Just asking purely from curiosity.
I should have qualified that...I don't mind using higher octane fuels for WOT/track time but for getting to the car shows or cruise nights...I would like to get around without the fuel hassles. After speaking with the shop they're targeting a 10-10.5:1 compression ratio and depending on how the final cam selection turns out, this should make it for street driving.

The reason for my comment there was I've already got a motor with a lot of parts not appropriate for street use. I had considered tearing it down, doing a lot of work, replacing heads, replacing the crank (which has been turned several times), replacing rods and more. When I started adding it all up, and throw in the possibility for much more cubic inches...I decided to have one built from scratch.

I'm hoping to sell the existing motor outright (carb to oil pan, flexplate to water pump) as a runner. It's in the car, a buyer can come by hear it run and hopefully offset a big portion of my costs. I've also got a few sets of other heads, a reasonably fresh 350 short block (PMD), and some other stuff out in the shed. There's going to be a PMD yard sale in my future I think. If my budget holds out, I may spring for the aluminum block which will be nice on the front end.

If you or anyone has thoughts on the cam that would be great. The builder still needs to get me the final specs but I figured someone here might have been down this road already.
