How much power should I be making?

Hi,

I've got an 85 LG4 305 Camaro with the following specs:

- 14014416 heads
- Mild performance cam (honestly no idea which one, sounds mean but doesn't tell anything about performance)
- Edelbrock 1406 carb (600cfm)
- Performer intake
- Shorty headers
- 3" exhaust, no catalytic converters
- refurbished HEI ignition

Runs good after some carb / timing adjustment. What sort of power should this be putting out? Would be cool to have a reference point if I ever get this on the dyno.

I had about the same setup once except with a 650 Holley DP which is a lil bit more of an upgrade over the Eddy. Had a K1104 cam. It ran 14.8s so I would put that at about 200-215 HP.

Re: How much power should I be making?

Go to the drag strip . Get some ET slips.
The MPH tells the true power tale.. Weight the car with you in it.. Its that simple.
If the heads are stock as cast keep your expectations
modest.
A 100 mph ¼ mi trap speed needs a .0773 weight to power ratio. If the car + driver weights 3500 # its makin 270 net rwhp.

Can you hit 100 mph in the ¼ mi.
Go to your local track and find out.
The ET does not tell you about power.
The ¼ mi MPH and car+ driver real weight does..
The dyno is for measuring effect +/- of tuning and parts changes.

The 4416 heads are very modest in stock form
Get much better with tenerous porting and bigger valves.


Now you have a true engine power performance
measurment and a baseline to work with to make changes and tune it for better power and performance.
