There are so many marine engine builders in Michigan it's really hard to choose. EVERYONE has good and bad reviews so really hard to go by those. To build them correctly the price is going to end up being close with no matter who you go with. Drastically lower estimates will either end up costing more before or after the build is finished LOL! Make some calls and visit some shops and see who you get along with the best.

Dave at Wesco replaced valve train after I snapped a timing chain last Summer on BBC blower motor, very happy with turn around, performance and value.

Nobody mentioned that place in North Miami, you know the best used parts money can buy?

When Darr returns expect a 2 paragraph reply on what builder he thinks is the best for his supercat motors or whatever nonsense is going on in his head.

and drum roll,,,,go cobra go broke.
you should trade those mills for some fresh rebuilds from kidapache,,he can hook you up.

Frank at scorpion ,
price ,,time ,dependable .
seems to have a good record .

Wow thanks guys for all the replies! Every time I start scrolling through threads on this forum I learn a ton of new info.

I don't want to spend $200,000+ on new power, just looking to make these current bowties (even) more reliable. Waiting on Frank to call me back and will discuss his workload and thoughts on the rebuilds. Sterling is still on the table.

Thanks again.

Sterling built excellent engines for me. Mike is a super guy to deal with and will use him again. He has a wait list as well as any quality engine builder shop does. Don’t wait much longer who ever you choose.

Sterling has has had some bad luck on the runs and yea it doesn’t look good when he breaks. Broke a snout off on a whipple last run nothing to do with he’s builds, just bad luck.

frank at scorpion is your best bet for what you want done does good honest work cant go wrong

I’m at LOTO and I had Frank build me 540s was overly impressed on the build!

^^^This. Eddie is the man.
