Nick Williams isn't making them yet,
Katech ported
Tony Mamo ported
WeaponX ported
Katech 103MM, but way too much for a stock motor
Any of these places are porting the stock TB to have them flow better, some report a few HP gained, wouldn't buy it for that, not sure I really believe it, does improve the throttle response a great deal.
I got the Tony Mamo ported TB, the Katech 103 was looking at needed too much work to fit and until I build a forged 416 and turn the boost up, really don't need it.
It's not an old Vette motor, this is current platform Vette TB. Although I would suggest a ported TB from one of the Vette forum vendors. throttle response is so much better
My truck is CC and used the same shocks as I gave you part numbers for. I thought they were perfect for the drop and truck.
You were lower than me, so maybe something happened to them. I'm still using mine after removing flip kit and dropping the rear with shackles and block removed. Although it's getting ready to get dropped again.
I put the truck back to stock height with a level in the rear for an exhaust, now I pulled the exhaust off and going put the flip kit back on change mounting position in front again.
