I just got a 81 440 with a sized motor so I got a new/used 440 and I hav a PJS Inc. pipe coversion to make the exhaust come out on the right side below the water line. Also a bilage pump, and a PJS intake grate and a aftermarket impellor. Also what looks like a velosity stack upgrade, primerkit, and k&n airfilter. I have compression, spark, and fuel. But it wont even spudder
