B&M BLOWER
1 Attachment(s)
What Can You Guys Tell Me About A 454 Bulldog With L88 Heads And A B&m Street Blower. About 500hp. Reliability, What Should I Look For While Test Driving. How Many Hours Can I Expect Before A Rebuild. Motor Has 240 Hours On It And 20 On The Blower. Thanks In Advance For The Help.

Re: B&M BLOWER
First off, a Merc bulldog was a tall deck 540, 500hp.
Second, L88? Are you referring to the high compression 427 heads? Sorry, my corvette background is showing through. |
Re: B&M BLOWER
There is not a 454 Bulldog. Merc made a 540 cid, 500 hp Bulldog. I doubt that this engine is a bulldog. It has factory cast iron exhaust. I'd walk if it wasn't really cheap.

Re: B&M BLOWER
It Was Stock 454/b1 1990 Henry Keller Added The Blower And The L88. The Boat Is A Great Price. Just Dont Want Problems.I BELIEVE IT IS A BULLDOG COPY BUT THAT IS WHY IM ASKING YOU GUYS.

Re: B&M BLOWER
I'm not sure...Maybe the L-88 engine ran the 188 {Open Chamber,Rect Port} head.....
At 500hp i would think the boost is pretty low. Thats a good thing for long life. |
Re: B&M BLOWER
The only L88 I know of are the aluminum rectangular port heads used on late 60's corvettes. Kind of old tech.
BTW, you cant turn a 454 into a 540 bulldog. Different blocks. Get full specs, block and head codes, type of blower, crabs, cam, etc... Then someone here can probably give you good info. Gary |

Re: B&M BLOWER
Get the cam specs, the compression ratio, model of blower, blower pulley ratio, psi boost @ rpm, engine block #s, head #s, ask if the carb is boost referenced, and make sure all the accessories are USCG approved (fuel pump, flame arrestor, alternator, starter, etc).
I've never been much of a fan of the L & S extension boxes. And note bravos are not the strongest drives for a blown engine. Check the gimbal for play too. Gary |
