I purchased a set of indy la x heads from brian at imm engines. after his valve job they flow 270 cfm at .600. my car has a 360 with 10.5 to 1 compression runs on 92 pump gas. mopar .528 solid lift cam, 727 with 4600 stall converter and 4.30 gear. 750 double pumper on a rpm air gap intake. runs 12.06 et's can't remember the mph but think it was about 112. thinking I can get to the 11's with a little more tuning.
