If a low head was installed on a later engine that came with a high head I was wondering what anyone experienced when it was tried?
1- I know compression ratio increased.
2- You had poorer circulation thru the low head thereby increasing heat in the cooling system.
3- Was there an increase in horsepower?
4- Did it affect fuel consumption ?
5- I assume it would be harder to crank by hand, what about with a starter?
6- With a 26-27 engine you would possibly have to modify the fan mounting or go to an older style.
Just kicking thins over in my head and wondering what would happen.
Thanks

Re: Low Head versus High Head
I've never noticed any difference, if there was it would put a demand on low heads but the only demand on low heads is for the T to be period correct if fitted with the wrong one.

The past is a great place and I don't want to erase it or to regret it, but I don't want to be its prisoner either.

Re: Low Head versus High Head
My 22 came with a low head and a 3-1 rear axle when I got it. It goes faster on level and downhill, however, need to use Ruckstell more often on hills or even starting out on a slight hill. The car has a low radiator and still doesn't overheat.
