Yes the mounts have to be moved forward, Wayne Mr. Sub Driver will chime in with the correct measurement!!!

Uhhh, I'll have to dig it up from my posts somewhere,....Gotta put me on the spot don't 'ya Phil? ;)

I had it written down at one time, but that was many years ago ;)

It's all good, as I really have been wanting to review some of my old Ragazza postings ;)

Don't worry, we'll get it for you :D

Thanks guys
How about the exhaust? Will new holes need to be cut in ?

That's an important detail, as a lot more people will be looking at the back of your boat once you're done. :cool:

The width and height of the engine is the same, so a lot of it depends on your manifolds, if you trade stock for stock manifolds, they should be pretty darned close.

The link above shows what my measurements were, but it's been a while,......

Hope that helps, and remember, measure twice, cut (drill) once ;)

when you move the forward mounts up just move the back hole mount to the forward position and then drill just one more hole forward of that front hole which will now be the back hole .. hope that makes sense ! I did the same conversion as you are doing ...

That's what I ended up doing with the Ragazza too, BUT, I didn't (don't) want to bet on the mounts being the exact same from the Ragazza to a 16.

What about a hot Vortec V6!!!! Buz is waiting patiently for someone to build a Screaming 6! With the 6 you can still get at the front of the engine, the 8 draws a lot of blood!!!
