valve train?

i picked up someone elses project that needs valve train set is it hard? its a 1977 305 out of a impala new cam lifters and timing chain..got to jegs.com and search for part# 350-2102 or read this.. first off its a 1977 chevrolet impala 305 with this cam and lifters ..performer intake and 600 carb came in kit too

this is all the info i have thanks..

What do you mean, install it, adjust the rockers, re-read your post.

cam and lifters are in it..i need them set. thanks

They are hydraulics or solids.?, still waiting fo all the info here. If hydraulics the std procedure of loosening the rocker till the pushrod can be turned then tightening the rocker till noise just stops, then about another 1/2 to 3/4 turn.

i dont know what came with the package ill try to find out and post back a.s.a.p.. i bought another headach, the guy who put it together decided to take off so i got the car and motor cheap.. and i dont know what came in the intake cam and carb kit..

they are flat tappet hydraulic lifters.. thats what jegs said

Ok, use the info I gave you.

will do thanks alot!!!

Just make sure that when you use the method suggested by maxwedge that the lifter is on the base circle of the cam for the rocker you're adjusting (you'll have to rotate the engine to get it there for different valves) -- if you don't (ie perform the static adjustment when the lifter is on the lobe), when the lifter does find the cam's base circle, there'll be too much clearance, and possibly bent pushrods.

If you don't mind a messy job, get the engine running -- loosen the rockers until they clatter, then turn them down until they quiet, then 1/8 -1/2 turn.

You should install the new lifters after "soaking" (submerge) them in motor oil for 24 hours -- this will make sure they're filled with oil as they would be when they're sitting in the engine, and they'll have their normal set. If you don't do this, your initial setting will likely be well off initially, and change as the lifters become pressure-filled by running in the engine -- sometimes this can take a while, but when they finally get their fill of oil, you may notice a distinct lack of power because the pumped-up lifters will be holding the valves off of their seats -- in the intake valves this will certainly cause a backfire through the carb among other bad things, so pay close attention.

so adjust them when lifter is on top of lobe?

No.

When the lifter is on any part of the lobe, the valve is gonna be opening/closing (not what you want) -- what you're trying to do is adjust the rockers when both valves for the cylinder you're adjusting is closed. You can't adjust the lash on any cam regardless of lifter design (solid, hydraulic...) when the valve is open, it needs to be seated.

You can't "see" where the lifter is once everything is assembled, but if you know the engine firing order (which you must) you can rotate the engine until each cylinder is on the compresion stroke (both valves closed) and adjust each cylinder (there are also tricks to do several at a time between rotations, you'll have to read up on that one, but ALL small block Chevrolets have the same procedure). Removing all the spark plugs from the engine will help you both turn the engine by hand, and indicate the compression stroke for the cylinders (air will rush out the plug hole whenever the piston is rising in the bore).

Should be done running to make sure the lifters are pumped up, if you do this engine not running it must be done with each valve fully closed, then leave some looseness in the rocker for the lifter to pump up, this will prevent over tightening the valves and possibly holding them open. After the initial set start it and go over the valves one at a time, let it run long enough to make sure all the lifters are pumped.

thank you maxwedge and sinnercee
