First off i have a 93 lt1 with the OFI single kit im looking into some transmission help. I have a stock 700r4 and dont really know what i need to be able to handle around 500-600 hp that i plan on having later on. I will eventually run about 12lbs of boost once i finish the forged motor. Ive looked at this site for stuff so far http://www.700r4l60e.com/store/customer/home.php?cat=19 im not gonna lie it looks cheap and gets the job done but im just trying to see what other lt1 users have for a built trans(i want to stay auto as well i know im going to need to do alot of work. So let me here what you think i should do or what you have done with your lt1's. thanks for any input

P.s Id like to stay with 700r4 since that why i save some money not having to buy a new trans as well along with the build.

What size turbo are you putting on the OFI kit, which did you choose A/A or A/W ? I think if your gonna do the tranny on the cheap it probably won't last long with 550 to 600 rwhp without a substantial build-up. JMO

off hand i think its a t67 and A/A it says it will handle that much i just dont have the funds for 2000 tranny because i know i will also need a new rearend and incase anything else goes as well. what other tranny options do i have or suggestions?

The 700R can take a beating.

Dont think that its going to fail immediatly, but it will eventualy.

You can buy a TH350 and have it race-built for less money than a simple overhaul on a 700R4. I broke 2 4L60E's at 500 rwhp before installing a $750 TH350. The TH350 has seen anywhere from 500 to 750 rwhp and I've been running it for 2 years, beating on it weekly, and it's been flawless.

The Th350 bolt on wright???

engineermike

I'm not sure what you're asking, but I'll try and answer. The Th350 has the same bolt pattern where it meets the block. Also, a TH350 converter will bolt to the LT1 flexplate. On the other end, if you use a long-tail TH350, then the stock driveshaft will work. I used a BMR trans crossmember and a B&M torque arm mount.
