318 LA hp and torque question
Im new to the mopar world so I would like to ask a question regarding my 69 notchback barracuda w/318 La. The book states this engine is 230 hp @ 4400 rpm and 340 lb torque @ 2400 rpm. It is bone stock with the orig. intake and 2 barrel carb and single stock exhaust. If I install a SP2P 318 edlebrock alum. intake and 600 cfm carb. along with dual exhaust what kind of hp and torque increase would I be looking at? Thanks
Going by your 'original question'.
The 318/230 HP puts out closer to 195 Gross Horsepower @ 4100 RPM's.
Torque read outs are around 305 Ft/Lbs. @ 2500 RPM's.
By adding a decent Dual-Exhaust system {Exhaust Manifolds, 2.25" Exhaust Pipes, and Low-Restriction Mufflers} {ie; Mopar 340} you should increase Horsepower by a minimum of 12% {or 23 HP}.
The 1969 318/230 HP came thru with a Carter BBD {285 CFM} Carburetor.
If your replacing the Intake and Carburetor with an Edelbrock S2P2, and
a 600 CFM Carburetor, you will probably gain another {12 to 15 HP}.
The Edelbrock S2P2 is really designed for low-end Torque, and is not
effective over 4000 RPM's for horsepower increase.
