I have used Autolite plugs in all my builds for the past 44 years but NGK seems to be the go to plug with nitrous. Brad Watt was gracious enough to get me pointed in the right direction but before I order several boxes I would like to pick other B1 guys brain. I want to start out NA and then slowly apply the juice after a week or two so I need a NA and nitrous NGK plug number. Thanks guys. Its a 200-650 plate system 1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27 Livin and lovin life one day at a time

I agree with this, I also ran -8 plugs at 15:1 and would have went to a -9 for a small shot of spray. Jim

The heat ranges run from 5 to 11, hot to cold, and are closer together than most of the other plugs. I've found with my 11 to 1 small block, I can get away with 8s on Drag Week, driving on pump gas, and then spraying at the track with 114 in the tank. My brothers like to switch to a colder 9 or 10 when spraying their big blocks.

Hope o place the order today and make some noise with this thing soon. 1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27 Livin and lovin life one day at a time

Just bring the Absolute Vodka Brad. I will bring my Diet Dew mixer. I ordered 10 sets of plugs today so that will get me started. Thanks for the plug numbers.
