I have a set of lifters here from a motor that was never run before they were removed and changed to solids.
i'll throw them in with the standard cam.
I have used second hand lifters before in efi holden v8's when given a quick freshen up rings bearings etc and mixed them up and never had any fail but they were using stock cams .
Not that i would recommend it to anyone.
I do remember reading somewhere that some of the original lifters were better quality hardened or coated maybe.
Lifter failure
Re: Lifter failure
I am thinking about advancing the cam it is coming back out soon anyway so it is just to try but i notice the rollmaster has A and R and The dot only 3 keyway notches A R . and i couldn't find any info if any relating to the holden v8.
I am assuming To advance the cam i line the A notch Up on the keyway then use the a outer mark A and use it as the 9 link reference point and it is advanced But by how much anyone know or have a spec sheet i don't have one and the romac site wasn't much help with holden v8's it didn't even mention the 9 link dot to dot.

Re: Lifter failure
I fitted a crow cams chain and sprockets not long ago and it had small sprocket marked as 2 4 6 8 deg + and - with a slot for each from memory .
If you use a dial guage you should be able to work how much advance it gives .
Also with that pin that is a bit to long , are you sure the cam is out of inj motor and not an old carby one ?

Re: Lifter failure
hahaha good point the carby cams have the inlet and exhaust lobes all out of order, youll soon know when it doesnt start or blows your intake off
Re: Lifter failure
Yes it was out of an injected 5 litre but i never had the motor running it was one i pulled down so to check i compared the lobes to the crane cam and they all appear to be in the same spot just a tad shorter lol all except for one ofcourse.Maybe it was used in an early block with efi heads to run the fuel pump who knows i took the cam out and ground the locator down so all good to go now .
It is funny the rollmaster or romac site shows the sprockets the same as the crane package 2 4 6 8 degree offsets but the one i have only has 3 standard advance and retard.

Re: Lifter failure
compare the distance between the keyway notches with the diagrams that show the 2 4 6 8 etc you should be able to get a fair idea of how much advanced it is from that.
No matter what the question is, the answer is always more horsepower!

Re: Lifter failure
Looks like it's about 2 degrees i did ring around and get conflicting info but it seems 2-3 degrees is correct.
Re: Lifter failure
All good back together and running fine I used that ultra black on the inlet either end instead of rubbers or cork and it seems to have done the job nicely no oil leaking or weeping so far.
I used the standard 12p v8 base tune it was way too lean but richened it up and all seems fine so far i think i need to play with the timing though.

Re: Lifter failure
yeah as soon as you put a decent exhaust system on a 304 the standard tune is too lean, you need the 185 VE table, its richer accross the board.
