Tho I'm a firm believer in k.i.s.s. & checking TDC & a basic compression test is always a good idea I'm gonna go out on a limb & opinionate that the long block is healthy & that includes the cam timing & that the the prob is: ECU going bad, plug wire order wrong, VACUUM LEAK, rotor phasing



I just did a compression test and all 8 cylinders are darned near then same readings. I rechecked the wires and they're right. Is there any way to test an ECU? And if I measure the lifters' preload what should the range be?
