well I got the following figures:

Bore 70.61
Stroke 81.40

Gasket Volume 4.20
Ring land Volume 0.78
Piston Volume 12.00
Head Chamber Volume 30.00
Deck Volume 5.25

Do you think those figures are ok? do you get 7.1:1 ?

PS no slick answers!

lol we got our own post dave!! As for the deck height... I've been told there about that by two different sources but haven't measured my engine, I didnt remember to when I changed the head.

Sorry mark... thought I'd said it was a std engine.

Hello and welcome Popeye!

Well the bottom end is std... just with a Morspeed head.

The only things I have personally measured are the head and the pistons...

My sources for the other figures are Adrian Dodd and Simon from Morspeed. They have been building engines longer than me so I have faith in their figures... and I haven't gotten round to measuring my own engine as yet. Its only a cheap engine, in fact its unknown... I havent even looked at the crank!

no I've not... but I've just figures from experts, one of which guilds engines for a living....

what figures do you use for things like head gaskets, deck volume, ring volume???

I can upload the spread sheet Karl (aka doodmeister off here) made... but I can email you it...
