3.48 stroke here also a 9.025 block give or take a few thou.lefty o wrote:ive no idea how you can squeeze that long a rod in a stock 350 block without talking something like a 9.5" block with about a 3" stroke crank, maybe even a shorter stroke, and just a big bore...idk. an 8.1" rod in a 9.025deck block dont leave much room for piston pin height nor any kind of stroke on the crank.
I would bet they are special sonic welded with the rare under water flux using the special propiatory cobault carbon alloy then processed with diamond grain crystolization hardning tecnique? But thats just a guess I am probably way off. Just something i saw on the rocket labs documenity chanel loldwilliams wrote:I'd love to see some information about the welding job...
A move in the right direction but it still won't cut it.amc fan wrote:Wrist pin tucked under dome....with ring groove support spacers.
Now I am *really* curious. Stock "block" but one piece upper cylinder/head combo (so the effective deck height is 2-3" higher)?David Vizard wrote:Trust me here but these rods will survive the peak rpm involved for at least 500 hours. Also no head gasket involved.BigBlocksOnTop2 wrote:I would not trust it as far as I could throw it. Going to be using a .25'' thick copper gasket?

2" thick head gaskets have to be killer to make!David Vizard wrote:3.48 stroke here also a 9.025 block give or take a few thou.lefty o wrote:ive no idea how you can squeeze that long a rod in a stock 350 block without talking something like a 9.5" block with about a 3" stroke crank, maybe even a shorter stroke, and just a big bore...idk. an 8.1" rod in a 9.025deck block dont leave much room for piston pin height nor any kind of stroke on the crank.

I read somewhere that a large R/S made an engine less accelerative under load than a small R/S. Several engine builders I heard talking on the subject R/S said they got the same power out of a large R/S on the dyno as a small one but that at the track the small R/S engine was much more throttle responsive and accelerated much quicker.
So, why go for such a titanic R/S? Something to do with rpm and rpm range? Surely this thing is not going to be expected to rev all that high.....
That's... interesting. Especially if the short rod engine had heavier pistons, which I assume it would.Ratu wrote:Big, big rod/stroke ratio. Wow!
