Re: New to me 78 burb

You could go with an auxiliary gear box. I mean 2 sticks are better then 1 right? Advance Adapters sells the Ranger Torque Splitter. It's a .73 overdrive where a gearvendors is a .78. I put some numbers into the rpm chart and here is what I got.

Re: New to me 78 burb

I was at frog follies last weekend and i did see one of those a866 trannies for sale it was a good price so i'm really thinking about calling him up and buying it in the next couple weeks. The guy had it in his hotrod and changed out to an automatic. the only thing i have been reading is that the stick will not be in the same hole so i would have to cut another hole in the hump and cut a hole in my carpet. I really don't like doing that if i don't have too. that's the cheapest overdrive i can think of. I think it's a .73 overdrive too.

Re: New to me 78 burb

A 78 should still have a bolt in trans cover so you could always find a new one to cut up. You would still have to cut the carpet either way. The NV4500 is always an option. If you look around you can find one cheap. It too is a 0.73 overdrive. I do think heavy towing will suffer with an a833. It may work for your needs, so on your current trans try towing with out using first. The a833 has a 3.09 first gear the sm465 has a 3.58 second gear. So it should give you some idea, but a sm465 second gear is still 0.49 lower. If your look for more here is a good thread on it. "What can be said about the 4-speed New Process NV833 overdrive manual transmission?" Also down below is that same chart with the a833 ratios plugged in.

Re: New to me 78 burb

I see your point regardless i'm going to have to cut the trans cover and carpet and if i don't want to cut the floor i would have to go gear vendor. i'll do some more research and see which route i want to go. thanks for the charts.

Re: New to me 78 burb

I'm wanting to buy a headliner for my burb but every place i have been looking only offers the one with the rear cut out. i think it would make more since if they made one that didn't have the cut out and the you just cut on the dotted line if you have rear air. mine is a scottsdale and only came with front air.

i'm also thinking about buying the sniper efi soon i know a few people that work there and i live in the town that makes them so i think i will try it out. we will see how that works and then go from there and get the gear vendor later because i love using low gear with a trailer getting gravel and mulch and live to have overdrive. i hope next year to do a vortec 350 swap to get that extra hp for towing my vw's to shows. The true test is go over Mont Eagle to a couple shows.

Seems they only make the rear a/c option headliners. Mine is falling just the vinyl the backer is still good so I bought the vinyl and just going to replace that .

Re: New to me 78 burb

Very nice burb! I've thought about an over drive on my 71 BB truck, but quite frankly I can buy a lot of gas for the cost of the gear vendors. If I did add an over drive it would be gear vendors.

Re: New to me 78 burb

Ok I have been thinking about doing a top end for my truck over xmas break. I believe the old 350 only has like 180 hp and i'm wanting to be able to just get around 300hp. A new ls motors are just a little over that so and my old 2011 truck did great towing my vw to shows no problem even up mont eagle it did fine so I just want to get that out of my 350. Me and a friend at work get a week off and we thought about pulling the motor to freshen everything up and clean and put a new Throwout bearing and clutch. It smokes at start up so i know the valve seals need to be replace but why spend money on those heads. I think i want to lean towards a vortec style aluminum head does anyone have any suggestions. While it's out I have been reading that the summit 1100 cam is great for towing. I just need to figure out what heads are good for that type of application. i read somewhere that i would be spending most of my time in the 2500 to 3500 rpm range anyways. While i'm doing this upgrade i'm going to go with the sniper efi with the whole kit with the dizzy and the spark box. My burb also has 3.73 and plan on a gear vendor down the road to hit those gears between gears with my sm465. Let me know on the heads.

Re: New to me 78 burb

btw i have had a cracked windshield since i've owned it so i turned it in on my insurance and they came out last week and put it in for me looks so nice. i wasn't there to help him and he didn't put the seam in the middle of the windshield and that bugs me a little but the chrome looks good. and i notice the other day that it leaks in the corners after a good rain so i will have to look into that.

Re: New to me 78 burb

I like your plan. There's been much more cam talk over the years in the truck section of the square forums and there's one guy in particular that always seemed like he had a lot of experience in getting the most out of stockish motors. Here's a thread for some ideas and the guy I was thinking of is Rich Weyand. Not to discount anyone else, but he used to post a lot about what you're thinking of doing. Good search fodder. Looking forward to seeing how it goes.

Re: New to me 78 burb

Well it's cyber week and i'm thinking about the edelbrock 2022 top end kit. it states you get 315hp with 381tq that is wonderful for me exactly where i want to be. I was wondering has anyone else ran this kit and how do you like it and does it run on 87 octane?

Re: New to me 78 burb

Cool burb! What did you find out about the alignment? I know your post was about a year old, but didnt see a follow up on that.

Re: New to me 78 burb

sorry for the late reply been busy in my garage working on aircooled vw. i did end up lowering the back a little more by pulling out another leaf and i did a 1 inch shackle because you can't do 2 on the side that had the gas filler it will hit the rubber and wear a hole in it so i ended cutting it down just below the top hole to give it more thickness which was fine. while i was at it i installed new bushings in my leaf springs. i don't know why everybody complains that was super easy with one of my vw dealer tools vw416b worked like a champ.
