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

 

Not enough info there...need to know at least max lift, this you can measure by riging a dial indicator on a retainer while rotaoing the motor be hand. This has to be doen on both intake and exhaust valve
