Thanks for the replys. Thats what I get for typing off a description handed to me on a sheet of paper from the "self admitted" wild and crazy space kadet previous owner HAHAHA. The engine has been at my shop (I do alot of turbo smallblocks) since it was pulled from the dyno at Grimes. I building the turbo setup on the newer hotrod. I just talked to Garry Grimes himself and yes it is a B&M megablower 420 and he says depending on the fuel used it can make easily north of 800 Hp.

Based on searches on this website the Megablower 420 has pretty darn good reviews

Anyways, taking some more pictures for you guys. I admit im not a blower man, but thanks for the corrections.

Good blower, very efficient. Some parts a little hard to come by so just stay on top of maintenance.

Engine is sitting in the lonely corner waiting for a new home. Ive been doing Turbo/centrifugal forced induction LSX platform motors for many years, any specifics on those engines I can gladly help as well. Have done tons of setups from methanol, ethanol and various boost and compression ratios/pressures. cannot wait for the 400+ cfm 4v mercury heads with the structural integrity to hold the head down under boost. (our main issues Minus billet heads and 6 bolt layouts)

okay.. just so I'm understanding..So it's basically a stock 502 bottom end with some ARP hardware..Correct? Has the block been bored? Crank been turned? Was the roating assy balanced? Also can you give me some more info about the heads and valve train..Size and brand of the valves,etc..Thank you
