My 3.1L/3400 hybrid build

[fasteddi]

Well im doing a TH350 swap for many reasons, maily because this is a bracket car and the old 700r is about to die. So here is the progress so far.

Here are some pics. I ground down the areas for the bolts from the plate to the block, also slotted the flywheel for the 3/8ths bolts for the TC. I got my gears and such for the speedo housing. Got it all installed. Tossed on the Vss 4k ppm to make sure it fits....and it does like a glove.

I need to still do a bit more but I made alot of progress in 4 hrs including tearing out that ole 700r4.

I still need to get some grade 8 bolts for the plate to the new trans and from the flexplate to the converter, but else then that its just a bit of fabrication and i can toss it in.

nice.

will the gearing improve your times you think? or is the gearing any different?

[fasteddi]

I think it will help. The 700r4 really was starting to slip and the converter was way past it's tq capibilities. The gearing from 1st to 2nd is much better. Alot closer unlike the 700r4 which had a huge gap between the 2. I think I'll go a bit faster. not too much Mabey a few tenths or so but it will be a reliable trans that is ment for the power.

Update the trans is in. Went well.

Those top two bolts on the housing will be fun to tighten down. They are alot more tighter then the V6!! I tacked the bolts heads on those to the adapter plate so the trans easily slid right on there. I tossed it in myself on my gravel garage floor...fun!


I still have to tighten up those top bolts, tighten down the TC, get the trq bar mount on(i got a used b&m adapter for 45 bucks shipped) and then just little things. But its too cold out to do that stuff right now. Im just happy the trans fit right up in there, the flex plate went on with the TC pilot adapter fine, and the trans mount adapter to shift it forward 1 5/8th of a inch worked. Although there was some extra adjustment i could have gotten out of the single bolt on the bottom of the trans mount to the x over.

Looks great. I bet you can't wait to get it out on the track.

[fasteddi]

Thanks. Definitly can't wait. I'm getting tired of these ohio 0 degree days.

[xpbr2000]

no doubt. gravel + cold= total suckage

Update!

Well 5 months after I winterized the camaro... it fired right up. Now with a TH350 behind it. Ran it for a bit to make sure the fluids were all ok. Im running a new rear end girdle, a new 2 row alum radiator, and dual fan set up also.

I did notice a little bit of vibrations with the new poly mounts for the trans. Its not violent or terrible but it is noticable and only at idle. Rev it up and its almost non existant. Im hoping its that (the new poly mounts) and not the flexplate or TC since those have been modded just slightly.

I still have to mess with the shifter cable and get it dialed in right before I can drive it, along with a few other little things.

But bracket racing starts may 3rd. So i need to get this car up and ready to tune within the next month. Im getting the itch!

[xpbr2000]

LOL i'll bet. I do not envy you northerners having to put up you car for months.

[fasteddi]

Yea it is rough. We had a stretch where the temps never got above freezing for 26 days iirc. February was a record cold month here in toledo. One day I'll move where it's warm all the time..
