I think I would go with the cam card (.644) more than the hand writing on the box. Have you checked with thunder racing to see its a shelf cam? If its a custom grind I would call them and give them the serial number and see if they can provide you with the info you need. Plus you could always ask for Nick.....

Well it suppose to be the TRak cam. The number that dosnt match trak cam specs is written in pen. Unless its a custom trak cam.

I read it as: 232.7(.644")/235.16(.595") 112lsa which is the cam doctor specs.


You got the correct cam and the specs are within 1%, their rarely spot-on.

Awesome thank you for clearing that up for me. Guess he just wrote the wrong lift down. Witch sucks because i just sold my hand ported 853 heads with dual gold springs assembled -_-

Guess ill just get some 243s or 799s and some new dual springs. Any suggestions?

Yeah, looks like he wrote the valve lifts in the wrong spaces to me.

would the 243s be a good inexpensive head to go with you think? not a whole lot of cash to spend. i have a broken header bolt inside my heads and they are parameter bolt heads as well so i wanna just ditch them completely.

also would i benefit from getting a .675" lift rated spring vs a .650" lift spring?

243s would be good, as far as springs Id go with at least .675" lift springs.
