As I've said on previous posts i'm building a 393 stroker. I'm wondering if a 75MM throttle body will be a good choice for it.. I just a bought a 351w trickflow intake. tell me what you think?? Its also going to NA.

thanks

The 75MM is more than enough.

here's some more info.

AFR 185's please don't say to goto 205's because 1. can't afford them and 2. you need custom headers.
30# squirters

I use a 75 mm
I switched from a 70 mm and noticed a big difference especially on the top end.

mid to high 12's

I think the mph is 112 or so I really dont drag w/o the nos
It ran a best of 12.2 and 119.5 w/ the stock trick flow upper and floating valves(thanks to AFR's bad spring package) 295/35/18 bfg DR <hard to launch w/o spinning.Thats full weight w/leather and everything.

Hopefully 11's with new upper and bee-hive springs.

AND TRACTION!!!!!!!!!!!!!
