I suur woud not spend a ton of money on head mods and the weeken the light wait casting by milling it for a little compresion. Compresion is good but not that important when you gotta start braking the bank, buying four dollar ethyl. But if pistons and the cost of boring is what Ive bean hereing, I dont think Id do eather. In reading dyno six stuff from the past, on the 261s (tho differnt) more hosses and tork come by way of ainches. So overalls I think Id relie on the compression resulting from the cilinder volum, an wile atit get sum big,(.060 r mor) kiler pistons. So you probably shud bore it big and wile youre at itget the highest comp they mak. Ya get too bangs for youre buck that way.

I DONT SMOOCH THE GRAND TETON!!!!!!!!!!!!!!!

I'll PM you something when I get back from Corpus thursday or so.
