292 chevy I6

I am building a 350hp Chevy 292 I6 for a 1949 Chevy 3/4 ton Pickup, what is a good rear end and transmission for it~ It will be a daily driver but I want to be able to get up and go when needed. I want a 4 or 5 speed manual that is pretty easy to find, well built and budget orientated...

The torque will be high so a high geared rear end is wanted.

How would a 5 speed tranny from a 2.2L S-10 work? Will it hold up? Is it geared right?

The 2.2 5-speed will be quite a bit on the weak side for the torque rating of the 292 even in stock form, I would look more for something newer possibly an NVG-3500 if were MY choice.

Being that the 292 will bolt to any tranny that fits a 350 SBC you have MANY options. I just got done researching 4-5 spd manual trannys for my 52 chevy p/u and I'm going to begin looking for either a muncie or saginaw since they are fairly common in junk yards. NV3500 and 4500 are also a good choice.

http://www.motivegear.com/tech_info/...nny_guide.html

The rear ends you want to look for are found in 67-69 camaros, 68-78 novas, and 64-67 chevelles. These rear ends are great because all you need is a conversion kit for the 3" rear end. Relocate the perches and spring mounts and you're golden. These rear ends are very close to the stock width of the AD series p/u rear ends hub to hub (roughly 60") and you can drive them faster than 50mph. The only other thing you'll have to do is custom cut/weld a drive shaft which you can either do your self or have done for about $150-$200.

BTW grats to you for finding a 292 I6. I originally wanted one for my 52 but couldn't find one. I am now searching for a 350 or 400.

What about a saginaw or the tranny that came with the 292, they're both 4 speeds? What rear end ratio should I use? I have a 10 bolt gm rear out of a mid 90's s10 with the 4.3L v6

Do a search for rear end ratios and you'll find a lot of good information from past posts. With that kind of rear end you can find a WIDE range of gear ratios. You'll want to pick one depending on your application (i.e. street, track etc...)

Rear ends is where I come short, You could give me a pile of parts and I could make an engine out of them, but give me a differential and I'll look at you like you're stupid
I will be running around 300HP and 350 ft. lbs. for the street and the occasional race with the s-10 guy(see my other threads...) I will be mostly in the city... with a few 350 mile trips to Anchorage yearly.

Most of the time a 3.42 is a good gear without overdrive. You don't want to go much more than that with a 4 speed. With overdrive you could go to a 3.73 pretty easy. Tire size will also make a difference. If you go up to a 3.08 you will be putting a load on the clutch when you take off. The S10 rear end might be the 7.5. Somewhere in the '90s they started using the 8.5 in some S trucks with the 4.3, so you need to find out what you have. I don't recommend the 7.5 rear end. The 2 wheel drive and 4X4 rear ends are not the same width, so you also need to find out which one you have. The '70s F body 8.5 rear ends are a good swap and are not as hard to find as the narrower Nova 8.5. There is only 1 inch difference in them, but the Nova rear end is a direct bolt in for the first gen Camaro, and a very popular swap, so they are harder to find.

The rear end is from a 1994 4WD s10 with the 4.3L Vortec backed by an automatic tranny...
It is 50" from lug bolt to lug bolt

292 recipe

Just wondering how you're getting 350HP out of your 292? I finally found a 292 for sale about an hour from me and the guy said I can come pick it up for $50. I am waiting for casting #s right now but will hopefully to pick it up this weekend. I've been researching the 292s all day today and have found many (expensive) performance options but was wondering what you've done. I'm assuming you've done the lump port upgrade... Thank you.

-Greg

I am in the process of building it, but here's what I'm doing:
Holley 500 2bbl, Clifford intake, lump ports, 1.90 int. and 1.55 exh. valves, Fenton headers, a TO4B turbo, 3 inch exhaust, and lots of shiny things

It is still in the process, so some things may change...

Maybe this will help. I am going to begin looking for a muncie .................................................. ...... or a saginaw because they (saginaws) are pretty common in junk yards. I didn't mean it to sound like muncies are common in junk yards too, all though they can be found. I found an M20 in a local yard called NoDak Klassics. Being that this is a budget build though, I am going to try to find a saginaw for my build.

BTW thank you for the info on the 292 build. I hope to pick mine up this weekend.
