i have an 86 Iroc z camaro that originally had a 305 tpi and an automatic transmission and i have swapped it to a 350 tpi with a t5 manual transmission i was wondering what kind of issues that i may run into and if anyone knows how to remedy those problems. thanks for any solutions that i can get.

 

EXTREMELY short transmission lifetime, if you abuse it AT ALL

Get rid of the weak T-5 and swap to a T-56


The T-5 will do just fine if you drive it REAL EASY: no traction, no burnouts, no clutch dumps, no speed shifting. It might last a hundred thousand miles. Do any of those things though, and its lifetime will likely be measured in milliseconds instead of thousands of miles.

 

Not to mention the computer/programming issues

 

You need a 350 knock sensor , 350 injectors and a 350 prom in your 305 computer

 

I did the same swap in my IROC. The t5 has held up fine so far, including a couple trips to the drag strip every year, with a best of a 13.6@101. I'm going to tempt fate and keep the t5 after the vortec head swap.

Some t5s break right away, others hold up if the motor is mild and you don't thrash it. I use mine, but I don't abuse it.

In terms of issues, a custom PROM, proper injectors, and a 350 knock sensor should do it.
