I ditto Tod,too.No sense in starting a motor until AFTER you set the valves

SST4530 03-15-2008 03:34 PM

With all the issues he's been having, I wonder if he's in fact getting hyd. lifters. Solid, or Rhodes type maybe? :?:

bbc28racing 03-15-2008 06:28 PM

there lunati hyd. and you have to set big blocks on 0 valve lash.and my rocker arms and nuts were bad.

:roll: Dude, Hyd lifters do not not set at zero lash. Doesn't matter if your nuts and rockers were bad or not.

But good luck with that!

This has been a very .....interesting thread.

Maybe he was trying to hold the valves open to bleed off compression to combat detonation.... :P

maxpower671 03-18-2008 08:28 PM

stinky
 
heard detonation is a bad thing? man, this thread has been a stinker..

bbc28racing 03-19-2008 07:40 AM

remember,this is a big block.you cannot turn them a quarter or half round like a small block.the motor will detonate!!

I think you are trolling....no offense.

bbc28racing 03-19-2008 11:47 AM

no,i'm not trolling.i think it's the other way around....no offence And i had great luck with setting the valve lash on 0.

performanceengin 03-19-2008 12:24 PM

for any hydrolic lifter to function properly they need .040 preload on plunger. that is where 1/2 to 3/4 turn comes in to play.

bbc28racing 03-19-2008 12:45 PM

if it's stock it will work.or on a small block.just ask a big block company.or ect.like brodix,or dart(there also small block)or some big machine shops.on a big block the lifters build up more when you rev them up,so if there 1/4 or 1/2 turn it will be like 1 1/2 or something when racing.also roller rockers and poly locks or hex locks are important.

bbc28racing 03-20-2008 09:59 AM

um,??problem?the cam,rockers and nuts were bad and the rockers were kicking sideways which made the push rods freeze the lifters(aslo bad dist.).runs great so far.thanks for help

gimmemud 03-20-2008 10:06 AM

Bet your parts supplier LOVES you.$$$$$$$$$$$$$ 8)

bbc28racing 03-20-2008 02:36 PM

all i bought new was the cam and lifters(on this subject),but that was enough.got the rest from racing shops,and ect.always good to have friends

suicidebomb 03-20-2008 07:11 PM

Speechless
 
Amazing :shock:

Tod74 03-21-2008 12:17 AM

I say the control arm bushings are probably what caused all this....if you are gona run a Ratt you have to have big block control arm bushings.

suicidebomb 03-21-2008 02:34 AM

RE; bad cam
 
Yep....And you*ll need a billingham-langston ganglia wrench in order to install those new bushings! Don*t forget the philpott extension, and those bushings, will need to be milled .025 over-all more than any other place.

itsabird 03-21-2008 05:20 AM

then you have to magnaflux the whole deal.

lively 03-21-2008 09:23 AM

AND WE ALLLLLLLLLLLL NEED A SHRINK!!!!!!!!!! :lol: :lol: :lol:

crazyone 03-23-2008 02:11 AM

bad cam
 
if you have the cam out--check to see if one of the bushings isn't lined up with the oil passage in the block---or something in the passage could be restricting the flow--it has happened on a freshly hot tanked block --it just wasn't flushed out real good

zipper06 03-24-2008 11:51 PM

Doesn't matter, B/BLK,S/BLK the lifters are the same size, there's .100 travel in the piston on the lifters. The only difference is if you have 3/8" studs or 7/16" studs. 3/8 1 turn equels .050, 7/16X20 equels 1 1/4 turns. Set it in the middle and go from there. But it really sounds like you have an oiling problem.

Can't belive I just read all them posts. I would like to add some info but this thread is far two technical for me.

A hydraulic lifter whether in small or big block chevy adjusts the same. zero plus ½ to 1 turn. Anywhere close will work but may not perform as it could.
Now I think the pushrods are too long causing the plunger to bottom out siezing the springs. :lol:

Its not really all that technical, the billingham-langston ganglia wrench is quite easy to master, its the philpott extension that complicates things. :)

lively 03-25-2008 06:10 AM

THAT IS VERY TRUE 8) 8) --ESPECILLY THE LEFT HANDED ONE!!

cepx111 03-25-2008 07:27 AM

This thread needs to be deleted, its not helping anybody at this point. this person was asking for help and obviously needs help. It is the object of this forum to help indivuials that are in need wether they know what they are talking about or not.

True, but heckling him and poking fun at his ignorance doesn't make it a productive thread.....

There is plenty of room for humoring and joking around in " In the pits" section of this forum without offending anyone's intelligence. Again JMO

Jeeeminy Charles, have you read this whole thing? This thing stopped being productive 4 or 5 pages ago! We all tried to help the guy, no ones even mentioned ignorance till now! If i insulted your intelligence I truly apologize, but you need to lighten up. Most of us take our humor, where we can find it! The guy says he has a shop(business?), if so then he knows how to adjust hydraulic lifters, if not, he needs to find a new line work! JMO, I think he was trolling for aggravation, and caught his limit. Let me add, that that he also knows his lifters aren*t oiling, And it ain*t because of his distributer, wiring, heads, or a bad cam. I*M more than happy to apologize to anyone I offended, but I*LL be go to He@^ if I*LL delete it!

olds48 03-25-2008 02:41 PM

I'm with Charles.Guy might not agree with us,but it's not our place to ridicule him.Starting to go too far now.Time to grow up.
