75mm throttle body to small

[95StocK50]

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.

maybe too big I would say a 70 MM is about all you would need

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


would you say it would be to big???

I thought their was a guidline on this on which throttle body to chose... like if you have this much hp you need this TB..??? no

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!!!!!!!!!!!!!
