I had built a 505 stroker. here is the list of parts: 440 bored .30 505 stroker kit from Ohio Crankshaft 84cc Edelbrock heads with stock rocker arms Edelbrock Torker 2 intake Holley 850 carb HYDRAULIC − Serious street and bracket race cam. 10:1 compression, lower gears, headers and 3500+ stall. Hyd. Hyd. 3000 to 6500 21-229-428 Single-Bolt XE295HL 295 307 251 257.564.564 110° Dougs 3" headers
Took it to the dyno and it only put out 231 hp and 286 torque. I lost probably about half the horse power somewhere.

Are those rear wheel HP and TQ numbers?

Stock rocker arms? Is that meaning stamped steel? If so get rid of them and get some adjustable's. That's a pretty decent hyd cam should make over 600 hp easily. Degree the cam? Break in the cam with proper lube? Yes,stamped steel rockers. Broke the motor in with Joe Gibbs oil. We did degree the cam. Hot rod magizine built a 573 hp and used stamped steel rockers so I doubt that would make me lose that much hp and tq. http://www.hotrod.com/how-to/engine/1412-how-you-can-build-a-stout-537hp-street-440/

I hate the intake for that combo, I hate the convertor choice for that combo, did you check for total timing in the 32-36 range for a start. Did you check for proper preload on those non adjustable rockers.
1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.38@138.67
Livin and lovin life one day at a time

I don't see any problems with that parts list so I'm guessing the tune is way off. Do the standard checks and see what you find.
Spark plug wires connected? Plug wires in the correct order? Compression check? Look at plugs, look at ports, etc. Vacuum leaks? Air Fuel ratio? Ignition timing? etc. They did change the plugs and upped the jets to 88 and 90. They reset the timing to 34 degrees. I have the dyno sheet at home and I’ll post it when I get there. It’s a very well Mopar place in Michigan that ran it on the Dyno and he can’t figure it out. Very disappointing

Wondering what you used for push rods and lifter preload?
Do ya got a vid of this dyno session or of the car running, id think it probably dont sound well when running either. I do have a video but have no idea how to post it here

I had it dyno’d at Jake’s. He’s a Mopar guy so I don’t think it’s the dyno I had my car checked at Jakes also... did you ask him what might be your issue(if he throught there was)

Something going on besides the jetting or the timing being off a few numbers. Compression test, leak it, get the timing cover off and check the cam timing. Cut the oil filter apart and check it. Exhaust blocked. Transmission OK. Has to run and sound bad when it's being driven.
If the results don't match the theory, change the theory.

He was going to ask his buddy at Modern to see if he had anything and get back with me. I believe I'm going to pull the motor and dissect it and maybe something will show up.

Exhaust blocked. Transmission OK. Has to run and sound bad when it's being driven. Did all that. Did the compession check and leak down and everything looked great. Trans is good. I just dont know. I sank and boat load of money in this thing and my Ford Focus has more power!
