Need some knowledge. Can anyone tell if it would be a good idea to upgrade my T/B. I have a 70mm T/B, but the intake I purchased has a 75mm opening, it's the Trickflow track heat. I will be running this on a 331 with a 73mm maf, 30# inj, and the Trickflow top end kit stage one.

The 70mm will be ok for your mild 331.

70mm will be fine as my lil homie from the NY said, but if you can sell yours and swap up for pretty much close to nothing, do it.

You won't gain anything with a swap, it will be negligable. If you do decide to do it, get a back to back dyno (same day, two pulls apart)...
