 5.3 in this thread on the stock bottom end...as Quik stated Synergy did 850 also, no im not saying just anyone can do it but it can be done
