LSX engine compared to Pontiac Iron..
LSX= Cheaper, lighter, more fuel efficient, more reliable, longer living, much better design, more performance choices.
Pontiac= torque, under hood appeal, classic exhaust note.
L98 heads flow I believe 310 cfm out of the box and a set costs half of one out of the box aluminum Pontiac head that flows much less. Just one little example..
Flame away.
