Hey,

Is it better to have hot air going into the engine, or cold air, and yes I am aware that hot and cold is relative, but I think you will get what I mean, heat for example will be hotter than normal intake air because piping has run near exhaust pipe for example.

I believe the fuel should be hotter, to help with the combustion.
But I thought it would be better to have a colder air intake as the air will be more dense.

Thanks!

Things work best when the intake air temperature above the carburetor is between about 60°F and 100°F. That's what the '70-up thermostatic air cleaners are calibrated to provide to the carburetor. Leave the "heat for vaporizing fuel" job to the manifold heater.

Too many people who were born on third base actually believe they've hit a triple.

Thanks, That seems like it should be a fairly easy goal.

Planning to run my air intake piping to the filter past the exhaust manifold I have, hopefully to get within that temp range.

Going to have lots of fun with piping on my hoilday break!
