Here is an option.
Don't bend or look around the rules. Keep your costs down. What do you win by expending ungodly sums of money on an 80 year old engine? This class doesn't excite me at all.

I agree with you, and it doesn’t exit me either but just look at what stuff costs these days. I am not talking about swap meet parts or ebay parts. But to be competitive you’re going to need them.
5 main crank, rods and pistons $4000
Girdle for the block $2000
Dry sump pump $1000
Titanium valves 800
Water pump $500
Cam and mag or other ignition $1000
To be competitive you will need a custom billet head $2000
Your already at 10K and haven’t done any machine work, dyno time or other parts, and it only goes up from here. Take a look at the V4F street roadster that holds the record, it has a custom cast head, and that couldn’t be cheap even if they paid themselves .50 cents per hour. I presume these rules were put because of three engines. But like I said before I give it a few years before something shows up that will test the rules again. Maybe I am wrong, but its an observation I have. For this kind of money I would buy a old cup motor and wring it. But some like the challenge of building the vintage iron. Tony
