Re: Bore, Stroke, and block strength

2 engines of same displacement but one small bore/long stroke, other engine big bore/short stroke. What the small bore engine lacks in piston surface area is made up by the leverage of the long stroke. What the short stroke engine lacks in leverage is made up by the big bores' greater surface area o...

Re: Bore, Stroke, and block strength

Re: EMC 289

Very impressive build and so close were 1 and 2. Congratulations to you and your team, well done.
Also, you make a very interesting point with this engine, something besides a "400" cubic inch can put up some fantastic numbers on the dyno.

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.

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.
