my friend built a Mitchell engine for his '69 that was close to 600 hp.
the 3/8 fuel line delivery was not an issue. to install a STOCK fuel line correctly you have to lift the body.

There's a couple guy's in the C2 forums, who've done fuel line's with the body on, but involved sectioning/soldering it. This was really just to replace old/rotting stocker's though. Consider using a rear mounted electric fuel pump under pressure, with a front mounted regulater for more power though.

I did it on a 74 vette with steel lines but I had to do it in sections. I used 4' sections with compression fittings. It wasn't to hard, just get the car as high off the ground as you can

I would never section a fuel line. I would go to the trouble to lift the body (lift the body straight up 12" or so then back down) to install a one piece prebent correct front to back fuel line.
There is an alternative way to run steel tube fuel line however. you can use bulk fuel line that comes in a coil and can be snaked along the frame and formed as you go, also the body can be tipped (lifted on one side) which might make snaking the line easier.

I am in the process of running new line for my LS conversion. Did the gas tank need to be dropped to get access to the fuel tank fittings?
