thanks for all your input guys. and thanks for the list of parts brad70. im just looking for alot of parts in general. just so i know alot is out there. i was looking at stroker kits, chryco, why did you chose the 512 over the others like the 528, 543, and the 572?
We have built 23 engines using the 440 source parts , no issue as long as your machinist checks everything over , the pistons, rings & brgs are all top quality parts , the cranks & rods are made by 440 source , I would not base the quality of the parts on the replacement water pump housings .
The reason I generally choose the 512 combo is it retains most of the rod ratio while removing 7lbs from the rotating mass , more CI doesn`t nessisarily increase the power& it will reduce the rod ratio , & push the oil ring up into the piston pin & creates more of a short life race engine than longer life street performer but still has massive torque .
the 906 heads can be used as well as the headers designed for a 440 But I would not recommend it even extremely ported the flow #s on 906 heads would limit the power , even more os with the bigger 543 over the smaller 512 " build , if you go to a better head usually the exhaust ports are raised which causes problems with header fitment ,usually this requires special headers to match the heads
