ok i have a little stipulation here. and this is kinda long so bear with me. i currently have a 200-4R tranny rebuilt by jimmy's trans of mundeline IL. it has kevlar bands, hardened steel clutch packs, GN servo, trans-go shift kit, a 2000 stall manual lock-up converter, and a few other things i can think of right now. this is just the basic rebuild kit. i asked him if he could build me a race type trans for the car. he said he could, but doesnt know if it will hold up. i will be putting a 357 in my car in the future (not any time really soon as im broke right now) but it should make between 450-500hp rough estimate on motor. i will have a NX kit hooked up to it. and depending how comfortable i become with the car, i will shoot up to 250 at it. this is where jimmy has a little problem. he doesnt know if the trans will hold up to repeated abuse of a 200+ shot. im not gonna bracket race it, or be racing all the time. but plan to make my fair share of passes. i really really like the 200 for the over drive and lock up converter with my 3.73's. now im kinda weary about spending 1500+ on a race trans and having it break and have to get it rebuilt every year or so. i dont have that kinda cash. so i have a part way solution, this is where you guys come in. i have a th350 i pulled from another monte, needs to be gone through, but is pleanty capabale of handling the motor mentioned (just from seeing what other people have done with them) . but i dont know how the trans will be on the road. i want super drivabilaty, cause it isnt going to be a race car. i want to drive it every where and back, with out running out of gear on the street and having to fill up every 2 blocks for gas. so does anyone think the 200 is actually cabable of being a strong, and trustworthy trans to build, or do i go with the 350. i need to figure out what my losses would be in the change. and i know im gonna need to change the drive shaft out. no worries about that, cause im putting a 8.5 in the car, so i ned a new DS for either trans anyway. i would also need a th350 crossmember, shifter linkage, and possibly a new speedo cable. anything else id need to change? the last thing, but probably the smallest. i have already purchased a iceman cross member for a 200-4R and sent it out and had it powder coated (red). it hasnt been installed yet, just sitting in my basement. has a few nicks from moving it around but other wise perfect. but now id have to sell this crossmember to get another,or if i could possibly work somethin out with ice man, get a th350 one in exchange plus a little somethin. just need to know which will be better suited for lots of higway and around town miles, with a little racing action on the side. thanks in advance.
