I see in your signature you have 42lb injectors. Did you use the 42lb marine injectors? Do you have a part number for them? I'm glad I asked because I wasn't sure about having to change the injectors. Thanks.

The stock injectors are set to 24#'s of flow in the stock tune. I don't know the part numbers, but the 8.1 liter marine injectors show up on ebay from time to time. Just don't get the truck 8.1 liter injectors as those are NOT 42# rated, much smaller... Quote Link to comment Share on other sites More sharing options...

Thanks. as steated above the stock injecotrs are 24#ers and 42lbs are marine injectors that can be used for your cam swap upgrade, racetronicx.com sell them Quote Link to comment Share on other sites More sharing options...

Do you have a direct link??? All I see are other 42's with the wrong connector (would still work with an adapter or new connector).

Where do the 44#ers come from? Is that what I need & not the 42#ers?? I can get the 8.1 liter marine injectors easy. I'm in the marine service business & a dealer for Indmar marine engines who marineize the 8.1 big block. Thanks. Quote Link to comment Share on other sites More sharing options...

Thanks. well the OE 8.1L marine injectors are so called 42#ers but in actual specs they are 43.5#s or real close to that, so yes the OE 42#ers for the 8.1L is what you want Quote Link to comment Share on other sites More sharing options...
