Posted by Robert Bondi on April 08, 2001 at 21:51:51:

I'm on the verge of an engine rebuild of an E12 1977 530i and want to know how much is gained over my stock 3.0L by rebuilding my M30 block as a 3.3L or 3.5L. I know what
needs to be done from an E12 forum, but I don't have any engine specs. for E23s.
My blue book tells me I have 175 HP at 5500 RPM and a max.
torque of 188 ft. lbs. at 4500 RPM for my 77 530i.
I don't have any E23 reference manuals, so I was
wondering if anyone could tell me how much power and
max. torque I can achieve with the 3.3 L or 3.5 L
M30 engines. Thanks in advance.....
