Lack luster performance?
Posted: December 9th, 2021, 1:51 pm
Hey group, finally got the stoker into the jeep. Broke it in with rotella and I am continuing to use that oil to keep the cam alive.
Jeep starts up and runs great. although i do hear an intermittant miss at idle but I'm going to blame that on the cam for now.
I feel like this thing just doesnt have the power I was anticipating...Or maybe I was expecting too much?
I would love for some experts to critique my set up and maybe point me in a direction I may have failed to address.
1994 wrangler, ax15, 4.11 gear ratio, 37 inch tires
block was bored .030, cleaned, cam bearings installed, etc. No deck work.
Russ Pottenger ported head with chevy ls valves and springs, 58cc chamber
Russ forged pistons with 24cc relief with matching floating scat rods
scat stroker crank
comp cams 68-235-4 cam and matching lifters installed dot to dot (straight up)
felpro mls head gasket If I remember the compressed should be .043
late model, horseshoe style intake that has been port matched to Russ's intake ports
Ford blue top 24 lb. injectors, fuel pressure is at 40 psi at idle
bbk 62 mm throttle body
restrictor removed from factory airbox lid, k&n filter installed
bbk ceramic coated header
2.5inch exhaust with bbk performance muffler
crank sensor has been indexed to provide 2 degreees extra advance
distributor sync has been reverified and is right on the money.
electric fan conversion.
I have about 150 miles or so on the engine now, have changed the oil twice.
temps stay right at 210
The jeep runs and drives fine, and yes i do feel a slight increase in torque when i really step on it. I guess I feel like I was expecting a much bigger increase in output from my investment. I'm a long time mechanic and have had my share of hot rods and engine builds but I guess the seat of my pants just doesnt feel where my money went lol.
I would any and all feedback or questions. I feel like I'm missing something.
