Nice! Haven't seen too many optimized strokers lately with small cathedrals. Should have great throttle response and tip-in.

Lost about 15% tq and 16% hp.. What I find most interesting though is the different peak tq/hp rpm. Peak tq moved down in rpm by roughly 750rpm and peak hp also dropped down about 400rpm.

Congrats! 522/480 through your 4L60E and Moser 9" is great IMO for a 402. LME has always built some stout combos.

How is drive ability?

The heads were from TEA a few years ago. They had their normal CNC on them. They flowed at .600 324 Intake and 269 Exhaust. The only other items were the lighter intake valves and powdered metal guides so I could use the stock rockers with trunion.

Hope to get the car soon.
