anyone see any problems with running leaded fuel through a zz4 350 chevy? l can get 110 race fuel from a guy for just a little more than l get premium from, l don't plan to run 110 on the street, obviously but, for the track it would be a nice treat.

are there any problems l would face mixing 110 leaded with 93 unleaded to come up with about 100-104 octane numbers? does leaded mix with unleaded well?

any chance in damaging valve seats/faces? there are no electric sensors on the motor to damage, its a 4 bbl non ecm car.

thanks in advance guys.

 

Ya won't gain anything from it. 93 unleaded is plenty for a zz4.

 

thanks jester, but should l ever have any reason to run it, would it do alright in the ZZ4? say with a little spray, or boost from a blower?

 

As long as you don't have an O2 sensor, leaded fuels will cause no problems at all...

The only reason to use that high of an octane is SC'ed though... Too much octane will slow the car down.
