I am looking for a little assistance from my LT1 brothers and sisters...I am currently deployed and am wanting to order silicone adapters to have when I get home.

I need the ACTUAL outside circumference measurement of the throttle body inlet and the outside circumference measurement of a LS1 SLP lid outlet. I have a Arizona Speed and Marine 58mm tb, but it should be the same as a stock unit.

I am aware that a 3" fernco adapter will fit the throttle body nicely as that is what I have now, but it doesn't fit the SLP lid very well and more importantly, I don't like it. Also, I am no longer tuned for a MAF and and want to go seamless from my tb to the lid.

I have reached out to AS&M for help with no results so, thanks for any and all help with actual measurements!

Anyone able to pull a measurement off a SLP lid for me? Also, looking for someone to verify the throttle body circumference measurement...

Have a lid that's off-car, neck is 12.25" in circumference. I'll have my TB off in a week or so, so i can pull a measurement on that then, hopefully someone can chime in before then

Alright sorry for the delay but finally stopped by my car

12 7/16" circumference on the outside of an slp lid
12 7/8" outside circumference on a professional products 58mm (this was on the necked down portion were the clamp rwsides)
