here is a little 454 I am building for another RRR member. It is a 4 bolt member, .030" overbore, forged LS6 pistons, Lunati cam .550/.550 cam, short single plane intake. Should be a fun runner! here is the block still with the protective grease all over it as it came out of storage. I will let the new owner chime in if he wants. Enjoy![cl
