You almost have your motor together? How does it turn 3000 rpm at 45 mph if it's not together yet? I'm confused.

well the sbc thats in it now turns 3000 at 45 mph the stroke,rod length are the same in this motor so the rpms should relatively close to the same im thinkin......as far as i know everything in the tranny has to spin at the same speed to go 45mph with this motor as well as the one in it now

i disagree.. the guy who built my 383 budget motor i ran in my vega figured it would run 11.20's and it ran 10.60's in the 1/4 mile after a lil tuning and my bro's 355 in his vega runs 10.30's and both are on motor only and a 2 speed glide... really depends on the cars weight and motor setup..cam/timing/heads and gearing ect.

Point being, Benchtop Math doesn't do much more than aim you in the right direction.

Take it to the track, see what it does and then use that as your baseline for improvements. It really doesn't matter whether it runs a 14 or a 10 on it's first outing. To use a tired Cliche; "It IS what it IS" . . .

From there you make adjustments . .

Probably the only constant I have when talking about Racing Engines is the "Horsepower" thing. Horsepower numbers are good for two things.

Tuning when using a Dynometer, or bullshitting the novices in the bar . .

The numbers we all really care about are 60' time, ET, and numbers of final rounds ran . .

Sometimes MPH comes into play but usually only when qualifying or messing with the other lane in Bracket racing . .

Heh, heh . . Over the years, I have come to the conclusion that the 60' time is, in drag racing, the most important number you can be concerned with. Granted, ET and Top end RPM are numbers you always want to watch, but the 60' time affects everything after the car's first movement. A consistent 60' time will guarantee you a consistent ET and dial in, generally.

And, it's usually the number that's affected by track condition. Of course, if your 60' time is affected by a hot or greasy track, then of course, your overall ET is affected. This is where suspension tuning and tire pressure is really important.

In Brackets (no secret here), a pure 60' time, and the same 660 ET on each pass will generally guarantee perfect split times at the other end . . And this is true whether you run 4's or 14's . .
