no less than 93 octane should be used and u can do a pass and check the plugs for
color if they are tan all is good

Looking at a nice Pro Street car with 13.5 to 1 compression pistons. It
apparently has been at some statewide cruises, rod runs, etc, so I know it's

the engine to survive. Heard claim that by retarding the timing somewhat,
pump gas with octane booster works(?) Race fuel? Any ideas (...from guys
familiar with similar cars or situations). Thanks
Cast iron or aluminum heads?
Camshaft spec.'s
Carb or EFI
What might also help is what is the cranking compression of the engine
(Do a Compression Test)
I know a bit about cars, but not why the ?? about Al heads is
important- is it the fact it's Al and not cast iron, or just that Al
heads are likely to be better engineered?

Aluminum heads shed heat to the cooling system better than do cast
iron. You'd think that this would be a disadvantage, but in a high-
compression engine, it helps to prevent detonation. I have heard as a
rule of thumb that aluminum heads, all other factors being equal,
allow you to safely run a half point more compression on the same
octane fuel than do cast iron.
