Default denny t?

ok i have decided for the first mods to my truck im gonna get the spring and fuel pin setup(and gauges of course)

my question is,should i get the 3200 rpm spring or the 366 one?and what are the benefits of each.

also,which fuel pin do you guys run/suggest?i almost have my mind set on a denny t but i have heard some about the m&h ones so i was just wondering what all of yall think.

ive heard good things about denny t and m&h pins. basically the same things m&h just has more choices of pins. im running the m-5 pin and it deffinetly makes a difference.

The 366 spring is the 3200 RPM spring. You can get springs that allow more RPM but I wouldn't recommend it as the VE doesn't make much power at high RPM anyways.

I've got a DennyT Stage II fuel cone and love it. The M&H cones have more options for the fuel cone ramp, but the DennyT Stage II and M&H 5 cone are pretty much identical.

Not trying to be rube I think you mean fuel pin? But also with higher RPM springs you need #60 valve springs or they will start to float at about 3600RPM's.

I think it's 3600 people with 3200rpm springs don't do them. Mine will hit 3100 n not float them. Though it has no power that high.

The DennyT or M&H part people are buying is actually the cone. The fuel pin rides on the ramp of the cone, so I'm not really sure how the cones became known as pins.
