Just a discussion we have been having on a setup
for my buddys new project boat
If you had a 454 with a 5psi roots blower making lets say
600hp and changed the shortblock to a 502 shortblock but used
same cam,heads,blower,everything from the 454 what would the gain of the
50 extra cubic inches actually be.
My guess is around 65hp and 75lbs tq due to the cubes and the unshrouding of
the valves due to the bigger bore
my buddy says because of the loss of boost on the bigger shortblock
it would actually be a smaller difference to the tune of 50hp and 50lbs tq
to where it would not be worth doing ..
Any real life experience with this swap anyone?
