Well its that special time of year in michigan when the boats come out of the water and the end of season work begins. I picked up a formula 31 pc in need of new powerplants. Boy is my work cut out for me. No info could be found on pulling the engines, they are extremely tight and tucked back. Never the less i got them out and off to my builder.
I chose motor city muscle in clawson, and so far im happy woth whats in the works. These are mark iv 454's stock 310hp. Getting full long block build. The heads are peanut port gm's which is known to be leas than desirable and a point of concern of mine as im going above a stock rebuild. However ive found much documented data on successful port work of these heads so im optimistic. For a low rpm torque monster these are actually going to do me very well and i plan on having the engines dyno tuned so numbers will support my claims.
Long block rebuild
"stage 2" head port and polish
mild cam grind to match
performer intake
roller rockers
should put me in the 450-500 range around 3000-3500 rpm! Wish me luck, 13k is what im in for so far. Im sure more to go.
Now to pull my fuel tanks, strip the bilge, clean up wiring and replace ever hose i can. Pulling gen set for cleaning repaint and a new mounting plate. New ss mounting brackets for trim pumps. New bulk heads and heat sheilds. Replace bilge blower tubes.. ect. So much work to do in the end i hope its worth it. Cant wait for next season and drop in my new engines turn the key and figure out what kind of props im going to now need!
