Just a quick look at my future combo...
I won't give away 'the farm', but:
362.49 cid
10.085:1
Aftermarket W heads
Off the shelf intake, carb, headers, etc...
Pk tq: 499
Avg: 348
Pk hp: 537
Avg: 289
Vol eff: 108.4%
HP per cube: 1.48
Analysis Report for Street/Strip Engine with Desired HP Peak at 6000 RPM
Peak Tq =499. @ 5000 RPM 1.38 Ft Lbs per CuIn
Peak HP =537. @ 6000 RPM 1.48 HP per CuIn
Maximum Tq/CuIn is 1.377 Ft Lbs/CuIn.
This is somewhat high, indicating good performance, but will
produce high cylinder pressures and temperatures.
Maximum Exhaust System Backpressure 'Exh Pres' is .6 PSI.
This is typical for a street/strip vehicle with a free flowing,
full exhaust system. To simulate open headers, select the
'Open Headers' from the Exh System Type combo box.
Maximum Fuel Flow 'Fuel Flow' is 267 lbs/hr GAS.
This is equal to 45.7 gallons per hour of fuel flow.
For an injected engine with one injector per cylinder, you will require
at least 33 lbs/hr injectors.
The Intake Valve Mach # 'MACH #' is .396
at your 'Desired HP Peak RPM' of 6000 RPM.
This is low and indicates perhaps too much intake cam duration.
The Maximum Average Piston Speed 'Piston Spd' is 3500 ft/min
at the Performance Calculations Maximum RPM of 6000 RPM.
The Intake Runner Velocity 'Int AvgVel' is 316 ft/sec
at your 'Desired HP Peak RPM' 6000 RPM.
This is somewhat high and indicates you will need a larger Intake
Runner Diameter or larger Intake Port Diameter for less
restriction and stronger intake tuning.
For these engine specs, an 'Int AvgVel' of about 250 should work well.
If the 'Int AvgVel' is approximately 30-80 Ft/Sec higher than this,
you will likely improve torque below this RPM, but lose some HP.
The Inertia tuning of this intake is tuned to 5515 RPM,
which is close to your 'Desired HP Peak RPM' of 6000 RPM.
Since this RPM is about where the HP peak should occur, peak HP
should be good. If you specify longer and/or smaller diameter intake
runners, you will likely gain Peak Torque and lose some Peak HP.
Estimated Idle Vacuum 'Est Idle Vac, ''Hg' is 3 ''Hg.
This is Very low, and will likely NOT idle well or provide
enough vacuum to run vacuum accessories for an engine which is used
occasionally on the street.
