Beautiful excal! I run the 177s and raised props 2" plus ground out some hook. It runs in the ninties typically. Suprises a lot of folks for sure which is quite fun.

That batboat is just sick chuck.

Here is one more of it .http://www.youtube.com/watch?v=FSSG-..._order&list=UL . What did you set your x dimension at?The bottom of my boat now is straight as an arrow. The guy who had it before me painted the whole boat even the bottom.

4.5" prop shaft depth.

What kind of boost and what is your comp at? I'm at 9.1,i know everyone says 8.5 or lower but my buddy tells me no problem.

9.5:1 w/ alum heads. These small blowers on a bbc work very well with higher static compression. I typically run 5psi with hyper pistons. This winter I changed to forged pistons so I will run my 6.2psi pulleys after the engines are broken in.

Great....:party-smiley-004:

Now I'll never keep up.:lolhit:

Sure you will Phil, BT will toast a Backyard Marine Bravo soon enough!

What up Dave!!?;)

Don't you mean "another" one?

I'm not planning to break ANYTHING:

Dude this has got to be your first speed boat...Your already saying how fast your going to be. Okay your Motor dynoed 700hp get it in the boat and see what it runs.

i have been on the water all my life but it is my first speed boat, btw im only 28.

I bet money that the 502 you had in it with the aluminum heads and the single plane intake with an 850 and headers made more than 500hp more like 550 or more. so get it in and see what it runs......Just sayin

rob, that motor barely lasted a week.

So its the big weekend?????? Any one want to play?
