Ahh, yeah, I didn't take into account that you were shifting at 4500, I was thinking 5500---too high for a stock 250.
When I was first racing my '70 Camaro back in the early 2000's (2000-2002, I had 2.73 gears, a 3000 stall converter, and a mild 350 (~350ish-hp). It seemed like I could go to half track (660ft) before I shifted into second (5500rpms), and then went through the traps (1/4 mile) around 5000 still in second. It ran 13.80's, had drag radials so it didn't spin a lick, and would run that number all day long. Then the speed bug bit me, and in went a 10.5:1 406 with AFR 210's, solid roller, big carb & exhaust, 4.10's, 4000 stall, etc, and got it down to 11.0's at 121 w/ 1.50 60' times. That was a fun street car, but now it's torn apart getting the pro-touring treatment...after the truck is finished, though. lol
I'm building my truck to be a fun cruiser with a little bit of power, but didn't need something else that was super fast. That's what the Camaro is for.
That was a very good and informative write-up. For my 250, I could probably go with either and make sufficient power. But since I'm going to drive it on the street (A LOT), the benefit of the Offy intake's heat exchanger and slightly better low end power should do well.
Thanks,

BTW, what year Nova do you have?
