I have purchased a roller cam kit from a T.R. owner in my area & on installation, my machinist informed me that @ the proper installed valve spring height, the springs are @ 100# seated pressure. As far as I know hyd. rollers should be @ 140.
To shim these to the proper pressure I will be into coil bind.
Is anybody else here using such a low spring pressure on a turbo motor.
It is a crane cam & calls for 99838 springs. Cam is PN-81hr00003
I think that these springs were ordered wrong, & are for a non turbo motor.
I am not new to turbo buick motors, just looking for some other feedback to offer to the seller.
Thanks, James
