Blower on a 454 makes a 525?
Someone said on another site that adding a 10-71 Littlefield blower to a beefed up 454 makes it a 525sc. Is the mercruiser 525sc not based on a 502 block?
Please give me your input.

NOPE !! A Mercruiser 525Sc is built on a 454 block. They use a Crane cam and springs and used a blower built by Weind I believe, and use a Dominator on top. A nice package built today would be a 4 bolt 454 with aftermarket heads, hydralic roller and a 256 Blower Shop blower. With this set up I have seen 575 hp thats reliable.

Firewalker, I am thinking of making 2 blower motors. If I have the 454/470 engines.If I were to rebuild them, and had Littlefeild 10-71 blowers, what specs would you go with to make the best combination for power.ie(lbs of boost,comp. ratio,cams,heads,lifters,pistons,crank)?

Yike,
I am an outboard guy, ask me questions there. I have a little knowledge with blower motors, but would not fell comfortable recomending anything, though I would think 10 71 would be big. 6 -71 would be better I think.

no need to checl spelling.
the 525sc was a 454 with 177 blowe ron it. I have 454 bored 30 over witha 174 holley and 1050 dominator and its run very well so far and has been very reliable.
