I built this engine years ago to put in my mother's 68 road runner in place of the original 383. It has been on the stand for a long time as garage art. LOL
It has now been 10 years and I wanted to see what it makes for HP and torque. So, it went on the dyno yesterday.
The rotating assy is 440 Source, Ross pistons, the block zero decked, Edelbrock RPM heads were checked out and had some minor bowl work. Rockers are Comp Pro Magnums, Edelbrock Performer RPM intake, gasket matched . The Comp Cam XE282 S solid FT, Smith Bros. push rods.
The cam was from Dwayne Porter and specked for the 3.23 gear and original RR torque converter.
I chose a Quick fuel 780 SS carb with vac. secondaries .
I also took with me my Race Demon RS 1050 carb to test.
I calculated 10.73 -1 compression and ran the test on pump gas.
I really wasn't sure what to expect for output, and I think it did pretty well.
What would be decent HP and torque numbers for this mild build ?
I will post the results later.
Thanks,
Mark
