Hmm... I will take a look at the nail heads Buick's but I'm pretty set on something in-line or more than 8 cylinders. No matter how uncommon a nail head is, it would still look like a standard V8 to most people.
The more I think about this the more I'm thinking a 261 with dual carbs and making a Fenton type header exhaust for it! Probably balance everything and maybe do a little stronger valve spring to gain a little RPM.
I will also do some more research to see if the crank and rods from a 261 will go into my 235 block.
