3.4L Cam and Underdrive Pulley?
#2
caleb just did it so he can answer better on time frame of cam install, underdrive pulleys don't do much since they make the alternator less efficient, and they only free up about 5 hp (around 10% is the claim) your also going to have less coolant flow
#3
they make underdrive pulleys that include the alt/crank/water and kits that only include the alt/crank
thing is with underdrive kits like March for example (i have one i know) the alt underdrive is the same size as the one you get from kragen, the crank is undersized tho, donno bought the water one, didnt get it cuz of the coolant thing arch is talkin about and i always wanted to switch over to an elec water pump.

as far as the gain...not too noticeable, but top end was improved. however this all depends on the cam. mine was only .469/.469 gross lift and 260 advertised duration.

Anyways the only think I don’t know how to do is to adjust the heads valves so that the only thing that stoping me form geting a cam.(my cousin help me with that when i change the gaskets but he is not here anymore)
BTW does the sound change alot?

its easy. comp describes it in their manual when you buy the cam, and most others will too. just rotate the crank until the exhaust valve begins to open. then adjust the intake valve. when theres zero lash (the pushrods stops moving) tighten the rocker nut another 1/2 turn. that intake valve is done. then rotate the crank some more until the intake valve goes up and back down, now you can adjust the exhaust valve. do the same as with the other valve.

geez jes. you dont have any idea what youre talking about do you? if youre gonna explain it, explain it right. yes, its 120 degrees, but the firing order on our engines is 1-2-3-4-5-6 so its not #6 when you do #1.
and it is best to do it my way...that way the valve is on its base circle. when you do it at TDC theyre both closed, but not the furthest from open.
