hey

 

i was just viewing some of the old threads..one was about having your cam reground, i don't understand that concept fully..wont they work in reverse, taking metal away from your cam ?

 

also do u need any other modifications if u have your cam reground ??

If you want to increase the lift of the cam, you grind away the back (smaller) side of the cam. As you adjust your tappets on this side, it will follow a larger lobe, thereby increaseing lift. You're not regrinding the whole cam, just re-profiling it.

aah ok..sounds simple enough

 

so any new parts gotta go in or can u keep the rest of the motor stock..mine will have a 3k head,possibly port and polish not sure yet though, money will be the issue

no worries then..

 

2 inch through..3k head, reground cam = ???? kw extra

yo jamie me man, in ur site u said ' heavy duty single springs', ...can u tell me which model it taken from or what brand???? 7500rpm not bad

Don't think you need heavy duty springs. I have had no trouble with stockers revving out to 7500+rpm.

stock springs will hit 8 grand no worries, but do it enough (racing, or just because you like seeing the tacho hit 8500rpm, like me :)) then the springs will wear out. i suggest heavy duty springs unless you like changing valve springs every couple of years

 

i don't know what my springs are from, or what brand they are, an engine builder put my head together and just found something that fit. but they were only $110 for the set (as opposed to $80 for stock springs)

do holden 202 springs fit straight on ?

 

so reground cam u need... 2icn exhuast, extractors, new lifters, heavy duty springs? '

 

is that all ?

so praticaly i would be able to rev to 8krpm just simply re-ground my cam and install it to my stock 3k head...correct me if I'm wrong.

plus extractors and exhaust system. head porting would greatly help in the quest for 8000rpm

alrite..keep your hat on mate

ahh tom jones. baby take off your shirt... da dada da da, you can leave your hat on! :)

haha if u and Super Jamie like it that way..by all means go ahead
