mods I can do to my renix 4.0 before it becomes a stroke
Last night I felt how little power my 4'0 has. I was buried in mud and even in 4lo with 5.13 gears I couldn't spin my 38 in boggers like literally my motor would my rev past 2000rpm.
I plan on making a 4.6 stroker but before then I want to know what mod I can do to add power but I can still use on the stroker.

When I installed mine I noticed a difference, smoother idle and revs. Slightly better mpg, with a bored TB. The multiple holes in the injectors have a better spray and help atomize the fuel.

save your money for the 4.7L. spend the money in the right place and you will be blown away by the difference. 24lb injectors, 9.5 static compression ratio and a cold air intake and straight exhaust, with the 99 intake and a massaged ~96 head, ditch the EGR and you'll have all the power you want.

Look at your exhaust headpipe near where it bolts on to the exhaust manifold. see that big "crush" in it that looks like it was put there to clear the front driveshaft? Eliminate that crush.

Check your acclerator cable and be sure you're getting full throttle.
