96 lt1, whats the compression ratio with a complete lt4 conversion?
thanks
i know it depends on a few factors. heads were not ported, just lt4 heads. and assuming a common head gasket. or maybe an impy gasket.

 

The LT4 heads have the same size combustion chanber, so it will be unchanged.

 

cool thanks, what about if you used a impala gasket or another thin one,,

 

The impalla gasket is usually worth 1/3 to 1/2 a point in compression.
