Reducing displacment to fit a smaller class?
« on: August 05, 2008, 10:07:25 PM »
Years ago I saw what on 1 side looked like a small block chev but on the other a ford flathead with a tunnel ram intake? They used the aluminum flat head to seal off the block on 1 side because it was now an inline four in a v8 block.Iam interested in techniques to seal off ports without welding, and how to balance out the crankshaft?.Plus longevity concerns! Bet these unbalanced engines really come apart big time if the blow!.

Gearheadeh, My father (Russ eyres) and I(Eric) built that motor and many versions of it over the years. We currently have two, one mech. fuel injected, and the 2nd is turbo charged with a FAST electronic fuel injection. Both have gotten records at El Mirage dry lake in recent seasons.They are stroked 350 Ci Chevy's, using the even side only. Standard 90 degree cranks, and conventional camshafts, motors are completely dynamically balanced, but are odd fire, so at certain rpm's the do shake!!! We have thought of building a new SB2 style, but to many current projects. for the longest time it was a easy 3 litre engine, but lots of new 3 litre alternatives these days. The flat heads covered an aluminum plate that bolted to the block and intake manifold.If you have any questions come see use at Bonneville( entries ,832,866,131,2) or look for a San Diego Roadster Club member, they will point us out. thanks Eric eyres

That's what I like about this place. 

Ask a (semi-off-the-wall) question and get the straight scoop directly from the horse's mouth (so to speak).  :-D

I wonder if someone in the future will use the new technology that allows your V8 to run as a 6 or 4 cylinder (in quite a few new vehicles) to change displacement classes, that is if you could prove that your is really running as a 6....maybe pull the plug wires?

I did it the old fashioned way.  Wanted to Run E/CGALT  but also wanted a Small Block Chevy Platform.  Hmm 265 was the smallest and not strong. (and still to big for the 260 cu. in class max)
 So to the drawing board.. Hmm Just get a SBC Block and Destroke the crank.

Our final displacement was 255.6 Cu In.   Runs good on the top end. Weak below 3500 RPM's  But pulls like a banshee from 4000 to 8400.. We are not sure about the longevity but hope she stays together for a few more records at Maxton and then B'Ville 2009 in a differnat Body Style.
