Grand Prix Mechanical Specifications
(Thanks to Reptile for sending me the information)
The information is based on the L32 but should suffice for most anything to do with the block and rotating assembly on either the L32 or L67. If there is such specific information for the non-supercharged engines (if it differs that much), then if someone would be so kind as to send it to me I will get it into a document and post it up as well.
