I'm lloking to install a 70mm throttle body onto my JG Edlebrock manifold. Now the manifold is already on the car. I understand that its nice to match port the TB to the Mani, but is it really worth the hassle of taking the mani off the motor just to have it match ported for a couple of mm's. Please let me know if I should bother or not. thanks.

 

why don't you just measure your edelbrock port and then find a TB with that size?

 

i have a 70mm TB on my Victor X and i had it port matched.
i think the Victor-X if you dont port it, its about 65mm so your going to miss about 5mm. Its up to you if you wanna get that lil extra air for more power.

 

The JG TB is 64mm and my Skunk2 IM was exactly 64mm so they matched perfectly.
