Subject: My new engine

Ok so I have around 100 miles on my compleate new engine. I was hoping for a huge perfomance increase but I am trying to keep below 4000 RPM, so it is a little hard to gauge it. I still get a little "twitch" around 35-3700 RPM right before I shift, like it is missing slightly. It has a 284 re-grind cam, 32-36 webber & I also got a new 002 mech dizzy to replace the old shitty vacuum advance. I have to say it is nice to not see any oil, smoke, leaks, and have a spotless engine bay without the smog stuff.

How many miles should I drive before I really open it up? I only put around 250-350 miles a month on it over the last 5 years.

Your not going to get a "big" improvement over stock with that setup. However, you need to address that miss or skip. Sounds like fuel since it's intermitent. Well..... could be ignition. I usually start ripping on my motors around 1000K and after one oil change at 500. John _________________ "Chicken make no good house pet!" "Less brake, more accelerator" #1665778

Why not go on a road trip to put some miles on it? Could be fuel related or evening timing check them out and do what the car was made for...... Driving! i second the oil change at 500. _________________ frank o 1971 2002 sunroof, daily driver, Recaro SE, Turbines, 5 speed

If you road trip it for break in reasons - STAY off the interstates. Varied rpms and engine loads are better for break-in of the rings. Prolonged highway drives will tend to glaze the cylinder walls during this period. Some folks encourage lots of "engine braking" (down shifting and letting the motor slow the car) , while others recommend against it. Personally - I find brake pads to be far cheaper than driveline parts, so I rarely engine brake.

or....you can do what I did w. the Stroker....bolt on an aluminum flywheel and zing it to 7800 rpm within the first 15 minutes of driving... then melt down your SuperBlue brake fluid on the way back to the shop! This was 2 years ago, and maybe 3500 miles or so, later - the motor still seems happy as a clam!

(if I can't set a good example - the least I can do, is serve as a horrible warning - right?)
