http://www.modularmustangracing.com/ 351r 5.8L modular engine block $3300:P
MMR stage 2 2v heads flow 227 192 and cost $1399 and fox lake flow 223 195 and cost $1795 -----I think MMR is more of a bargain....:P however mmr has factory valves springs retainers and locks and stock cams (no core charge they use brand new heads!)
Upgrade to MMR stainless Steel swirl polished valves $269.99 Upgrade to Comp high performance springs $239.99
where fox lake has Ferrea oversized valves, Manley hi-rev springs, solid bronze guides, Vit
seals (does not include cams) and they want your core
Dunno whats the better bargain? ?
I know i would do all the upgrades..
