    L29 timing gear

    Does anyone run an adjustable timing set with the stock crank sensor and timing cover? I've read a lot of threads were guys had one and when putting the cover back on it won't spin. I know a double roller is out. I'm sure anything from rock auto would fit, but no adjustable sets I've seen...

    2000 L29 454 Build

    This is my first post here. The Truck this motor will be going into is my 1998 Chevy K3500 Crew Cab Dually with 140k miles. The 454 that's in it is full of sludge and the oil and oil filter always has metal flakes in it. I've been driving it like this for 7 years, the metal in the oil is...

I've seen sets on Summit and Jegs that say they are direct fit for my truck, but then they say they are only for up to '95. If anybody has any ideas, maybe a part number, that would be awseome. Thanks...

    l29 heads

    has anyone used these heads on their 7.4l vortech? I am preparing for the worst if I pull my heads to fit a coolant usage issue and one of them is cracked. I do not want to change intakes or fuel systems. Stock set-up 1997 K3500 cclbdw Maybe someday I will do the GM Performance HO cam...

    Gibson GP113S-C

    It seems like Gibson is the about the only one who makes headers for the l29. Are people happy with them? Is fitment good in a K-Series? Longevity? Plug wire issues? I need to put mufflers on when it comes out of storage. Wanting a 411 swap. Probably head gaskets due to it using...
