After loosing my electric water pump and hurting it last year. 270 plus on my closed loop cooling system. It is going back together with a few upgrades. Squared everything back up. Some Dart coatings on the pistons DC2 reflective heat barrier on the domes and DC1 anti friction coating on the skirts. Going with a steel gapless top ring and callico coated bearings. New cam 283/294 at .050. .800/.766 lift on a 115 lsa. Going from a double to a triple valve spring Manley 221448. Compression a little north of 15 to 1. Should be on the dyno next week. Will post a video. Oh, and it will be a simple belt drive pump with lake water cooling this time.
