427 bbc hp guesstimate

[CreditGod]

With that small hydrolic cam no way will you see 450-475hp

to get into the 500hp you need to go with either solid lift cam or a full roller cam and when you do that you better get a set of H-beam rods (4130 steal) and a good set of forged pistons if you want it to last

My dad lives in east texas if you want to get any advice a real estimates he build about 30 high performance motors a year

let me know
