V6 to V8 swap

Well I just finished my v6 auto to v8 t5 swap. It wasn't as bad as i thought. it every bit of spare time that i had for a week, but it is done!!!! I still have a couple of little things to work on, if anyone has an electric speedo sending unit for the tranny, please let me know, i'm driving blind..... Anyway, if any one is thinking about doing this swap and has any questions, just let me know, i's happy to share my experiances.

Hi, I'm considering a similar swap... 85 Camaro 2.8 FI V6 to a carbed 305 or 350 but still retaining the stock transmission. What all is involved in the motor swap?

Thanks!

Nevermind... found all the info I need. It looks like the swap might be somewhat of a PITA, I'd be better off starting off with a V8 car.

Don't get discouraged. I won't lie, it was A LOT of work, but it wasn't that difficult. Will that tranny from the v6 hold up to even a 305??? I would think that the 8 would leave that tranny lying on the ground in a bloody pile. Anyway, the swap was just merely changing the motor mounts and dropping in the new motor.

pretty sure v6 tranny wont bolt up to a v8. it has a different bolt pattern plus it is a 26 spline and v8's have 30 spline.
