K cool i made ,mine from my old set of extractors have you thought about that.

What you talking about now casey

Sounds good the bellhousing too me,ill check it out. Yeah theres a difference between tell it how it is and "tell it how he says it is".

So what are you saying is wrong with the regulator,the manifold vacuum at idle opens the reg to reduce the pressure at idle and then when vacuum drops it increases again.

Ill do one soon for ya mate :o

Hey you like that shit don't ya!!!!!!!!!!!!!!!!

Ok found it Ridgecrest Engineering 18 collins Road, Dromana Vic 3936 Phone 03 59 814334 Fax 0359 814337

Yeah ran 13.7 @103. Got a few issues to sort out,but was happy with that with first run on about 16 PSi as clutch wouldn't hold anymore than that and gearing is all wrong for any bigger MPH at this stage. Just make sure its on a DD dyno mate or you might get flamed. Heres a few pics from wed night,hope you don't mind.

What you hopin for Si

Ill check for you when i get home

thats exactly what i have 5K dish pistons,3K head with copper head gasket and shim and it comes out at 7. 8/ 1

As title suggests is anybody keen for a drag this wednesday.

By the BUMOMETER i mean has the seat of your pants feeling changed ,does it have more grunt. Gearboxes are ok but ive stripped the teeth of one just the other day so ive backed of the tune down low to save it I HOPE till i can do the K-T bit.

Geez that is looking very tidy i must say Si,i beeter get to and tidy my lot up ey,how does it feel with the new setup,Mate grab and efi setup ASAP you wont look back,its a bit more cost but the tuning capabilities are endless mate as you well know. Does the bumometer tell a good story and how much boost you running,also where did you get the oil cooler adapter from. Keep up the good work. Matt

This sounds like a plan to me,can you check how much preload is on the existing lifters by checking how many turns it takes to loosen the rocker gear,this will tell you how much preload you have . Normally on a UNC threaded bolt it is from 1/2 turn to a 1 1/2 turns that is the limit of the lifter internal travel and 1/2 makes sure it is running in the normal lifter range to avoid tappet noise. So if you back of the rocker gear until the pushrods are just contacting the rocker and then tighten it down again on say no1 cylinder with no4 rocking you will see how many turns it is until the pedestal contacts the head.

I did wonder where you had got too. Anyway welcome back,keep it clean :P Matt

Doug,everything you said was very true,and the part about checking the basics is the FUNDAMENTAL step that most "professionals" fail to do most of the time. I'm with you maybe there are lifter ,spring coilbind,rocker geometry issues that were ,are being overlooked right from the start. This is very uncommon as you are aware and there is a story to be told by what has happened. No offence taken whatsoever,constructive critisicm is how we evolve to be better at what we do. Matt

Felix Here is something to think about. As i have been an engine reconditioner for 25 years i understand lifter preload and base circle diameter very well, and i also understand the point you are making that if the replacement cam has a larger base circle than the failed "reground" cam then yes the lifter internal working area could be compromised and hold the valve open. On the other hand the point i was trying to make is that history shows that hydro and solid cams do not normally have the same opening and closing ramps ,hence why they use two different cam followers. In this case it would appear that to be the case going by the information supplied to us by CAM. A "normal " lifter has a working range of around .120" and whether or not the whole base circle thing was explained to CAM by whoever he got advice from regarding the changeover who knows ,it would appear that there needs to be some insight into the what exactly has been put into this engine both the failed cam and the replacement item Matt

I think it is fine when you run solid lifters ona hydro cam cause there is no way it can pump up the lifter BUT when you run hydros ona solid what happens is the opening ramp that would normally soften the opening ie: remove the tappet clearance lash and make for a nice opening actually "TAPS" the bottom of the hydro lifter causing it to lift then drop then lift again inturn causing a tiny bit of oil to be pumped into the lifter hence "PUMPING" it up ever so slightly and after a number of these it will eventually hold the valve of its seat depending on the spring tension. That my take on it.

I spoke to cam today and it would appear that the 4/5K cams are the same part number thanks to Trd so he has decided to run it and see how it goes. All the best mate.

Yes is this correct,do not put a solid grind 4K cam into an engine that is setup for hydraulics it wont work.

Ok thats looking good Si, i need to setup my fuel sytem with a purge tank someday and mount the fuel pump :P . Looks great mate keep up the good work. 125Kw's here we come ey.

NOOOOOOOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!! Stick with the re-ground cam mate.we will work through it with you.Do you have a manual or do you want me to emaiol you the pictures. Ring me if you want,PM me and ill give you my number. MAtt

Might as well use drinking straws if youre gonna use WILDCAT, I have a brand new set of pacies but you wouldn't want to spend how much i want for them.

Cameron stop frigging around and check the cam timing mate. :)
