351W Redline

[Brown_Muscle]

Ok I tried searching for this but nothing seems to come up, this has just been bothering me haha. I have an aftermarket Tach which you can set the redline to, however i have on clue as to what the redline is on my 351 Windsor. I know at WOT it shifts around 4000-5000 RPM. Does anyone know what the real redline for my engine is? Thanks

There is no redline on a stock Panther 351. If you just floored it in neutral it would rev until your valves started to float. You're between 4-5k? That shifts pretty high. My 351 stock was never over 3500 RPM unless I held a gear. The car didn't make any power over that point stock anyhow. Due to the 351 having oversize main bearings, and non-forged internals, it is said to keep it under 6000 RPM. I have my HI-6 set at 5500 RPM. You can see my tach, with the redline indicator set to 5k, here:

Oh wow I did not know that, thanks for all the info, and I thought my car shifted in a low RPM! Ok then I guess I'll set my marker to around 5K then, I did have it at 6.

It should hold 7 or so. My bronco is factory set at 5500.

With that VV if it spins to 5,000 you're doing something. Won't make power that high anyway. Tiny carb and terrible intake just won't let it breathe.

Wow...that wasn't WOT, was it?

Yeah I know, but Ill keep my VV anyway cause I'm putting my car in some shows so I'm trying to keep it as original as possible, however if I somehow find a really cheap 4 barrel+intake getup i may be tempted.

According to the vid description:

Light accel from tollway to 65 MPH.

Uh oh, was it horribly slow to you?

That was just (most mangs) normal acceleration. No secondary action and it went from 2nd to 4th in a heartbeat. There was construction on the tollway and we went from 5 lanes to 1 within a few hundred feet. There were also metal plates on the highway, which you can hear me slam into toward the end of the vid. My buddy Michael
also made a weird alien like sound as the window was rolling up. Creepy. Did you hear that, too?

The car WOT with the windows down is a different animal. We filmed the "Lower Wacker Drive" vid the same night, LOL. In the vid, from 5 MPH to about 60MPH only took about 7 seconds. It would still pull hard on a stock box even at part throttle, I would assume. If you have not seen the POS immortalized on video, go here:



The car seems to gather speed in a hurry without drama (on the inside, at least) unfortunately. It makes for a boring drive. Hopefully 1987cp and LtdMasta can confirm this. Too bad Epi didn't have a video camera when we cruised Chicago.

Unfortunately, the car is too damn slow. After I find some good heads, it's time for round 2. Someone on this board has actually held the cam for it :smirk:.

HAHA i love that video! I thought you were flooring it coming up to that white car and then when you REALLY hit the gas I was like oh shit. Yeah thats my story

I think the guy in the white car was trying to get away from us, LOL. He was hauling ass compared to what everyone else was doing. I had to gun it to pass him. How I've never been arrested driving that thing, I'll never know. I need some sort of push bar like yours. Too bad you're not local, as it would be fun to cruise together. How many miles do you have on your car? The paint and chrome look fantastic.

[Brown_Muscle]

Thanks yeah that would be intense, its got around 111K currently, thats about 1000 miles ive put on it since i got it in september, and thats including the 200 mile drive from maryland to NJ! How many miles you got on yours? The only problem is my front bumper it has some rust on the top...I like the push bumper but i probobly wouldn't have put it on if my front bumper was perfect...opps were getting a little off topic in this thread.

Back on topic, when you get a vid of the exhaust, also do an in-car one of the engine at 5k+ winding out. My car stock didn't sound too healthy at that speed.

No, no, not that...just between this comment:

My 351 stock was never over 3500 RPM unless I held a gear.

...and the fact that in the video it only got to about 3 grand or 3500...I wasn't sure.

Ok sure thing, I really rarely floor it in that car but I doubt it'll get to 5K or more haha more like 4K to 4500, but ill give it a shot it may be a while though (I only drive the car on the weekends, I don't really need it during the week)

Oh I see. That vid was from this past summer, and the car hasn't been stock since 1998. If I were to gun it in the video you would see a shift around 5k. With the TV cable adjusted to spec, it wants to shift around 6k, but the rev limiter is set to 5.5k and the motor is on it's face after 4k anyway :nonono:.
