Intake Manifold Rule

Not sure where you're going with this, Rick.
You can block off heater ports on an intake.
Also , you can block off w/p bypasses with a plug . Of course, it can be done at the thermostat housing (i.e. Olds, BBC) or at the water pump or block..(SBC).

Old school ideas persist. Sure, some are ok, but after having to test everything Pete McCarthy and other known back yard specialist ever said I found out 98% of what they shared was home grown myths. Which is understandable.

But, I want equal heat in the chambers. You do too. A hole only the size of .100 thou will transfer enough water to get the job done. I'll hazard a guess my offset from the Xover to the timing cover is as big as anything you've seen. It retains the o-ring and carefully placed RTV. Mine is S/S so I can separate the X over.

Works on the S/S baddest Pontiac engine combination on the planet. Why wouldn't it work for you.

And you don't have all that fussing drilling and tapping and probably some grinding.

Won't be long. NHRA will allow Stockers to cut off the X over. Bet?

Thanks for everyone's input. The knowledge base here is second to none. Those of us that are new to Stock Eliminator ask some unusual questions sometimes, but we always get answers. Not always the ones we expect or even what we thought we already knew. Sometimes the answers bring even more questions.

Mark you have a PM.

That means you are willing to think and learn. That's a great thing.There's enough knowledge here to fill a library with what everybody has accumulated. It's not always enough to know what works, it's important to identify what doesn't work, hopefully before an expensive mistake gets made. Have fun with your Pontiac!
