So.... the engine will not rev easily to 5,000 RPMs at wide open throttle in 1st and 2nd gears?
Did you follow 22REP's recommended break-in procedure?
"INITIAL START UP:
When you (or your shop) are going to fire up your engine for the first time......
Since I’m sure you (OR YOUR SHOP) have set the distributor to the general area of #1 TDC (watch the video here), it’s time to crank it over.
TEST THE THROTTLE POSITION SENSOR!!! Your timing depends on a properly functioning / correctly set TPS!!!
Roger over at 4crawler.com has the most detailed and easy to follow procedure for testing and adjusting your TPS.
Click here and follow his testing and set-up procedure. Don’t rely on the fact “it was running fine before”. A few minutes testing and adjusting it now will save you frustrating hours trying to tune / time your engine."
Have you checked that the throttle body and throttle linkage is opening all the way?
You need to check the TPS and ignition timing.
I don't believe it's a mechanical issue with the long block.
Shifting at RPMs is just a personal choice. I tach my engines up to 4500 to 5,000 in 1st gear almost every day, at least once.
My casual shifting is at about 3000 to 3500 RPMs. I don't putt around.
On a 22RE..... LCE's 2.25" Cat Back exhaust with their header *may* cause a loss of torque in the lower RPMs, but you should see more power after 4,000 RPMs.... according to the general opinions of the some "experts".
The difference in power from a 22RE stock to 22REP's Stage 2 is significant! .... about 19 more HP and 13 ft. lbs of torque at the rear wheels.... VERY noticeable!
I am curious what Jim at 22REP would say about the LCE header and cat back exhaust on his Stage 2.5?
Gnarls.
