Build questions - Groundhog Resurrection continues...
« on: September 20, 2017, 08:19:04 PM »
Okay, it's time to open up that can of worms where I ask for recommendations!! LOL

I just got the 4.0 back from the engine builder and figured I'd run these items by this trusted crew.

So... what are the recommendations for:

Fuel injectors - I'm most likely sticking with 19 pound injectors, but there are many forum chats about different types of injectors - or should I just go OEM?
Distributor - Looking for  pretty much stock, but is there a preferred brand or type you all gravitate to?
Exhaust manifold gasket - 

Keep in mind this is only a mild build - mild Comp Cam, Melling HV oil pump and Moroso 7.25 qt.off-road oil pan, Melling timing set. There will be no cold air kit or fancy exhaust sizes - I've learned my lesson there. LOL

Nice Job!

Back in 2004 when I did my 4.0 swap in my YJ I went with Ford Mustang 5.0L Bosch 4 hole 24 pound injectors with a Borla header and cold air intake (plus a Mopar Performance ECU)  because of the ECU I needed to use 91 octane...   Those injectors plus the intake and header made great power like a dirt bike getting "on the pipe" at around 2500 RPM!  It would smoke 33's in 2nd gear  :mrgreen:

If you don't want as big of injectors, dodge neon injectors are 19 lbs but 4 hole like the fords. With a mostly stick engine, you probably don't need more than the stock injectors. The better atomization of the 4 hole injectors will smooth out the idle though.
