Give us some specs and let us guess what they will make. I hear Wesco's dyno gives "real" numbers so it will be fun to see OSO members estimates compared to actual.

454's +.040,9.6/1 compression,Merlin heads ,hyd roller cams,roller rockers,Edelbrock rpm intakes, 800 holley carbs, MSD ignition....blah ,blah,blah...should make gobs of torque.

My guess 535 HP @ 5400 RPM.

Did you option for the oil leak to not be installed?

Cord....people in glass houses should not throw stones! I can break out the sinking Cord pics again!!!

pulled the first today a little disappointing.....but stump pullers. I was wrong with the compression it ended up at less than 9/1 I'll try to post the sheet but its scanned so it may be too large a file it made 447 hp at 5200 and 500 fp of tq at 3400.

I was lookin for 500ish......oh well, the 850 would have drowned it we jetted it all the way back to stock out of the box jetting on the 800's and it was perfect. They burn 20 gph at 3400 rpm. i think the compression drop hurt and we could have went larger with the cam but it idles at 500rpm almost like a Searay! Its ready for a couple small blowers if I find a deal on some B&M 250's or talk Crazyhorse into some 420's for his mills that will get me close to 575......

Dyno/Don, I wouldn't be all too disappointed. They will be nice reliable engines, and while HP is certainly nice----just remember that TORQUE is your friend!!! Now get them in the boat and let'r buck!!!

Dyno,
In all honesty those are just good legit numbers. HP is calculation that needs rpm to make big numbers. I feel you will have a nice running boat once those mills are dropped in.

Sut I can email the sheet to you to look at if you like.
