Fair enough but it's more than 5hp.... I've got at least 12whp more in my bored m52 (11.5:1 86.5mm pistons, with s52 cams, m50 intake manifold, pulleys) than an s52 with similar bolt-ons... And the s52 still has more displacement... The other advantage is the crazy amounts of torque.

Anyways I'm not criticizing, just offering my $0.02. Should be a good thread as is!
