Re: removing the secondaries a compelling story
Wow, Daryll... certainly not just a fluke, after having it happen twice on your motor. I'm glad my butterflies have flown away

Re: removing the secondaries a compelling story
I'd ask Pete about that D. He has probably forgot more than I know.

Re: removing the secondaries a compelling story
Here is the link for full pocket porting. I think I need to get my car to Mark and see what is truly done to the engine.

The way I read Marc's reply was that there is little to be gained in this on the LT5, and that the real gain from headwork comes in porting the runners. In fact, in that post, he refers to it as the porting goldmine.

 All heads benefit from porting. The real question does the cost = the potential gain. Your mileage may vary. Mine are being done at a local shop very cheap due to my sons friendship with the owner.

BTW when you decided to get rid of the wing I want first chance at it...
M
That would ruin my day. But aren't the throttle plate screws swedged just like the air horn throttle plates to make it impossible for those screws to back out? When I took my throttle body apart for powder coating the screws looked like they were screwed in through the rod then cut off and the tips of them looked like they had been melted. So if you back them out you will rip the thread out. And the screws were flush with the back of the rod so I could not just grind the swedged tip off and unscrew them without ruining the thread. That's why I had to tap them the next size up 8-32. I would think all the throttle plat screws would be the same. Unless of course some one had messed with them previously.
