Default 402 low numbers?

Just looking for what y'all thought on my setup and what it made. Car Is a 99 Ta th350 4500 stall and a 12 moser 12 bolt 3.73 gear Motor was actually built for boost (about 9.1cr) but was told it worked well on nitrous too. West coast cylinder heads port matched 102/102 238/244 .620 lift 1 7/8 headers 3 inch x-pipe On motor car made 457/449 and it has a stand alone and a direct port kit on a .30 jet on nitrous side it made 646hp at 5600 rpm before the car raised above whatever it is that reads rpms off the crank pulley Haven't taken it to the track yet just wondering what y'all thought

Low comp and power robbing drivetrain was the converter locked?

Well I'm just wondering if I gained anything by going 402. I sold my 383 that made 440 on motor and 663 on a 225 shot for this motor. And it ran 7.0s on motor and 6.1 on spray. 1/8 mile

Have you compared the area under the curve? You're just quoting peak numbers.

I'm with the guys above though, I think the numbers are pretty good for the package.

My first time to the track I had a 5000rpm stall with the th350 and ran a 10.39@129mph 6.6@104mph in the 1/8th with a 1.41 60ft.. Run it before you pull it..
