I didn't quite know how to measure pushrod length with hydraulic lifters since they would collapse without oil in them. I don't have the pan on so I can't pump them up either. I read my options were either buy a solid lifter and do the measurements with that or buy a weak set of springs that won't compress the lifter. I'd rather not disassemble the head if I don't have to so I'm trying to find a solid lifter with the same dimensions as my hydraulic lifter.
I have this lifter https://www.lunatipower.com/Product.aspx?id=760&gid=208 and other chevy lifters have the same 0.842" diameter but none seem to have the same seat height. I'm not sure what "seat height" is referring to for a lifter? but just need a solid version of my hydraulic lifter to check my pushrod length. Any ideas? If not, I'm going to call Lunati in the next couple days to see what they think the best course of action is.
I can also install the oil pan temporarily and prime the engine to check the length. I could also prime a lifter before I put it in (I'm not sure if the oil would actually stay in there during the check and give me messed up measurements.
Other than that, I've been doing a lot of bodywork since I've been back at school. Should be looking at buying a SPA manifold and larger valve cover (I'm assuming the stock one won't fit over roller rockers) in the near future. Turbo and carb/EFI setup soon to follow.
