Glide or TH350??? Deep 10 Sec NA Car goin for 9's... Ok looking for some input of the serious drag race guys out there......gonna be switching out the good ole 4L60E and the 4800 9.5" Vigilante for something a bit more race appropriate.....the 4l60e did a good job so far but i know the car would benefit greatly from a real race trans and not a street designed trans.........heres some info
Car will be 3300lbs with me in it next year......
385 CI w/ over 13:1 CR
AI TFS 215cnc Heads
AI Custom Solid Roller
Single Plane Conversion
Motor has a nice flat spot of peak power between 6700 and 7900.....makes peak torque a hair over 6000 and peak power at 7400
So far i went 10.26@ 132 with the car at a 3470lb race weight, I've got a TH350 laying around that I can build and put in the car but I'm wondering what the best option is for the car...a transbraked manual valvebody TH350 or a transbraked powerglide.
Looking for some experience out here????
Tryin to keep it a interior car thats not competly hacked up for weight reduction and put it well into the 9's on motor.....
Thanks!!!!

I am running a Th350 and plan on running 10.30's or so on motor and deep 9's on spray but when this Th350 gives up a glide will be replacing it. I should sell it now and swap but the setup that I have now was working well before so I don't feel like starting over with the trans. You are starting from scratch so I would build a glide and be done. There are acouple LT1's running glides and they all work well, Tony, Jake, Ken A, a few more run better on motor going from 4l60 to glide but the converter will have to be spot on and your gears may work ok.

If you look/wait, you can find them used with JW bell housings, shields etc for about that price. Those SFI shields can be 400 each new.
I ran a th400 and take it from me...lose the weight and run the lightest trans you can get to hold up to your needs. A PG could easily hold up to the power you are making and have one less shift. A PG is also a pretty good weight savings over even a th350.
Then comes in the converter. There are options that weigh a ton less and can MPH higher than your current setup.
I'm not sure how much street driving you intend to do with your new setup, but all those above factors should be considered with the track vs Street issue in mind.
PM me if you want.

isnt the objective here to go as fast as possible? why is the 2.58 better then the 2.75? i figured he would want the best short time he could get.

My car has been a pure race car for 10yrs and I've had a th350 and it worked fine, but if your doing nothing but race, a PG is the ONLY choice. I once thought as some do that my car was to heavy (3200+) to run a PG, well I was wrong. I swapped in a PG with a 1.76 first gear and custom built converter from Camerons Converters in Coluimbia SC and instantly picked up .15 in the 1/8 mile with no loss in 60ft with 5.13 rear gears. I later installed a 1.96 first gear set and saw little to no difference except for the chest high wheelstands.
I built my current engine and went back to the 1.76 first gear and was tripping the 60ft beams with the back tires. After many adj over the next few months I got the car to stay down around waist high, until I swapped in a custom ground SR, and I was right back dragging the bumper. So I swapped in a set of 4.56 rear gears and that's where I am now leaving waist high with 1.32-1.33 60ft in a 3200+ car with a 1.76 first gear and 4.56 rear gears, which equals out to a 8.03 tq multiplcation. Go with the PG and you won't be sorry. Oh, and by the way a th400 is junk for racing, there like hp sponges.

LOL, complete bullshit.
You can make a TH 400 take LESS power than a stock 350.
I have personally seen the swap from TH 350 to TH 400 both built with stock parts on a DEADLY consistent bracket car and the ET drop was NILL.. Nothing.
A PG is a great trans for drag racing if the car is setup for it, no doubt about that. But calling a T 400 junk is just retarded..
The added strength that can be had from the T 400 compared to a 350 makes it worth it every time to me.
