Okay so this is it folks the real deal this is the thread and I've made up my mind. My plan is to make a Hydraulic roller valve train motor.

The build is going to be based of this article- http://www.gmhightechperformance.co...raulic_roller_valvetrain_install/viewall.html

I have not decided on a engine builder yet but I want either Ajax Engines, Nash Engines, or Roger Tennanet. Dose anyone have the Turbo Buick engine build specs, Clearance for the barring's and what not? I want to do this once and only once at least for a few years. I will be adding progress and questions as I go. The biggest question is when to start because i want to make the next few meets but I think a cam lobe is whipped because no mater what tuning I do or what I do I get knock at high rpm and it falls flat due to the valve springs.

This project will not be skimped on and I'm not a quitter so this should be a fun first engine build.... although I didn't want to do it so soon I guess I have to.

Have you measured the lobe(s) to check for suspected wear?

I haven't done anything yet so this project might be easy or hard as the farther I get into the motor. Up until this point I've enjoyed a underpowered Turbo Buick and complained along the way haha. I just know it in my Gut that something internally is out of wack.

I'm leaning more towards Ajax engines. I believe they have done a few Turbo Buick motors in there day. No matter who you bring your engine too its a scary ordeal. All your hard money and work just to turn the key and find out it was built like a Chevy and you have no oil pressure..

I also saw that AJAX motor for sale on Kijiji., if I remember it was all studded and a roller for $5500. I thought that was a good deal.

I trust you will do this on another motor, things won't go as smoothly as you planned
and two years later your dad will make you sell the roller hogging the driveway.

Very Good Advice! Grab a short block & go nuts. There is a reason these cars are called Black Crack!! I hope your ready to drop some serious $$$ by the time this ride ends! :eek!:

Also for what it's worth? Something to consider? :sw:
I had Kirk at Ajax do my 1st build somewhere around 93-94?
The next 5 were done thru Martin at Nash. :wink:

Engine build

Doesnt 278killer have a complete engine for sale too.
I do! A lot cheaper than that one, and a nice build too fresh rebuild and only used one month.

This whole build will be based on what I find when the motor comes apart. I'm looking to make a reliable fun car that can throw down 11.50's and still be a fun reliable car.

I want a roller cam to eliminate the need for the oil gimmicks. And if this dosent fix the problem I will keep moving on with a very wicked new motor but I do believe there is a bigger issue then the bolt ons. The fuel pressure is perfect the BLMS are very rich and it still knocks and pings at high rpm. And everyone once ina while it will backfire and stumble from a stop sign. Sort of like its trying to take of on the rpm of the wiped cam lobe.

I paid 73 bucks for a case of 12 of brad penn oil from RP oil in whitby. at 6 bucks a bottle you can buy a lot of oil for the grand a roller setup alone is gonna cost just to avoid "oil gimmicks"

Before you go rebuilding the thing why not spend some more time and effort trying to find out what exactly is making your noise and why. Lot of smart guys in the city to take it to, or have give you a hand figuring it out. Shot gun repairing tends to be expensive.

That's the plan, Take it apart and see if it can be a simple build/Fix or if its time to go all out. I'm hoping its a easy fix. I know something is uber wrong the car ran a 16 second quarter mile at 18 pounds of boost and had more then enough fuel and good fuel pressure.... I don't think this one is a simple fix anymore I've spent a lot of time and research on this and it all leads to internals. The only other explanation is a exhaust leak and I doubt it would make that much difference and even with work out stock valve springs I've seen cars run good numbers.

So no I'm not shooting into the dark. I've traded notes with numerous Turbo Buick specialist and all three agree something isn't quite right.

I know you guys want me to shoot in the right direction but its time to build a good fun car that doesn't piss me off every time I drive it because I cant have a little boost:crazy:

I also prefer the more modern setup over the stock flat tappet cam and solid lifters.

Diagnose your issue.

If you want to waste a few thousand dollars, play the ponies.

Prove it has a wiped cam with real evidence.
