408 blueprint motor 445 hp
I've read several articles about Blueprint's lack of quality and terrible customer service. A fellow I used to see on the board here bought one and had all kinds of trouble and they tried to blame him for everything including the 1/16" ring pack they installed on pistons requiring 3/32 rings. He finally ended up threatening to sue before they made it right and they made him swear not to talk about it to anyone or the deal was off. He took the deal cause he was tired of fighting. He told me about it via PM. Pretty shady co. if you ask me.
MRL is definitely a top engine builder but since your in CA I'd look into Brian at IMM engines. If I remember right he's in Indio and he's also a top notch builder. He's a member on this board also and goes by ou812.
