I think there are a few on here that have them. I've started looking into it and it looks like a viable option that will be about the same cost, maybe a little more than a th-400 swap from my M6.

Harlan, I hope you can chime in cause I know you were thinking of going this route.

Jerico quoted 3200 for a DR4 4 speed with roadrace sliders and about all I need is a bell housing that I guess Lakewood makes and a driveshaft. They said a stock type clutch would work with some changes to the throwout bearing.

the only thing I don't really like is 4th has to be 1:1. but it's reliable to 1000hp.

I'd just like to know what issues you ran into and how you like it?? any input is appreciated.

TIA!

 

ttt....
interesting topic!!

 

contact SAM. website is on your right.

 

sam helped me out. I'll update you guys when I get more lined out

 

john, what is wrong with a 1/1 gear in 4th?

 

I thought about going this route but didn't want to be a guinea pig. I know judson is running one. I'd get 4th gear setup to be overdrive if it was me. I'm curious how they are on the street and downshifting and such.

 

this is really starting to be interesting. looks like there could be an alternative. it certainly would be a 10/10 on a coolness factor! the price of a total TH-400 with transbreak, conversion, and nice convertor (say yank or big boys like neal chance units) easily surpases 4000+ dollars. if a jerico could be done for that same money i think it would be great. but straight cut gears scare me and i want more input on this matter. i bet we could get this thread moving! any jerrico guys out there (non-ls1 as well)?

 

I have a buddy in town with a 55, has a DEI busch motor in it with a Jerico. He just took it out and put in a Tremec. Lots of gear noise on the street, grinding, etc. BUT... this type of trans is excellent for race and lets us move to a real clutch assembly!

 

guess I was hoping for an OD 4th so it would be a little more streetable. the 5 speed won't even fit in an F-body.

 

so make it fit

 

well, they said MAJOR modification and it costs quite a bit more.

 

How about the G-Force 5 Speed?

 

I browsed their web site and called. it was about another $1k for a 4 speed and the 5 speed is $1500 more on top of that. I was trying to keep it at a fairly reasonable cost

they also didn't know of any ls1 applications done yet

 

ok... all's I need is a lakewood bellhousing $300 and a different slave $250 and I'm ready to roll. looks like about 3750 on the road. should be all bolt in. no modifications.

then when my mcleod twin disc goes out I can upgrade to a 90% drag setup for about 1300, but then the pressure plate has to be adjusted for street to strip use.

this should be done by early spring/late winter as long as my contract gets renewed in janurary.


I need a beefy driveshaft anyway, but that will have to change also.

 

I take that back... there will be some fabbing with the tranny mount

 

dude, add that up..

3200 -trans
1300 -clutch
300 - bell
250 -slave
300 - ds

thats 5350.00 worth of crap, just to say that you've got a jericho. how much faster is it going to make the car? consistant? if im spending that much all at once, it have better put me in th 9's.

if you've got the dough to do it, man, knock yourself out, but personally i'd rather have a c5r headed solid roller motor and live with the t-56, and a street twin. for what you're talking about spending. heck, make it a race twin. for that much cash, you could have a spare motor and tranny around as well.

just my .02 though.. my apologies, im in a ranting mood lately.

 

I don't need the clutch. I can run my mcleod twin disc. I was just saying I could upgrade to a more pure drag clutch for 1300 if I wanted.

I need the driveshaft anyway, so I'm spending about 3750 on a bulletproof transmission.

if I want to spray and go deep into the 9's my T-56 won't hold anyway, and the jerico will be quicker also. I can shift without a clutch 2-4 and select whatever gear set I want.
so yes, it will be faster and more consistant. no missed shifts and quicker shifting.

my goal is 9's NA with my 383. I know it's really pushing it, but in great weather and great track it may be possible in the spring. AFR Heads and LSX or sheetmetal intake would also be added.

 

sounds like a cool goal but it's gonna come down to a wire.. good luck

 

I have been thinking about a trans swap too, so if you are in the mood to read a long post...
To keep a working speedo with the Jerico you have to run the 4 speed. You can't get the 5 speed with a speedo drive, but it sounds like it won't fit Camaros without a bunch of work so I guess its a moot point anyway.
I have heard the noise thing mentioned many times, but have never heard one in person, that is a concern of mine too. Probably sounds like being in reverse all the time, put some sound deadener down and live with it I guess.
I called Jerico twice, the first guy wasn't much help with questions about a Camaro swap, but the second guy I talked to seemed familiar with it. He said other than having to beat the tunnel for shift linkage clearance it shouldn't be a problem, and if you get what they call the road race sliders you can downshift ok. I also talked to a guy at Thunder Racing about it, coincidentally he was considering the swap for his car.
On their website the SAM car even has the stock console. I emailed them with a few questions. No answer back, but it sounds like 383ss got a reply so they might share some info with him.
I also called G-force, the guy I talked to said they don't recommend driving theirs on the street, he said it will wear out quickly. I didn't really get that, from what I had seen that's what the thing was designed for in the first place? As another alternative, they do offer a face tooth kit for the T5, but they are not positive they are even going to offer a T-56 kit at all, and if they do it might be a year before its available. They also offer a modified kit where they take every other tooth off the synchro so it powershifts better. Its kinda half way between synchronized and a crash box like Liberty makes. You can powershift a Liberty easily, but sounds like too much of a pain on the street to seriously consider. The guy at Liberty I talked to said you can't shift them slow without double clutching so its powershift or dump truck.
Now that Lakewood has a scattershield, and trans x-members aren't hard to come by this is starting to look doable without having to fab up a bunch of stuff. And the guy working on the no torque arm rear suspension helps this out even more.
But as they say, this is just my .02 worth -or for a post this long maybe a nickels worth??

 

That Jericho 4 speed is bad ***! My uncle has a 69' Z28 with a pretty stout n/a, high reving small block, 12 bolt with 5.38's, 10.5" et drags and a 4 speed jericho tranny. The car is street legal, but he rarely drives it on the street, it's a pretty high compression motor. Best time to date is 10.87 @ 126. That tranny is tha ****! My uncle loves it! It's alot of fun to watch him bang some gears, it almost sounds like an auto. He has no complaints with the Jericho, he says it was well worth the money. So, get the jericho!! I have some videos of the car, at the track. So, I'll post some vids if ya'll wanna see them.
