WHY are you still running a mechanical water pump? With an ET goal in mind, that ought to be the first thing to go.
Cause it fits, and when I upgrade the electric 35gpm one on the Hemi this year with a 55gpm pump, I will have one...I can put on there. I am sure I will have to make all special spacers to make it all fit though. Winter has been too cold to do it now.
Those comp cams rockers, are they bushed? If not I would not run them. Steel on steel will gaul with roller cam spring pressures. Without thinking I ran a set years ago, comp cams. only .625 lift. Got one pass and several of the rockers were gauled. You might want to think about it!
Rockers are bushed....I like them a lot so far. Wouldn't use them if they weren't bushed.
Porting your heads will probably get you to your goal. You can try tightening the lash also, that might be worth something if the cam duration is less than 280 @ .050. Any place to scrub a pound or two off? Every pound is worth about .001 ET.
We will be looking in to it next year. Heads are fresh and ready to go.....Prices for porting were pretty high I thought, only so much money to go around.....
