Not sure what mine makes, probably about 350-375hp, but its a VERY simple engine combo.

'77 360 with stock pistons
Magnum Heads with R/T Springs & Retainers
Summit K6901 camshaft (218/228 with .441/.441 lift (.470/.470 with the 1.6 rockers)
1 5/8" headers
Edelbrock Air Gap intake (Magnum type)
600 Holley.

This thing runs strong!!
