Best fuel for Stock - Page 2

Well I believe there's no one answer to your question asking " what's the best fuel and why". Depends on a large amount of variables specific to each engine, Carburator ( 2 barrel or 4 barrel) compression, timing, manifold heat etc.
Most find a fuel that's available , spend time at TNTs to get a tune up, jet size, timing etc that works for that specific fuel weight and vapor rate. Then they stay with it.
At one TNT session in my low compression motor and low RPM, I ran 92 Octane pump gas. It was faster. High octane generally slows the burn rate. My motor does not like slow burn rates, nor does it like
fuels with higher temperatures required for vaporization.
I would recommend , read the technical specification of each fuel carefully. There are differences.

Although there might be some general recommendations based on the combination, welcome to the world of Stock and SS: testing, testing, testing. You can't just read an article and/or go by what someone tells you. You want to go fast, better get on the dyno and make a bunch of test&tune runs.

Fuel Cells for Fuel Injected Engines.

Can a Stock Sending Unit to be bolted in it.
Or is an aftermarket fuel pump desired.

I was gonna use an edelbrock 110 mechanical pump

This is an over generalization but usually lower (mechanical) compression ratio engines prefer lower octane, faster burning fuels.
