I also posted over no LT1 forum...sorry if that's a problem.

Broken spring...but lucked out, it hung high. Want to replace all of them ASAP! We don't know what kind they were...single bronze colored plain springs.

Engine:

LT-1 with 12 # vortech on a rebuilt 355 with JE dished pistons about 9.8:1 comp. and a mysterious Lunati Blower cam....we don't know the cam specs only that it's most likely 114 LSA and set up for 120 # valve seat pressure.

Will not plan to rev over 6100 rpm. This is an A4.

Is this enough info for you guys to reccommend the best valve springs for the job? Sure appricate your advice!

Thanks, Ram
