fjh Posted July 14, 2022 Share Posted July 14, 2022 15 hours ago, Joey Mack said: as far as lifter's.. its just my opinion.. I really dont have a good answer.. I just like steel over ceramic, but I have seen ceramic run for a long time. the one I am currently building is 11 years old and the ceramic lifters did not fail.. truth is, with ceramic lifters, I dont like loading the cam in the block, in chassis. I would rather have it on a rotating stand so i can tip it upside down.. i think using the other VIN is a good idea.. make sure you know what cam key is used. it may be straight but ,,, be sure... white side out for the 427/460hp.. if its offset.. jojo I agree I hate doing these in frame too easy to drop a lifter easy to make a mistake ! If you accidently drop or smack one with a cam lobe is it any good?? The ceramic seemed to solve the etching issue how ever who really knows what the real problem was with the steel they worked well in some engines and not others! know one ever clarified why they were failing!

I like free shipping.. go with steel lifters. $100.00 each... jojo These parts from ATL are PAI brand? Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted July 14, 2022 Share Posted July 14, 2022 yes, RED.. I just recieved my second set of kits today.... PAI... jojo as far as to why the steel lifters failed, what I was told was that the soft brass axle for the roller gets a flat spot, then the roller stops turning and digs into the cam.. I can explain the ones where the 'case hardening' flakes off.. maybe thats from poor maintainance. jojo Quote Link to comment Share on other sites More sharing options...
R.E.D Posted July 14, 2022 Author Share Posted July 14, 2022 Ok sounds good..I'm looking through the camshaft bulletin posted on another thread and trying to figure out which is the Ac cam I need.my truck does not have an engine brake.

R.E.D Posted July 14, 2022 Author Share Posted July 14, 2022 I'm guessing it's one of these two. Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted July 14, 2022 Share Posted July 14, 2022 on the end of your cam shaft will be the Mack number.. My suggestion, is to pull the front cover and look.. jojo Quote Link to comment Share on other sites More sharing options...

R.E.D Posted July 14, 2022 Author Share Posted July 14, 2022 Please excuse my nagging.just want to be sure I'm installing the cam that will work.i know this is a experimental procedure that should make an improvement and that I'm taking a risk ,But last thing I want is to put everything back together and it doesn't work right.I can't spare to be down a truck.im barely handling my work load ..lol.

R.E.D Posted July 23, 2022 Author Share Posted July 23, 2022 (edited) What is the best way to do a valve lash after cam install?how can I tell that # 1 is at TDC compression?and not #6? I was told that It was done by lining the timing marks on crank ,cam , and idler but I don't trust it.i know that all those 3 gears line up in time every 16 revolutions therefore I wonder how it's done.Thanks in advance.

Joey Mack Posted July 23, 2022 Share Posted July 23, 2022 easy breezy.... barr the engine around to 1&6... then, look at the #2 exh. rocker arm (the front one)... exh. valves are to the front of the cylinders... it should be 'rocked' opening the exh. valve. that means you are up on #1.. if #2 exh. rocker is not rocked, then you are up on #6.... jojo 1 Quote Link to comment Share on other sites More sharing options...

Red Is your engine equipped with Jacobs or Dynatard or nothing? you need to cross reference like engine configurations to get the right part !What your doing will work however you are worried about the right things here! That said the exhaust manifold thing is much less intrusive ! but if your doing a cam anyway..............! I get it! and in my opinion you should convert the exhaust to 5 inch as well! Put your cards on the table it will be easier to help if we can! Edited July 23, 2022 by fjh Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted July 23, 2022 Share Posted July 23, 2022 good question 'F'... i read back a few posts, and I believe he has an ASET-C without an engine brake.. But I'm not so sure... I expect it to have a powerleash.. I dont think I ever worked on an ASET that didnt have an engine brake,,, if he has powerleash, we need to clarify the proper valve adjust steps,,, ceramic lifters dont like an incorrect adjustment.. jojo Quote Link to comment Share on other sites More sharing options...

Note also when your setting besure if your engine does not have a guide pin on the intake valves that the cross head is seated correctly One of the boys from work called me yesterday and said he had done a cam job the week before and it came back a week later ticking! He found a bad set on one intake I questioned him on the yoke pin He said nope no pin I said re set it ! I think you'll be fine now! Just something to watch for!

Joey Mack Posted July 23, 2022 Share Posted July 23, 2022 I have small pairs of feeler gauges that I took out of sets, and riveted them together. I have different pairs for different engines.. which also means I have full feeler gauge sets that are missing several individual gauges...

Thanks !clarity is good! I believe these AC were offered with jake or power leash! if he receives a power leash cam and doesn't use it it will likely be fine ! If he receives a power leash cam and has a Jake! different story me thinks! Just sayin! Edited July 24, 2022 by fjh Quote Link to comment Share on other sites More sharing options...
