Anybody have specs for Rover pistons? I'd like to have the compression height
and dish cc.
Now the whole story. 88 RR engine. I had initialy bought Keith Black
Silvolite pistons (at least I think they are). When it can time to calculate
the compression ratio. I came up with 7.775. Ugh, I know. I asked for
pistons for a buick at the engine parts warehouse.
Here are my numbers.
Piston dish: 14cc
Combustion chamber: 34cc
Headgasket. .045" (Felpro composite)
Deck height .067"
My brother says that deck height is no good and that I need to get it lower.
So what happened. Did I somehow get 8.13CR Rover pistions, then with the
thicker felpro gasket it took me down to 7.775? I thought Buicks only came
with 8.8 and 10.5 CR. Do the buick heads have a different volume?
Assuming all my measurements are right, what next. Should I get some rover
pistons?
What CR should I go for? 9.35, 9.75? I'd prefer to run 87 octane.
Who has the best prices? Rimmerbros has a set of 9.75 for $288 with rings and
pins. RPI $256 with rings only. I wouldn't need the rings, as I have a nice
set of Moly rings already. Any good sources in the states?
