So I own a 1981 mercury Capri. Has a esslinger 2.3l svo aluminum block and head. Blocks bored to .035 over all forged esslinger internals, single .510 lift crower cam. 90mm precision turbo on a Holley 750 double pumper blow through and jetted running 15lbs of boost. Putting out about 550whp. But all this just isn't enough top end speed even with some serious tuning. So the question I've been kicking around is will the entire top half of a s550 2.3l ecoboost fit on my 2.3l svo block and work with minor modifications. To me It looks like ford just made there own version of the volvo Dohc head without the need for drilling and boring coolant and oil valleys. Is this what it is or am I letting appearances fool me? Im just curious because I had a buddy pull his 2.3l and drop the new 5.0 coyote in his s550 and can get his old ecoboost for $500. Thanks for any help in advance.
