Does any one have any experince with these springs? I will be a bolt on platform for a while but will get a cam probably nothing too radiacal. I want for now because I have 1.6 RR's and dont want to chance the springs anymore.

an LT4 spring sounds like an Ideal "for now" solution

Is there any thing wrong for running these springs with a cam? I'd rather not do it twice.

david from thunder racing said this about the 99893 springs (that come in the 10308-1 kit)

"These can be setup very tight for cams up to .650 lift and are good for 7000-7200rpms"

Would these exert too much pressure on stock lifters causing them to colapse?

I just bought a set. I thought they were only good to .600 lift.? Friend on mine has them in his 94 Z with a Comp Cam .540 lift range?? and has gone 10.9 @122 with the stock lifters.

Stock springs are fine with 1.6 rockers. Get the Crane kit any way so you will have it for your new cam. I got locaters and more shims to make sure installed height was correct. Smaller valve seals are required. No problems with XE cam and stock lifters.

I had the Crane 10308-1 springs in my old 94 Z28...i loved them with my 224/230XE cam....made the car rev a little quicker...they are a great bargain and very reliable .600 lift spring that will fit stock seats for $150 or so...also they give you the extra assurance of dual valve springs..i vote for getting them
