Not sure I would have even touched that axle but its fun to watch and see the improvements. Full second off the 0-60 for around $600 is no joke.

[@andybowyer3602]

The smirk on your kipper when you let rip on that new diff!! Comical to say the least 🤣🤣🤣 👊✊💥💨💨💨

[@da_jeezuss8922]

Jack showing a lot of restraint not going super ignorant with the gearing. If I had an El Camino, I could not do the same 😂

[@wayne7399]

Thanks for the vid. It’s been hard finding a demo/reaction of 3.73 gears. Nice ride btw

[@aceofhz8807]

Smooth transition at 7:20. Love how you modify and improve pretty much anything that moves on this channel, makes me want to get out there and work on things. Keep it up, Jack!

[@JackCecil]

Get it done!!

Sweet! Good stuff Jack. The SS is a beaut!!

Can I get the part numbers. And total price of package. I would like to buy this upgrade

Just pick up a set of 3.73 for my 65 impala ss powered by a nitrous breathing sbc 427. Troy at QP is super cool guy, can’t wait to drop the gears in.

How did the install go? I have a 65 impala that needs some 3.73s!

[@rudog62]

If you're thinking about changing mufflers, I highly recommend flowmaster 40 series. Those are the og in the muscle gang and sound amazing. Iconic sound. Super 40s and super 44 don't sound as good.

long time viewer here ole Jacky boy. the RC content was cool and all but if there was a different channel that had uploaded something else at the same time I would probably click their video first... just my personal opinion is all I mean no offence by it.. but with this elco content you have certainly popped up a few notches on the old list of content I watch while on break at work takin a poop and after work before bed.. keep up the good work!

[@kylebaker652]

I was getting real tim the tool man vibes when you were driving the elco and you got excited

[@peachdaddy]

I've used qp parts before and can say for the price it's not bad at all. Almost always cheaper than everyone else. Haven't had any issues so far.

[@ZibrayMusic]

Yaaaaay another video. I'll let you know what I think shortly haha I loved the video. Keep up the great content. 👍

[@cfmechanic]

Cool. I went from 2.73 to 3.42 was big change recently took out 3.42 broke pinion and had 3.73 installed. Very happy and with 275/60r15 I think 70 shouldn't be bad

Crazy! No whine, no issues! Worked perfectly for years and now the next owner is enjoying it too!

Does Marcus not work at HP anymore? I can’t recall seeing him in any recent videos

Didn’t check gear pattern with bluing or backlash with dial indicator? Kinda just went for it there. Sounds ok on video. 🤷🏻‍♂️

@@CannondaleF700 Don’t get all excited.

[@JackCecil]

It’s very quiet. No issues. I understand the physics and know from RC cars how to set backlash.

[@Ragnarx]

Would 3.9* or even 4.10 gears be too much Rpm for that motor on the street? Looking good

[@JackCecil]

Yea that’s too steep if you ask me

[@Ragnarx]

@@JackCecil Would it technically get you to 60 a lot quicker though? At the cost of top speed

Feel free to throw your unwanted parts this way! I got a 79' Elco.

[@8004dodgers]

Do you have the 200-4R in here? Reason I ask because I didn't see OD on the shifter indicator but the pan looks like 200-4R. G-bodies for life 💯

just asking what about highway speed? what rpm at 60mph

Are your rpms higher or lower now?

[@robertpierce1981]

Never seen anybody assemble a large domestic axle and not use some kind of dark colored lube to do a pattern test check on the gear set.

Jack pls dont use drag radials on that 7.5 10 bolt. Slicks are much more forgiving. Unless you go the M/T E.T. streets route and not the E.T. street radials

Be careful of the trans on decell. The transmission bell housing will not be happy.

[@JackCecil]

Why not?

[@TheKevin1183]

@@JackCecil th350 tend to shatter the bell housing when you decelerate from higher speeds with 3.73s. Ive seen 700r4 do it as well. Usually its in the same application as what you have. I know you are talking changing it out but just a little something to think about.

[@TheKevin1183]

The 700r4 are more common with more aggressive gear ratios. 3.73 is more of a th350 issue

[@sbcdime1]

Strange that ive never heard of this. Personally i have only broken flexplates under those conditions

Bro, 373 gears are straight highway gears. Not race gears. At 70 mph you should be running around 2000 rpms.

[@musclebone7875]

Depends on the kind of transmission that you use.

[@salimsopari]

Depends how many gears you have, 3 or 4

[@Antonio-nc2be]

With overdrive is fine but my nova with 3.42s and c10 with 3.73s and 3 speed transmissions are screaming 😱 on the highway. Not as bad as my 9 second camaro with 4.56s. I haven't decided what gear to run in my 77 elco I just bought

[@eduardonunez4377]

I just did this swap… If you want to go fast for the first few seconds it’s well worth it… but that’s all you pretty much can do. You can’t use it on the high way and you look like an idiot going 55 at 3k rpm. If you have a 8.2 rear end with a 2.73 rear end LEAVE IT as is. I promise you will miss the ability to cruise at 90 at 2200rpm. If your definitive on getting a posi then nothing higher than a 3.08. This gear swap gets old real fast especially with your mpg. You’ll litteraly see your needle move as you drive.

[@raymondwilliams7732]

Yes your right, don't it

[@salimsopari]

For that reason im swapping th350 for 200r4. Ditching the 3.08 for either 3.55 or 3.73

[@Antonio-nc2be]

Totally agree 👍 my last 3 hot rods were 4.56s 3.73s and 3.42s all with 3 speed transmission driving 50-65 at 3k RPMs on the highway gets old real quick. Might just keep my 2.73s in my elco
