Re: LS-6

The three holes are there. As for the oil pressure fitting. what size should it be? The gauge tube is still attatched to the fitting that was on the block. It looks like it was pulled straight out of the block.

There a couple of suspicious items, you mentioned. The emission sticker would indicate a LS-5. The 3:70 ratio with M21 trans would indicate being standard for a LT-1, or possible optional ratio for LS-5 ordered with M21, as AC was not available with this combo. Without some factory or dealership paperwork this would be a tough call.

Joe Lucia is correct, 3:08, 3:36, & 3:55 ratios for a LS-6 with M21 trans. LS-6 and M22 combo could have above ratios as well as special 3:70 or 4:11 ratio. Is there a dual disc clutch/special flywheel with this car?
