IF i had a 38 AVS they would be a good bolt on having 3 feet between bulkhead and motors, this 15 or 18" though, no way. Everytime i wanted to do anything it would involve tearing all kids of stuff out, engines sit way lower in this boat than my baja. My son who works for me INFORMED me if i decided to put them in I'm on my own as he doesnt want to endure the pain either!

Id put some low boost prochargers in my scarab (i still have 2 m3sc's and aw 504 innercoolers) but im getting too old to contort my body around in bilge, squeezing all that between backseat and engines would suck donkey balls, i will buy whipples first if it ever comes to that.

I can totally see that. A buddy of mine has a 33 avs. I remember looking in his bilge one day at the docks, and immedietely thought " i do not want to work on that thing "
Awesome boats, but man , they are tight in the bilge. There was one out on west coast for sale, with #5 drives, that had to be really tight with trannys in there.

I have been watching this thread a lot because I have been working on my low compression 500/540 efi
was a 540 short deck , 8.48 to 1 , 525 efi cams , dart 345 123cc heads , 500 efi intakes . guess of 550hp
now with a little work .
no with the same shortblock , 540 upped compression to 9.74 because of milling heads from 123 cc to 116 cc and gaskets from .53 to a .41 . cams swapped to a custom grind from comp , intakes from efi 500 to a single plane and a 4150 quick fuel 1050 cfm . dyno tested 710 hp now !
