Cam Timing Sharing
Over the past year or so Iv'e been attempting to squeeze cam timing information out of reputable tuners and builders so I thought Id'e share..
Muzzy 105/100 broader power band
Muzzy 105/103 latest lobe centers ( I have it now pretty damn good)
Schnitz Racing 105/105
Brock Davidson 104/104
Lees Performance 105/108 (under 190 pounds)
Lees Performance 105/105 ( over 190 pounds)
Go Kart Racing (can't say who) 105/107
Y2KZX12R 102.5/101 or 103/101 (excellent under 9500)
Kawasaki Factory 104/102 works good for box stock applications
Webcams with 383/369 cams 103/105
Thats about all I have please post comments or let me know if I have made any mistakes..

Supra,
it's a generous thing to compile and share info!!
But, optimum cam CL's will vary accoring to engine configuration and intended application.
What's good for my 15.5:1 1427 @ 1/4 mile is prob "not so much" for a 13.5:1 1270 @ RR course.
just an observation...

Compression is the holy grail. Largest single factor in increasing power.

Now all you have to do is to compile a cam timing list for the 1270/1290  with and without the extended ECU
