Can anyone tell me the combuction chamber size in cc's for a 300-350 gas and LP head?

Dblair · Mar 2, 2011

I figure it has to be 77cc for the Lp and 107 for
the gas. the lp is 9 to 1 and the gas 7 to 1
according to Nebraska test using a gasket thickness
of .07 . just a close guess ( I hope )

If you shave .225 off it is 72cc just saying...

The gas head in stock form is 110cc

(quoted from post at 06:11:39 03/03/11) You just ruined a good head, and to top it off are dumb enough to advertise it

Go troll someplace else.

Well you can either run your sorry @SS mouth or ya can give some useful information! You guys are funny, full of talk behind a keyboard, a big pu$$y in person that has to pay someone else to put their stuff together cause they don't know a socket from a wrench!

Anything else useless to add?

You don't have a clue. Milling the head to gain compression will only weaken the head, when it needs to be stronger because of more compression.
So basically you are building a time bomb. Have you ever seen a combustion chamber break out under full load & RPM'S? Not a pretty sight. I am posting this so the home built engines learn NOT to mill the head to thin. If I made you mad I am sorry.

Maybe don't come across an a smart a$$ for starters! The 300 gas head I milled down that far still had .140 inch deck for sealing it! The block is partially filled and very custom. This isn't a plow all day kinda tractor or parade tractor, it gets fired up, hooked to a sled, run open, and then shut off! The reason I posted it was to show that if you are careful you can get a smaller combustion chamber (higher compression) without huge domes or expensive LP heads! The head has been on the motor for a few seasons and no problems! Not saying your post doesn't have Merritt either. You DO have to use caution any time you are milling that much off! Just with some careful planning it is possible. Why can't we all just get along! Lol
