Re: 406 sbc rotating assy

I always thought it was the "street" type applications of the 400 that needed the steam holes, as a more race type of engine had higher R.P.M s with it's associated higher water pump speeds and water flow that helped push any air bubbles or steam pockets on down the road so to speak.

Re: Race Engine Challenge II

For updates, there is a way to sign up for them on the race engine challenge home page if you want them to come straight to your e-mail address. I am looking forward to spectating and attending the conference there in the last half of this week.

Re: Finally figured out how to move some air on these heads...

As relating to the question " does CFM relate to power" someone has bumped up an older thread recently that has some incredible discussions going on relating to that very topic. The thread is titled " do hemi head ports go into sonic choke" or something close to that. Maxracesoftware articulates som...

Yes, you certainly can use a water jacket as an intake port as long as you are willing to use the intake port as a water jacket😬

Re: Ultradyne olds solid roller

Hoffman900, your link to Harvey Cranes site was very informative and nostalgic. The history describing the old days and the characters that were so innovative and enthusiastic is inspiring. Thanks for that link, it was so entertaining.

Re: Tips for storing blocks in high humidity environments

Like Modok said, I keep a block oiled up good. Every few months I uncover it and reapply the oil with my hands. A messy and time consuming job for sure, but it works. All machined surfaces get the oil.

Re: Static Compression VS Dynamic compression

What can help predict the fuel octane requirements of an engine are actual pressure sensors in the cylinder of the engine operating under the conditions you are expecting the engine to experience. Very expensive, but very fascinating and informative. I would like to have some of those type of toys!

Re: Static Compression VS Dynamic compression

Static compression ratio, dynamic or whatever ratio you can have information about is good in my opinion. The more information I have about the engine I am concerned with is a plus for me. I believe most people on this forum are intelligent and experienced enough to process and use whatever informat...

Re: Static Compression VS Dynamic compression

The "more overlap" statement must assume that more overlap equates to more duration overall that bleeds off some mass at low speeds. (Later I.V.C.) That is the only thing that makes it make sense to me.

Re: 380 ci sbc bending exhaust valve

Camshaft drive been inspected? Chain, belt or whatever is not letting camshaft retard is it? Camshaft degreed back in properly after the refresh? Will be interesting to fine out what is causing this. Good luck.
