Spark Plugs

[jrod92]

I went to check my plugs and they appeared to be a bit white and burnt looking. I am currently running autolite 764 and was wondering if i should try a hotter or cooler plug and if so which ones. Also i think im running at 10:1 or 10.5:1 compression if that makes a difference.

Those plugs should be ok. If I'm not mistaken they are a race style plug.You may want to consider giving the motor a little more fuel. These EFI cars run pretty efficiently so the plugs always, at least to me, look lean.

Give it a little more fuel? Do you mean a bigger fuel pump?

Clean out the injectors and see if they improve would be my advice.
