with the 327 you MAY and i say May drop 1 to 2 tenths and if u go straight to the 346 from the 307 I would say 3 or 4 tenths,, so u are now 10.99 , with the 327 you SHOULD drop to 10.8 or 10.7 ,,going to the 346 you SHOULD (no promises ) drop to 10.8 or 10.7, maybe a 10.6
it is easier to drop that first second,,after that 1 tenth at a time, when u think it should drop a second.

mine from 11.0 to 10.6,,, killer chiller ,two different pulleys , two different sets of rear DR;s , two tunes, open my exhaust , and rear gear change. all for just under 1/2 second., each little thing i got 1/2 of a tenth. Oh! 4 different Heat ex changer,,, now i have NO heat ex changers on my car. jim

 

AMX1397 helped me out with a center housing section,yoke and 327 gearing. Rob with the wavetrax and Rudy with the computer ratio mod. Devin with the bearings and install. They all worked well together but the rear end was shipped all over the USA. There was a huge take off improvment with the 327 with wavetrax over the 307 with wavetrax. I can only imagine how much faster the take off would be with a 346 gear with wavetrax. AMX1397(Jim) is the only one I know of that's making the 346 gear happen for us. Squirrel Crusher

 

Thanks SC ,you all know Rudy is helping me , I can't work my flip cell phone much less program a computer.. tcu. LOL. between Rudy, Rob, and Jim we can build it ,,ok Rudy and Rob

 

Well SC I will be getting g Jims 346 gears here soon if they test well for him. I'll leave my car at the 100 shot of nos for now I'll do whatever Robs coming out with and the gears. Hopefully I can take this v6 to 10.50s or 10.40s and the car is actually on a 98 shot to be specific technically not a 100 shot but yeah. I'm going to see how much forged connecting rods, better bearings Forged pistons etc... will cost and I'll run higher then a,150 shot then.

 

And veloc yes I think a bigger blower like 2.5 liters would do this car wonders. I'd definitely buy it.

 

Always wondered why people want to run a 285/305 etc on their close to stock SRT-6. Mainly for looks I guess. Unless road racing

 

Yeah I was thinking I might need a bigger tire however I proved to everybody that a lil 255 Dr can pull a 1.535 60ft it's capable of more to.

 

Jim... just tell what all I need to send you and we will start getting it together.

 

I can not wait for the 346 gears. Thankyou Jim! & I hope the testing for them goes very well.

 

between today and yesterday i put the diff with the 3.46 gears together about 5 times, getting all the measurements to make sure it is going to run smooth. I will try to take some pictures , just by my self working on it is more important than taking pictures,, we'll see. so far it looks good just need to get the backlash set to specs.

 

here are a few pictures,,, don't make fun of my tool box, it all i got. lol. jim

 

Perfect Jim that sounds good to me! I am very glad to hear that! Just let me know how it all goes in your car!.

 

Looking good Jim. Curious what the RPM's will be at 80MPH in overdrive with 26" tire height....Squirrel Crusher.

 

Looks spectacular Jim and I do not mind the tool box! It gets the job done! & when you finish/test it I will take my car to RRT and they will order/pay you and then they will install it along w the tcu. And we'll if I ever do am 80 mph roll I'll let you guys know how she does haha and Squirrel crusher it will be higher I would assume I guess only time will tell.

 

I will check that when it is installed,, you can change the rpm with tire size,, I am running 275-35-19 they are 26.6 tall and 285-35-19 are 26.9 tall and both fit on our car. My Dr's are 26.0 so i can test both sizes I am having some snap rings cut down to get the backlash so next week i will build and install into my car and test for a few weeks. jim

 

Jim do you think you will get to the track to test these gears out ? I hope and pray you can. So we can see how your monster of a car will do. And sounds good to me Jim!

 

I really like the exstensive use of "nos" in this thread, makes me chuckle. On the other hand...well done on putting together a quick setup. Get that mph up and then we can call it fast too.

 

Thankyou ! And it only has 3 passes on nos. This time and mph would be better if I was actually able to test it well.

 

Update the car ran a 10.957 at 126.89 still stock injectors and on a 100 shot that's with the car losing power from bouncing off the revlimiter 3 times each run 1.510 60ft on a 255 tire.

 

and this was done with a 3.46 rear gear set up,,,,and i have one 3.46 left for sale.

Chris, check with your tuner ,,see if he can up the rev limits,,, mine are 6700 and i shift out of 1 and second between 63 and 6500 just though of this. jim
