Hi Bubbie,Well did comp. ck. on it with a 144 miles.120 in both cyls.Shoild have alot more than that,bored 10 over,pop up pistons,htcc heads,woods 9fg.cams.just dont get it.Any ideas. Thanks.Fattyboy.
Did you have the throttle open all the way when taking the Compression?
Yes 120 sounds really low But even is a good start.. Not sure on the modifications you have done.
What is the altitude above sea level where you are located. This does make a difference.
most engines will run at a Low 160, better with higher 180. Depends on lot of the build details. what pistons are they and how much compression do they say you'll have?
If your build parts don't match a PLAN, this Might be the problem.
If the cam timing and valve open and close is correct, the cam may be wrong for this build. The intake closes at 52,,,
I think this MIGHT be way too big of a cam to match the rest of your build.
Where did you get the plan for the BUILD parts. was it a working motor copy?
Remember a Big Cam Needs COMPRESSION to replace what it looses in timing... 52* is a Lot of timing and IF the heads and pistons Don't compress enough compression you will have Low compression. No power and I think that is what you have.
My thinking is a cam with 40*on an intake close would be more than enough.
get back with these answers and we'll go from there.
A cam change MIGHT be all she needs.
