compression ratio 3.5 dohc

[Monteros GC]

Hello,

which compression ratio have the 3.5l dohc engine in the 94-97 Montero sr?

9.1 or 9.5 if I recall My 3.8 DOHC built from a 2005 Galant engine with SR heads is about 11.7 or 12:1, It makes real good power.

Thank you! I found some informations that the pistons have the same part number like the european 6g74. So the compression ratio is 9.5
