1- would ls6 valve springs work with a .563 lift cam?

2- instead of using the jpr tool to hold the lifters up when the cam is out, would it be possible to use 2 1/4" or 3/8" steel rods? if anyone here has the tool, could you check what the diameter is?

thanks

More than lift should be taken into consideration when picking springs. The lobes/ramp rates used matter as well. I personally would go with some nice comp 918's.

Do some searches and reading on cam swaps. You can buy 5/16" metal rods or simple wooden dowel rods and it works perfectly fine.

all ive heard is about the 918 springs. its just that i can get gm parts at cost, so save a little $$ here and there, then i can put put a little more $$ here and there.

thanks for that # too. 5/16" is what ive been looking for.

1. LS6 springs would not be a good idea on almost any aftermarket cam. Once you start getting more agressive lobes and lifts, you need something like the 918's. I have a 563 lift on my TR 224 and I actually got Comp 921's. It's prolly a little over kill but I wanted the best I could find.

2. Steel rods would be a great alternative to the jrp tool. I used them myself on a cam swap. I wouldn't use wood though, it could splinter. For the few dollars extra, it's not worth taking the chance. I believe they were around 5/16th's of an inch in diameter. Just spin the cam real quick and the lifters should stay outta the way, then you can slide the metal rods in place for insurance.
