Theres other, better, manufacturers.
With better attitudes, too.

who are we talking about?

DennyT apparently. I have never dealt with them but Mark must have and didn't find the experience much to his liking.

I heard that some modified fuel pins are case hardened and others(BD?) are not. Which brand/source of pins is regarded as the best hardened ones?
I read lots of praise for M&H M3 or M4 pins. I prefer a low smoke pin without massive torque increases because I have a somewhat delicate R46 auto trans.

M&H are spoken pretty highly of. i think denny t had a batch of pins go through that weren't hardened, but they took care of it for the most part

I had a great experiance ordering from M&H and IMHO there dynamic timing spacer is very under rated! it made huge differance in my truck.

on topic:I ground a spare fuel pin and this pin madea bit of a differance,more power from a rotated stocker,but with my WMO mix it smokes tomuch for my likeing.The truck has the stock(rotated)oin back in it now and I prefer the stock pin.



In Hind site I would have left the bottom alone,and would have come up about 1/4" then started my steeper ramp.It just fuels to much to quick and smokes like a bastard when gettin the load going.Soon as im up to speed and spooling it made great power and smoke was fine...to much fuel to fast on the bottom end IMHO.

Yep, a ground stock pin allows full fueling. But, an aftermarket pin is a bigger diameter at the base which helps with lost boost fueling.
