Just curious, but how can you tell he has a sniper from just a picture with no words?

Actually, I think I did it wrong with new , first post... I thought that picture would be my profile picture but isn't... And I can't see how to change that now.
With that full holley powered engine management, did you noticed a jump in power from the carb you once ran?
Or did I misunderstand

More refined power , easier start ups with wild swings in temps we get hear, and better gas mileage. I had some fuel supply issues and Holley fixed that too. Have dual tanks on a short box and switching valve Holley makes one that flows better then GM original which I was surprised... When describing issues I was having didn't mention dual tanks to customer rep but he asked me if I had it...

Anyways, maybe I'm still in honeymoon phase with Holley, but it's been good and with ignition control, even better response feel.

My 406 is happy, no over heating... No vapor lock... Etc

I just put new M/T tires out back, to replace the 275/60r15s I've roasted off... I see these 295/65r15s M/T SS and thought why not...

Wow, it's a much bigger tire then even I thought it would be. No fitment issues but my gear ratio can't be 3.77 anymore lol!
