Re: Lifter swop

The later 4v heads have small valves? With the big ports? And open chambers? That doesn't sound very desirable. Are you replacing bad valves? Optimally, if the heads are off check out the guides and seats for wear. If there is erosion on the seats or looseness to the guides you ought to have the hea...

Re: Lifter swop

2v and 4v valves are different diameters. They cannot be swapped. Are you talking about rockers?

Re: 1969 351w 2v Fex Plate weight?

The AOD flexplate is the same as the FMX. If your FMX plate is good there is no need to change it. Swapping from C-4 and C-6 will need to change the flexplate due to diameter or offset differences.

Re: '69 A/C Help Needed

Stock is an expansion valve. I need a refresher on A/C myself, but I wonder if the valve is not opening when it gets very cold if that could promote excess high side pressure. Thinking outloud here: Or, do you think it's possible you overfilled the charge?-----but then the lowside might read high to...

Re: A real head scratcher

Like Royce mentioned 1. No spark or spark at the wrong time.

To have a couple cylinders not firing, perhaps the plug wires for cylinders 3 and 8 are swapped?

Re: Small block C6 questions

You can use either Type F or Dexron/Mercon 3 in the C-6. I'd look for the correct dipstick tube and stick. It's possible this GM stick is the right length, but to find out, you'd have to remove the tube from the car. Put the stick in the tube and note where the crosshatch area is on the stick in rel...
