Went to the dyno this morning....

Electric pump, regulator set at 7 psi and (minimum) 3/8" line from the tank to the regulator. Use a 1/2 pick up in the tank or better yet add a sump with 1/2 " NPT bungs.

Need to KNOW the compression ratio and the cam specs to KNOW where you're at in producing (or not) the power.

915 heads don't do much if the pistons are .080 in the hole. Cam duration and CL both ground and installed are critical. If the cam is 270 at .050 for example, it's going to have a hard time making torque with low compression.

It the very minimum I'd pull the heads, have them flowed, evaluate the deck height, get the numbers from the cam and go from there.

A basic, flat top 440 with even mild heads and cam should go 400-425 HP on the dyno and have so much torque it'd be hard to keep on the rollers.

If you took it to the Jake I'm thinking you did, RIGHT THERE is a GREAT source to waking her up!

Yes, a HIGH-FIVE to the bride...Way cool wedding gift!
