Speedmaster aluminum heads with 2.055 intake and 1.60 exhaust...
MP 590 camshaft.....Eddy Victor 340 intake worked on my IMM
Pac 1903 springs...Crane 1.5 rockers...MP race electronic distributor with MSD 7-2 I think..

This is a spare motor until the 408 get finished...this short block with Eddy heads ran 10.31 at sealevel....my guess it could run the same again...
in fact I had two sets of aluminum heads ported by IMM...one Eddy and one SM...flow sheets were identical...
maybe he was saving paper...lol....actually they varied a few cfm....
