do a search about quaddies they handle heaps. whats the specs of the cam, what gearbox & diff, what intake manifold do you have?, how driveable do you want it?

yep. you need to know whats inside your engine before you can push it further.

i.e. i have NFI what a "stage 3 head" is. what cfm does it flow at what lift?

lol i have no idea either dude thats just wat i got, told an from talking to him thats wat he got told lol i got a vl cailas diff in my vc that im thinking ill take out to put in it, not sure bout the manifold, how do i tell wat sort it is would it be written on it?? i want it to be a daily sort of i only live bout three km from work so fuel spendage is not much of an issue lol how can i tell if the heads have been worked?? is the only way to take it all apart an get it tested??? the trans is just a trmatic 3 speed, should i change that or just shift kit an stally it??

Compression and vacuum test is a good place to start to see what condition the present motor is in.

You may be better off doing an injection conversion on your 5L
drop the donk out do rings, bearings,timing chain & EFI cam, bolt on EFI heads & bananna injection manifold. At least you will know what it will have in it and eith EFI it will go alot better too.

You can also pick a suitable cam for the engine tot he heads you buy, just depends on your budget.

if you havent got any money dont fiddle with it, give it a good service like you said and leave it at that
plugs, leads, rotor button & cap, fuel, air &oil filters set the timing and just drive it.
