hey Jim,

are you going with a big *** rear wing to keep your car from going ariborne at 280 mph?

can I take out a life insurance policy on you?

Jim, if you dont mind me asking how much does that Jerico trans cost? Do they basically let you pick the gearing you want when you order it?

I think your car needs to be at least a low 10sec car in street trim with some BFG drag radials. Mid 9's with a 220 or so top end would even be better. Wouldnt that be nice!!!!!

Thanks,
STEPHEN

$6,500 minus options. You can select from a huge range of gear ratios, and they custom build the transmission to your specifications. These are the same transmissions used by Winston Cup cars.

kind of a dumb question here, but how do you know the Jerico (or any other make for that matter) will fit inside the narrow trans tunnel? the stock FD trans seems pretty narrow

Because I know that a TH-400/460LE automatic case will fit in the transmission tunnel and still leave room for exhaust. The Jerico case is very small, actually.



Here's the external rail version...

Speaking of Chevy-derived trannys:



Here's one backing up a 13B, for drag apps.

Jim - Do you have a job?

Hi Jim –
It’s been a while since I read this thread. In fact I did a search to show it to a friend.
In the 80s I was able to drive a 4 speed Jerico and a Nash 5 speed both with straight cut gears. I would not recommend it for the street. You are either in or out of gear with no forgiveness. “Very precise and (KEWL) for racing.” I would not recommend it for street.
That was a long time ago and I am not up on current technology. Maybe they figured it out but I think that driving in any kind of stop and go traffic would get on your nerves
“QUICKLY’.
I would suggest side cut gears. I have also driven several cars that had Doug Nash 5speeds with side cut gears. They were very nice. One of the transmissions was mine and survived through 2 cars.
Just my $.02
Keep up the great work

this might be a dumb question

any pictures if anybody have it
cost , time ect.

thanks

Wow, surprised i never saw this thread...

Jim the 9" looks like your best best. The C4 rear suspension is a complete joke, camber control depends on the condition of the differential bearings and the spider gear shaft thickness, because they use the halfshaft as the upper link - I have yet to find a C4 that didn't feel sloppy, like bad upper ball joints would feel.

I don't agree with you on one point, though... the chassis will still try to twist, simply because the engine os torquing on the chassis. I have yet to see an IRS car launch hard enough to pick a tire off the ground, which is saying something in itself But going to a solid axle would be some serious hackery of the car...

The T-bird IRS will take goodly amounts of torque thanks to the available 8.8 diff. A friend of mine made some brackets and literally bolted a late T-bird rear subframe up under his '55 Chevy pickup street-rod. It has a healthy 355 in it now, all it needs is the 6-71 on top (coming soon) and we'll see how much torque it can handle The old solid rear is now under a similar '57 pickup 'rod, which is getting a Z28-spec 302 in addition to the usual fiberglass panels, IFS, etc. Still trying to convince him to go the IRS route as well
