Although it's only a couple of months old, DM gets a fresh oil change because dyno abuse is tough. We poured in 5 quarts of 76 Racing 10W-30 motor oil-that should take care of DM for a while.

2nd Series Of Dyno Tests
For each series of tests, we'll number them consecutively, starting with the last number of the previous month's tests. We'll also list the last test from the previous month so you'll have something to compare the new tests to. This month our first new test is number 5. Unless listed, no other changes were made for any test.

Test 4: Last test from last month. Weiand 8004 intake, COMP Cams 1.5 roller-tip rockers, Carb Shop Q-jet, COMP Cams 246PE cam (246/263 adv duration, 203/212 duration @ .050, .429/.438 valve lift, 110 lobe separation) retarded 2 degrees.

For a last stab at some extra power we installed a COMP Cams stud girdle for Test 8. It actually hurt power a little so we'll take it off next month and save it for when we have much stiffer springs and run at much high rpm.

Test 5: Install 1 3/4-inch Hooker Super Comp headers and Flowmaster 3 1/2-inch mufflers.

Test 6: Install COMP Cams 1.5:1 full-roller aluminum rocker arms.

Test 7: Install COMP Cams XE256H cam (256/268 adv duration, 212/218 duration @ .050, .447/.454 valve lift, 110 lobe separation.

Test 8: Install COMP Cams stud girdle.

Did you know that you can basically degree-in your camshaft using a degreed balancer like this one from Fluidampr? Since most dampers are marked off up to 60 degrees BTDC, it's easy to check intake valve opening right on the damper, as long as your timing pointer is dead on.
