NewZed Posted October 4, 2011 Share Posted October 4, 2011 This might be too vanilla for Hybridz, but it seems more likely that someone here has tried it and would know. I'm wondering if the ECU/AFM EFI system for an N42/N42 block/head/A cam combo will have problems handling an F54/P79 block/head/F cam combo (the NA setup with flat tops). The CR changes from 8.3 to 8.8, and the cam grind changes also. The N42/N47 A cam has more intake lift and duration than the F54/P79 F cam, along with altered opening and closing events. I'm using the AtlanticZ page for reference on the cams - http://atlanticz.ca/zclub/techtips/cam/index.htm I might pick up a spare ZX engine for a spare and would use the stock 76 EFI ECU and AFM to run it in the future. Not "looking for an easy 400 RWHP at 9000 RPM" stuff but if anyone has comments, feel free... Quote Link to comment Share on other sites More sharing options...
