View Full Version : The Red Sled vs. 1978 454 3/4 Ton Chevy
chevyorange 02-18-2009, 08:41 PM Well, the time had to come. At age 35, my 6 year junior brother finally has a faster car than me.
I'm half proud, half disappointed.... I have a 2.4L/Auto HHR, he was in his 3/4-ton Chevy with a 454, TH400, and dual exhaust.
I spotted him ahead of me in traffic by chance on a clear night, at dusk... and we rolled up to the next light.... he was honorable and asked if I wanted to "go" and I said sure.
The light began to go red the opposite direction so I loaded up the transmission a bit and when it was green we both hole shotted it perfectly. I hung with him for exactly 3 seconds.... and the big, black 454 left me behind.
I did have an excuse in my pocket - traction control was still on - and it was a short race, maybe 400 feet... but we both burned rubber on the launch so I'm not sure TC would have made a difference.
His other car is a 1994 Buick Roadmaster with the Corvette LT1 and I know that is faster than his truck so I won't even bother.
Never have I wished I had bought the SS more..... :)

That makes my HHR a link in the chain of the anchor. That thing got UP.
Yonash 02-20-2009, 12:23 AM 454s are actually quite potent. stock they might not have a ton of hp, but they're torque monsters, and if you start modding it, you're in for some real fun.
chevyorange 02-20-2009, 12:26 AM Yeah, in 1974 my brother's 454 was probably mostly suitable for towing and hauling, but its been gone through... and with a 4.11:1 rear end and the tall 1st gear of the TH400 transmission... and yes, its heavy.. but it flies! Endless torque.
Yonash 02-20-2009, 12:45 PM you want a real crazy 1st gear? have a look at 700R4 ratios compared to a TH-350 or TH400
chevyorange 02-20-2009, 01:29 PM Well, I hope my brother doesn't swap one of those in behind his 7.4L engine... it would be hopeless!
Yonash 02-20-2009, 04:09 PM lol i wouldn't put a stock one behind a 454 either haha, that'd be transmission suicide. there are a few companies that make some pretty tough ones though, check Pro-Built Automatics and Bowtie Overdrives, both have some stout ones. i read this somewhere, and don't remember EXACT ratios it talked about, but the 1st ratio in a 700R4 is so tall you can run a 3.23 rear and it'd be like running a TH350 with 3.92 rear or a TH400 with like 3.88 rear. a 3.56 rear with a 700R4 is like a TH350 with something like a 4.22 rear! but then you have an overdrive 4th gear to go nice and happy with your 3.23 or 3.56 rear, making for decent economy and nice low cruising RPMs. i believe one of those sites even has a stout trans called something like a 700L60 or something random like that, that is a improvements of the 4L60E transmission, in a 700R4 case, so you have a better trans, mean gearing, and no need for a computer!
chevyorange 02-21-2009, 08:08 PM Younash: A true gearhead! I love it.
My blood runs Chevy Orange but you're just ON IT!!

Man I remember my 700r4 with a 4:11 rear end in my 78 Malibu, I could pull the front tires off the ground bout an inch, 1st gear in those trannys are potent as hell, i always called it the coffee spiller gear. Second gear wasn't bad in those either but after that there wasn't as much BAM left.
chevyorange 02-21-2009, 08:14 PM Yeah, pretty much when you match it to a 4:11 rear end.... hell, even without a 454 it would be a good hole-shot machine. Add the crazy torque in even on a mild 454... its just fun.
saxrocks2009 02-24-2010, 12:39 PM Yea my first truck was a stock 98 chevy 1 ton with the 454.. It was very good of the line but would lose its self a few hundred feet down the road.

Your younger brother is just lucky it wasn't me in the other lane..I'd of showed him something with my 2.4......:cool:
I'd have showed him how good mine corners making the first turn away from him...:lol:
Goose2448 10-06-2010, 12:47 AM My HHR 2.4 auto will beat my truck in quickness up till about 50 or so, but after that its all Small Block power.
C20
350 vin M
With the few mod to it, est 400 HP and around 500 ft-toqure
4.10 rear
THM-350 trans
5000 pounds with me in it
The truck is still pretty quick out of the hole, the HHR may get half a length on it, but thats it.

Yep, had a 91, it was slow as mud at the track, sounded great, could peel out np, but slower than a Prius! lol
c2vette 10-06-2010, 09:44 PM I would have had to put my 454 in 4wd. If it is any consolation he probably burned about 5times as much fuel as you did.
