Got a set of those heads on the current engine...pita not having accessory bolt holes in the head. :(

Very nice.

Re: Nova stocker project.
 

It sure would be nice to see more dyno testing-with results on this forum.

Re: Nova stocker project.
 

Those are all th200 ? Who makes the aftermarket case ?

Re: Nova stocker project.
 

Glenn, the cases are GM. The two on the left have J.W. Ultra Bells on them. -Al

Re: Nova stocker project.
 

I was wondering also but I saw the bell on the floor. Wasn't sure if I've ever seen a aftermarket 200 case.

Re: Nova stocker project.
 

Went to a Coan TH350 w/low gearset last year. I've not noticed a performance difference between the two, but I sure am liking the durability of the TH350 so far. :cool:

Re: Nova stocker project.
 

Probably time for an update.

Went -.89 under twice this season (Earlville, Iowa and Kearney, Ne.) and -.88 under at Rock Falls, Wi. Camshaft had some hurt lobes when it came apart so Matt Steen and Jason Verke at Victory Engines are once again rubbing on stuff. We'll go back to the dyno after the pieces get back and are reassembled.

Re: Nova stocker project.
 

Very well done and fast !
Let us know how your freshened engine works out.

Re: Nova stocker project.
 

Good that you found those problems early.
Looking forward to those dyno sheets.

Re: Nova stocker project.
 

Yes...the lobes had begun to look herky earlier in the season but the leading/trailing edges of the nose were still okay. The lash wasn't changing but toward the end of the season it got 'flat' and unresponsive to changes so I wasn't surprised to see half a dozen like this when I took it apart.

The last pass on it was at the Div 5 Nat. Open at Kearney, Ne and it went -.88 and change under.

Stocker Life.....;)

Re: Nova stocker project.
 

What lifter are you using and how crazy is the spring pressure?

Re: Nova stocker project.
 

tell us what you found out about the spots on the cam lobes. I had the same thing happen on two different engines and got all kinds of reason's for it happening but nothing definite. Oil, spring pressure,lifters etc... etc. Sure would be nice to know for sure what caused it.

Re: Nova stocker project.
 

Alan

You should think about running the Stock Super Stock combo races @ Bandimere. There will be several G/SA cars there, so your Chevy will feel right at home. Denver's cars are usually fast so you'll have good cars to compare to.

Re: Nova stocker project.
 

Making plans to head that way next season. :) -Al

Re: Nova stocker project.
 

Thats great! Let me know when your coming. I think in this area of the country the Denver weather is better, the track is better, less wind, of course the baro is horrible but its all relative. Kearney is always a train wreck for me, I like the town but never seen to be able to get it done there, the weather always gets me.

Re: Nova stocker project.
 

Trend lifters and PAC 1409X springs.

Bill, I think there's just a certain life expectancy of this style of lobe. There's a tremendous amount of pressure concentrated on a very narrow 'peak' on both the opening and closing sides of the lobe.

This would be a good topic for the Tech section, for sure. -Al

Re: Nova stocker project.
 

Alan,
Good luck during the off-season! No rest for those in a performance based category, as there is always something to improve on or look at.

Re: Nova stocker project.
 

Sean, congrats on setting the SS/N National Record at Kearney! Doing it with a 4 cyl. turbocharged combo is impressive, to say the least. :) -Al

Re: Nova stocker project.
 

Allan,

When the 327 out of my '68 Camaro was torn down for a refresh the cam looked like yours, eat up pretty bad on both sides of the lobes. The Schubecks didn't show any kind of wear as usual. It only had 170lbs on the seat and always had Gibbs oil in it. I was going to buy a billet replacement but there was a backlog on them at that time so I put a cast back in it. The car and motor are gone not sure what it will look like at the next teardown. My engine guy was puzzled as to what actually caused this condition.


Jimmy

Re: Nova stocker project.
 

Thanks Alan!! Setting a record has been on my bucket list since getting into class racing.


Sean

Re: Nova stocker project.
 

Hi Jimmy. This cam had over 200 runs on it. It was nitrided, broken in with light springs and oil used was either Valvoline VR1 10w30 or Redline 5w20. Lifters were uncoated Trend w/o an oil hole. I'm not sure if more or less lash would make a difference or not. I'm not unhappy with the life of the cam, though. Short of going with a billet or 8620 cam core, there's not much else to be done.

Trend polished and recrowned the lifters. I just can't bring myself to put ceramic faced lifters in the thing....

Good to hear from you, hope all is well. -Al

Re: Nova stocker project.
 

Got everything back from Matt Steen's Victory Engines in Marshall, Mn. and started going back together.

Matt and Jason Verke are precision machinists that specialize in Stock and Super Stock engines, cylinder heads and intakes. They work on a one-on-one basis with each customer and are professionally confidential with your project.

Matt Steen (left) and Jason Verke (rt):

Matt's SS/K '66 Valiant 273 is a familiar sight at NHRA Division 5 and Midwest Class Racers events. To take an obscure combination like this and make it run hard gives a little insight to Matt's intellect and work ethic:

Jason is a true artist on heads. He knows what works and is constantly tweaking. No cookie cutter head work, here!

Re: Nova stocker project.
 

Wow, I bet Matt gave you quite a discount for all that glowing publicity!!
:D:D:D

Re: Nova stocker project.
 

Curious as to what kind of power that 327 makes,
and to jumble up the numbers a bit, that 273?

Re: Nova stocker project.
 

Now, Paul....you know better than that! :D -Al

Re: Nova stocker project.
 

Mark, Matt's been low 10-teens in SS/K (2,900 lbs) in decent air. -Al

Now lets see some data

Re: Nova stocker project.
 

Be a couple days before we're at that point. :) -Al

Re: Nova stocker project.
 

Whats a good flow number for a 1.940 fuelie stocker head @ .400 lift? Anyone.......

Re: Nova stocker project.
 

Got the cam broken in and valve springs changed. Made some preliminary pulls and moved the cam around. We'll get back to it after the Phoenix National event. -Al

Re: Nova stocker project.
 

Tease......

Re: Nova stocker project.
 

Alan and others,
Can't tell from the pic, but if the odd number side plug wires are similarly bunched......it would be better to be sure that 5 and 7 DO NOT run parallel and bunched together (should be separated at least a couple of inches). An odd thing called inductive coupling occurs and can encourage cross firing and you would not hear it but power would suffer a bit.;) Yeah, I know that is not the kind of stuff one hears on forums and such unless it is underlined with "some guy said" but it is a technical truth that is worthwhile to know.:rolleyes: Where did you dyno test your engine? They should have known this item from their own testing and trouble shooting.:o
Regards,
HB2:)

Re: Nova stocker project.
 

This will be a good time to test that. :) -Al

Re: Nova stocker project.
 

Finished up by testing four different fuels. Time for it to go in the car and get ready for the season.

I can't thank Bob Sherwood enough. It's his dyno that I'm fortunate to test on. His experience in not only dyno operation but data interpretation have been invaluable. Bob is truly one of the good guys.

Thank you, Bob!

Re: Nova stocker project.
 

NICE headers. Bet those were spendy.
