    Modified Holley 701R-48B, need some help with fitting sizes. (Looks almost identical to 300-64)

    I have this intake I found for really cheap, so I want to use it. My stock intake has significant damage to the threads on the 1/2" NPT threads that were used for the heater core. I have already modified the middle 4 holes on the intake to fit the newer style TBI heads. I need to know what sizes...

    Mechanic says transmission won't go into park or neutral

    Long story short I've been working on my old 1993 1500 2wd but ran out of time and issues were over my head.

    After owning this truck for 7 years and replacing 4 FPR's I really got tired of working on it. The last AC Delco only lasted a few weeks.

    Hello! I’m new to the forum. I haven’t found exactly an answer to my question so I figured I’d post here. I have a 99 2 door Tahoe that I’m LS swapping. I am using the x max so it’s plug and play with the motor and Trans. But I’m trying to figure out if I need to keep the stock ecu for my...

    93 3500 Regular Cab - 502/Accel-Ram Swap

    DISCLAIMER: I've previously stated the truck came with a 502 Ram-Jet. This was a newbie mistake of me and it's an Accel DFI not a Ram-Jet. Note however that this Accel is also called/labeled "RAM" which is what caused the confusion to begin with. So to begin my build thread I'd like to clarify...
