Dynoed my cheap 383
Here is an engine I just dynoed. Thought some of you might find it interesting. Put together with mostly used parts I had.
1970 383 with the original cast pistons. Ball honed and new rings. All new bearings.
516 heads I mildly ported and installed used 1.74 exhaust valves. Compression came out to 9.4 to 1.
A serdi valve job and cut the guides for viton seals.
A lightly used Elgin cam with 224 234 @. 050 and 465 488 lift on a 112 LSA. New lifters.
Used Mopar performance valve springs.
I reused the oil pump and double roller timing gears.
Stock intake with a 750 dp and headers it made 380 hp at 5600 and 408 ft lbs at 3500. We didn't start the pull earlier, so it may have made more torque lower. It lost 12 hp with the original AVS, but it was a bit rich.
