ArchetypeDatsun Posted June 9, 2012 Share Posted June 9, 2012 (edited) I searched this for about good week and a half and I didn't have any luck. So when coverting my P90a-H (Hydraulic) head to a manual lifter taking the parts from my P79 head I discovered it had an "F" Camshaft. From my understanding after researching about all production years each camshaft that was from each engine the "F" camshaft is almost similar to the "A" camshaft. What I wanted to know if anyone has used the "F" Camshaft with a P90a-H or P90 head on a L28ET and was there any small or big changes in power or rpms? I also wanted to use the "F" camshaft because I already took all the parts from the P79 head the camshaft was from onto the P90a-H head that I'm coverting to manual lifters.

calvin280zxt Posted June 9, 2012 Share Posted June 9, 2012 The F is similar to the B I have in my car (turbo auto late 1981) the f would be a step up from the M (weakest cam) and if the lash pads etc. are off the same head why not. Here's the specs http://atlanticz.ca/zclub/techtips/cam/index.htm Quote Link to comment Share on other sites More sharing options...

letitsnow Posted June 10, 2012 Share Posted June 10, 2012 I noticed a big change in power going from the hydraulic cam to the 'A' cam, but I have to attribute the majority to the fact that the hydraulic adjusters were in very bad shape. The 'A' cam runs great and feels reasonably rev happy for having 7.4:1 compression. There isn't much loss of torque, it made 340ftlbs with the stock turbo. The 'F' is lacking a few degrees on the 'A', but is still a bit of an improvement. Quote Link to comment Share on other sites More sharing options...
ArchetypeDatsun Posted June 10, 2012 Author Share Posted June 10, 2012 That's what I thought I just don't want to run the "M" camshaft since I switched from hydraulic lifters to manual lifters the "F" camshaft seems like a better choice for now.

FricFrac Posted June 10, 2012 Share Posted June 10, 2012 Does anyone have the specs for the "K" grind? Quote Link to comment Share on other sites More sharing options...
