Running Rough Question
It’s a 68 Chevelle with a SB350. QuadraJet carb. It struggles ‘under load’. Starts right up idles smoothly.
1) cylinder 8 header reaches max temp of about 220 degrees all else 500 plus
2) cylinder 8 has compression of 140 vs 150 on all others
I’ve changed plugs, cap, rotor, wires.
I’ve pulled the valve cover and rockers / arms look fine.
im down to the carb.
Any other ideas? Please help so frustrated!
