then the plan is, lq4 bottom end, stock 241's with your polluter cam kit, ls6 intake, and full exhaust.
what kind of numbers should i be looking at through a m6??

Our polluter has made consistently 410-415rwhp on stock heads through an M6 with a LS6 intake with 380-390ft. lbs of torque.

I would look for the same horsepower if not 5-10rwhp more and easily match that number in torque.

This thing is going to be a BLAST to drive on the street! You will actually have a little more PTV room with the 241 heads on the LQ4 than a LS1 would.

With a 64cc chamber which the 243's have stock you would have 10.10 static compression while a stock LS1 has 10.32 static compression.

You could run 243's with that cam as it would have less compression and more clearance than a stock ls1 with stock heads.

This is based on a .052 gasket, piston .006 out of the hole, 64cc chambers, 4.00 bore and -6cc pistons. 4.030 bore would be 10.21 static compression which is still lower than a stock ls1.

SO with a cam as big as the polluter, would a guy need to upgrade the fuel pump and injectors?
