Horsepower/Torque
Have a question for everyone to give me they idea of how much horsepower and torque my combination will make. Once it is built and broke in I am gonig to have it dynoed for the hell of it to see what it does then I will post the results and we can see who got closest.
350 bored .040 over Flat Top Pistons Comp Cam High Energy 268/268 Duration .454/.454 Lift Edelbrock E-Street 64CC Aluminum Heads Compression about 9.3-1 Edelbrock EPS Aluminum Intake 1.5 Roller Rockers 600 CFM Edelbrock Carb I am building it for low to mid range torque and was just wondering what everyone was thinking it is going to make? Lets calculate both flywheel horsepower and wheel horsepower |

Re: Horsepower/Torque
I am just taking this off the top of my head but I am guessing around 345rwhp.
Of course I could be way wrong but each engine is different. Good luck.

Re: Horsepower/Torque
The info needed to get an accurate guess is as follows:
Motor Size: Juice: Timing Curve (initial and total): Compression: Air Induction: Air Conditioned: Carburetor: Intake: Heads: Head Extras, (if you have flow specs, or a link to flow specs, that would be great, heads can make as much as a 50~75 hp difference): Camshaft (specs or cam card link please): Cam Retard/Advance: Headers: Exhaust: And if you want 1/8 or 1/4 mile times, this info is also needed: Transmission: Converter Stall Speed: Tranny Extras: Rear Gears: Posi, spool, or open diff: Tires/Slicks: Tire Height: Traction Adders: Weight: |
