Camshafts: What effect does increased lift have on performance?
Absolutely.
It appears to have been approximately .010 below deck with 5 cc valve reliefs. .020 over, stock 3.58 stroke. I don't know the exact chamber size but online sources show between 63-72 ccs for a '308 head.
The first and worst case scenario comes in at 10.52 to 1, way too high for an iron head engine on 91 octane. If the pistons were .020 below deck, it gets slightly better:
If the heads are closer to 65 ccs AND if I used a piston with an 18 cc dish, the C/R gets around where I'd feel comfortable.
I don't want to always have to run 91 octane with this car:
The Dart has a 4.10 gear SG 8.75 axle. The intake that came with this engine will go back on it.
Buried in that is the RPM Air Gap. I'll also use 1 5/8" headers and 2 1/2" pipes with an H pipe and Flowmaster mufflers.
