I'd say about 250 HP, of coarse that's JMO

another way is to run the 1/4 mile and use an estimator

For instance, if a truck weighed 4000 lbs with the driver and ended the quarter at 77 mph, the estimator says 168 Horsepower. Your numbers may vary, slightly higher in the West, not available in Blue states.

I don't want to cut on your combo, but it is really badly mismatched. Your cam is pretty big and should make some horses but the 305 heads killed it. They're good for bumping the compression, but flow is way low on them. The accelerator intake is OK only if the divider plate is in it. You would run much better and be at about 325 horses if you could find some better heads and go to a Performer RPM intake. If you could get some vortec heads, that would be great. Those 305 heads and single plane intake won't work well with the big cam. The intake would be ok with better heads, but the RPM would be better all around.

I forgot to add that the Accel cap and rotor is great, but you also need a better coil and for sure a better module. The cheaper is Accel module and it works great.
