Buying a SEA DEMON this weekend, what one?
 

Ok here we go again. I have decided on a Bary Grant Sea Demon. Since they do not make an 800CFM I am wondering if 750 is to small or the 850CFM is to large?

Heres the specs again, I would love to hear what you think.
I hate to throw away $600 on the wrong carb :eek:

454 MarkIV
.30 over
Comp Cam around 236 duration .050, nothing ratical
9:1 compression
Large Oval 781 castings

Thanks
JIM

You might as well ask what oil to buy. If you dont spin it over 5400 the 750 is plenty, the 850 is too big. Youll hear many other opinions.

850 is way too big.

We're all in agreement so far. I would say 750 also.

Thats the one.what Ing. system do you have because that carb likes a lot of base timming.I running TB IV and the V6 module to get my 20* or more base.
