    Whats the typical rev redline for a late 70's to early 80's 350? The engine is not the orginal engine, but its pretty much a stock motor internally with edelbrock carb and intake with headers to boot. I'm pretty sure pistons, heads, etc are stockish.

    Trying to set the redline on my tach.

    Thanks!

    I wouldn't want to try and send my 350 past 5500. I have had mine in the mid 4K's and really didn't want to push it past that much. It really starts to run out of power above 4500 rpm or so. At least mine does, and it is the 300 hp Chevy crate motor. I don't see the need or desire to push them much past 4500 RPM unless you really need wheel spin in the mud or sand.

    Ahh good. I [censored] before then and don't ever run that high on the freeway. Some times when I'm gettin on it, it seems to be screaming and loosing power (about 4500) and I wasn't sure if that was bad for engine or not. I feel better now. Thanks!

    5500 is safe for stock engine. If your loosing power at 4500 it's probably the HEI dropping off. You can put a hotter coil and module in it and get your power back and then some.

    I have full MSD ignition with no module (so no dropoff) and my power still dies above 4500RPM, so you are not missing anything.
