Okey~dokey. A few tanks of gas later and pulled a plug. That small spot on the porcelain is just a spec of gyrotis from uninstalling. I don't think I'd be able to do any better than this with EFI. Timing mark.. heat range and ring all reporting good. I'll eventually get around to cutting a plug down to see what's up at WOT.. but she pulls really nice with the fun petal down and I doubt I'll find anything surprising. Think I can call it a wrap on this aspect of the project unless something pops up. Thanks all for the input and for following along!
Next item.. T/A hood installation.

I tried piecing together just the parts I needed but everything was out of stock. Last week amazon showed one kit in stock, then when I checked again they were sold out. Today they showed one in stock again, so I ordered it.
My kit arrived today. Looking at the card it appears that the stock primary jets must be 78's as that is the one missing from the kit. The 60/52 rod is also the one missing from the kit. I am going to Moparfest this weekend, which is about a 1 1/2 hour drive each way so it will be a good test. I don't want to pull the carb completely apart in case I mess something up and miss the show, so I will install the 64/56 rods and see how that works.

Finally I have a brief update on my carb tuning. I changed the rods to the 64/56 rods. I noticed a slight part throttle hesitation, so I changed from the green springs to the silver ones which step up the rods at 8 inches of vacuum. I had a chance to drive it about 30 miles today, and the hesitation is gone. I pulled a different plug and it looks a lot better. The plugs have not been changed, so they still have some soot on them.

The engine is a 361 with an actual calculated 8.5:1 compression ratio. I upgraded to a small cam which is essentially the same as the stock 383 four barrel cam. I figured due to the low compression I would stick with a hotter plug, hence the 14's. I am not up on the whole ground strap and thread reading. I could drop down to a 12 if that seems better.

So what do I look for to see that I have the right heat range? Also what do you look for on wide open throttle?
