Contact Tim at MPR racing. 561-588-0188. He has his own that he sells. He also suggested to be careful with Boundary. He has seen some Engines with them fail causing issues.
That maybe why they are so much cheaper. I paid up for tss in mine because that is one place I don’t want to cut corners or save a buck. TSS is the best for 3v. Only gear I’ve never seen fail in a 3v.
Alot of 3v folks have had problems with Boundary, me included. But if you post that on the internet, the coyote Boundary nut swingers will say you are crazy. Pay up for TSS. Totally agree with sportinawoody
The oil pump gears are the most critical components of the engine so if there's anything that you should spend the money on to get the best, it's those. TSS FTW.
