IMO you'd be fine with 24's. Is this on a 302?

 

[rod196202]

yes 302 93vert.

A meter would definately help, and I'd go with 24s just to be safe, but nothing larger. You're going to need a larger fuel pump.

Use a pro m 80, and 24's.

Pro-M 80 and 24#

80 mm pro-m .... not an 80mm tb!!!!

The 65mm tb you have will work fine, you could probably use a 70, but the 65 will work. Get a 255 walbro pump, you could get by with a 150something, but if you get a 255 now (like $20 more) you will never need a bigger one.

(imho of course)

That 155lph fuel pump should be good for a 450hp engine.
