What is a 525
I am looking at a Cafe racer from 1989 that has 525īs in it.
Are they 420īs with a blower or do they have different pistons, cams ect. ? Cigaretteman |
With a cig of that age, it could be a Hawk or Merc 525SCs. They both have similar specs.
454 cid block and heads similar to 420 7.5:1 CR Weiand 177 blower Hollet 1050 (Merc) or 850 (Hawk) rectangular port iron heads, roller rockers 525 hp Velvet drive, TRS (usually) Both very good motors in my opinion. Gary |
Do a search for "525SC" you'll find all the onfo you're lookin for.
The Cig probably has Hawk engines. |
