what would make cams effective crame has some for the 3.4 but what else would i need if anything to make it effitive....

 

You might want to try the Advanced Tech section.

 

when i got mine i was advised to get stiffer valve springs. thats all i was advised to get.

 

first i think knowing exactly what a cam does is needed, it opens(lifts) your intake and exhaust valves and holds them open (duriation) in a way that it will allow the incoming air to enter the CC, then close the valves to allow the gasses to compress(unless its a miller cycle engine(yours isnt)) then it opens the exhaust valves and lets the exhaust gasses excape, and then starts over again

with that said---

the differences in the stock cam and an aftermarket one can be huge, however, i have done quite a bit of research on what the specs are for the stock 3.4L cam, and my results, NO ONE KNOWS FOR SURE. so who knows if the aftermarket cam's provide more lift or duriation....... see what im getting at

but back to your question , what will it take for the cam to be effective - well theoretically nothing, as long as your valve springs arent reallt worn they should be fine, but new ones will certainly help, also you might consider a new rocker arms with a higher ratio(1.6) and while you are at it a new set of pushrods wont hurt either, most of the people i know that have replaced the whole valve train at once have been very happy with the results(none of which were running a 3.4L though).

and Teal , I WANT TO RUN YOU!

 

come to my town and we'll run em!!!

 

As far as running the cam in the bigger engine, there are people that have run over .500'' of lift on there stock heads.
Before you get a new cam you have to know whats in there, I don't rember the numbers but the stock cam has good lift and crappy duration some thing around 196' on intake and exhaust and around .450'' lift.
I have had these engines out of cars and it is a pain in the *** to change the cam I have herd of it being done with the engine still in the car but the people that did it had to take out the A/C condencer and radiator.
If I put a new cam in my 91' 3.1L I'm pulling the engine, but I also have ported heads and and ported exhaust manifolds to stick on the engine.
I'll tel you about the stock cam, it was made for a 2.8L to get good gas milage and low end power and the engine dates back to 1978 when it was orginaly designed (befor they put it any thing) for little cars and little toy trucks and it hasn't changed a hole lot as far a power it makes.

 

yea i saw in summit that cran cams have ones for 2.8 3.1 3.4 ill write the numbers down!!!
duration @.050 gross lift
intake exhaust intake exhaust
rpm range 1000 to 4000 198 204 . 401 .423
1500 4500 204 214 .423 .423

 

stock cam is weak, stock heads are pos.

keep that in mind. to go to a real cam u will need heads too.

real cam + stock heads= LOSS of power.

 

Don't get the crane 2030 CAM. I did the CAM and rockers and although it yielded some gain it was not what I expected. Since the time I did mine others have come out. Look at www.firebirdv6.com in their forum section and do a search. Go with a custom grind, new springs, and rockers
