no replacment for displacement.......

BUT i was on a 42' tiger that had merc sc575s that were mildly modified up to about 650hp. They ran smooth as silk. Efi blowers are a VERY trick setup.

i'd think blown 502 would also be cheaper than a 540 or 572. Hell buy a crate 502/502 and slap a blower on it. A b&m250 with mild boost will make 650. My 461 with a small 174 blower (454 30over) will make 600 with a pulley change. WIteht 3-4 pulley it smakes 550.

Default Hmmm.

I would think a 572ci just doin its thing making
700 hp would be more reliable in the long run.

Vs.

a 502 with a huffer and a puffer sitting on top
Sqeaking the same power out.
Anytime your into the Boost your wearing parts
out. Radical cams and head work etc.


Downside is the Big swing on the talldecks
hits your wallet pretty good on your initial
investment. But I feel it will pay back in the
long run.


Hmmmmm
Just Do it.

502 with blower. A well setup blower will last as long, maybe longer as a big cube with same HP. When you tear up a big cube plan on spending big $ & time to get it repaired. 502 parts are off the shelf. Remember setup is the trick. Most people that you hear badmonth blowers had a bad setup.

i've heard afew engine biulders mention they dont liek to biuld stuff with these giant stroke becaue it creates wierd rod angle geometry.

one CA biulder sis poek with actully for turbo motors like de-stroked engine. Tka ea tall decka nd run a short stroke cam with low cpmression pistons and liek 25 psi of boost froma turbo charger. Becasu eof eth shortstroke he claimed you could easily (and safely) spin them faster. like 6500rpm with no prob.
