Default spark plugs
What heat range plugs would you guys use on a motor similar to mine.
383 L98 with miniram, 10.4 comp ratio, run on 98octane pump gas.
Using GKR bkr6e, was thinking of going hotter to bkr5e, would this help or hinder anything?
Any hints or suggestions would be helpful.
Thanks

I'd go with the NGK TR-55 platinums. That's what I run in my LT1 and a lot of guys here like them, too.

I like the NGK TR55's. A great plug, for a great price (~$14 US).
