how hard do you rev your stock TBI 350? i run up to 5200 some times, average not more than 4
I have reved my carb 350 up to about 4500-5000 tops. It doesn't have any power above that so there is no reason to rev it that hard for me. I don't know exact RPM as I didn't have my tach in then, but since the tach I have been above 4500 a couple of times.
i like to stay under 4500 /forums/images/graemlins/shocked.gif
My GMPP stroker motor redlines @ 5,200. Never had the need to go over 4,500 yet. And anyway, I love all the low-end torque...........................

I pushed my 415 right up to the 5500 redline just the other day in the mud... it really sounds sweet right there.. but a little on the hairy side of a stroker at the same time. I usually keep it under 4600 on a cast rotating assembly.
4k is about where the 75 shifts if I stay in it. the 79 I can get 5k out of with the crate. my Supra......Pulls real good all the way up to about 6200 Redline is 6500 /forums/images/graemlins/thumb.gif
My 86 RX7....10,000 rpm or so shifts. Once they are warm they pull hard up to 10K. Just have to be warm our they spit out apex seals.
I take my 95 up to 5000+(tach stops there)pretty much on a daily basis (offroading at work).
most 350s i have seen will rev up to 5500, dont know what red line is at but they shure dont make any power beyond 5000. In my luv though, once warm that little 1.8L isuzu will rev up to 6000 no problem. But then again its power band is at 4800rpm /forums/images/graemlins/tongue.gif
Don't have a TBI 350, but I do have a carb'd 402 BB with Full Roller rockers, a balanced crank, Forged psitons, and a Crane Cam....I do 5000 or so RPM's max...2 chamber flow masters with no tail pipes at 5000 RPM's is LOUD! /forums/images/graemlins/ears.gif /forums/images/graemlins/thumb.gif
My shift lite is set at 6000, but Ill take it to 7 if need be.
I have gone at tight as 7800. /forums/images/graemlins/eek.gif I almost crapped myself when I hit the recall on the tach! I even took a pic of it. /forums/images/graemlins/rotfl.gif
I've gotten my carbed 355 up to 6500 once, I let off when the tranny started making noise. I usually try not to take it above 5k too much though.
Highest Ive hit is 5000 cause i was dazed and forgot to shift untill i realized my engine was roaring lol. In mud pits most ive hit is 4500. My light is set at 4000 I usually shift around 3000-3500 driving on the street
My K5's 355 has seen 6,000 rpms on occasion usually not much more than 5,000 though.
My camaro's 469 goes to 7,000 every time i take it for a drive. /forums/images/graemlins/eek.gif
ive hit 5500 -6000 quite often when mudding and in dunes, but when cruising on trails, i dont go higher than 4-4500
Mine always shifts at about 4,200...no need to go higher, I've already reached my power peaks.
Mud racing, I take my 454 to around 6000 or so. One time in my old Chevelle with a hot 350, I had it at 6800 in drive with 2.73 rear gears. the front end started lifting up. /forums/images/graemlins/grin.gif
That's shifting too early for a small block. For maximum acceleration you want to shift at a high enough RPM that the RPM after the shift will be very near the torque peak of the engine. Somewhere closer to at least 4,700 RPM is where a stock small block should be upshifting at full throttle with an auto tranny. /forums/images/graemlins/cool.gif With a mild cam the proper shift range can move up into the 5,000-5,500 RPM range.
You need a pretty hot cam and some serious valve springs to make it up to the 7,000 RPM range that PI likes to play in. /forums/images/graemlins/shocked.gif A good balance job is also in order when revving 'em up that high. /forums/images/graemlins/cool.gif
I shift my 377 at 7200 and have the rev limiter set at 7400 It's hit 8200 before I got my rev limiter (drive line faiure)My big block gets shifted at 7000 rev limter set at 7200 /forums/images/graemlins/truck.gif
Both of those engines have had a few "upgrades". /forums/images/graemlins/wink.gif
i run my stock motor to 5200, the "PROJECT VETTE" gets cranked to 8100 when were playing. my old Z-28 with an LT-1 used to get shifted at 6200. and yeah i had an RX-7 and it was a beater, so every shift was 10,000 + or bust, and let me tell you 10 thousand RPM shifts will break a tire or two loose. /forums/images/graemlins/thumb.gif
