Engine Combo

"318 from a 69 Dart, bored .020 over, with R & R'd 360 heads, Edelbrock aluminum 4bbl intake, Edelbrock 750cfm Performer 4bbl carb. Unfortunately stock headers for now. A/C delete and fan delete"

A 69' 318 should have had around 9:1 CR with the factory heads...so that'll be hard to guesstimate what your new CR will be with bigger chamber heads and possible valve reliefed pistons.

I would say get some 302' casting 318 heads, and a XE268 cam, a Edelbrock Performer spread bore intake, and a Holley 650 Spread Bore carb,.....I assume you are running an Electric Fan, so you theoretically would have around 275-290 hp at the back wheels....and it would feel down right "Peppy" for a 318....otherwise if you stick with your current "combo" I think it might run, but it would be disappointing....like 200-230 rear wheel horsepower.
