    porting summit 85mm throttle body

    alright, so i'm a cheap bastard...i bought a 96mm intake manifold a while back to aid in my h/c swap. i'm looking at the possibility of getting the summit 85mm throttle body and porting it since it seems to be a cheap option. i am wondering if anybody knows how big it can be ported. if i can get it close to 90mm, i will be going this route since PP won't be able to get the 96mm throttle body out for a while. thanks guys.

    Never seen a Summit one, you'll just have to look closely at the area around the blade and port the remainder of the TB to meet it. I've been looking for a LQ4 TB in salvage yards... What's the Summit one run?

    ^ price is about $170. think i might look into getting a PP one though instead. should be able to get one for about the same price...and it's already polished.
