So I saw you were planning on 10.75 compression, in that case I would not be afraid to run an ultradyne NR71 either.
NR 71
.020 .050 w1.5
284 255 .652
Basically I think anything from high 240s to mid 250s @.050 (depending on actual compression ratio), straight pattern, 108 ls and .620-.650 lift with 1.5s. That's my thinking,for whatever the hell that's worth lol.
