Who's Building What or Racing What in '08?

:laugh: :laugh:

Tim are you saying you were born at night......but not last night?

 

Oh yah -I've got a bore scope for free use if the promoters want..
Of course this shouldn't be a problem just to look in the spark plug hole while there doin the P&G to look for FLAT tops where there should be a DISH!!!
13 to 1 might be an advantage over NHRA specs.????:bla:

Don't want to be the sacraficial opposum- but we shouldn't just sit back and play DEAD !!!!!!!!!!!!!!!!!

 

those do not look like F70-14's :idea2:

 

68 Hursts came with G70x14. 69's came with F60x15. :bglasses:

 

Thats exactly what i am saying.I have done it both ways. If the roller tips are allowed,that is what i will run,unless i find some nos gm items.

 

heres some NOS GM ones --Ebay #250231084597
Looked up the comp cams made in USA rockers that donny found-
man that's a good deal- same price as mine.

Glasgo I hope you don't think this was all about you. There was a personal dig on several other camps. The only ones I left out was the guys that pick up a full second by swaping pulleys and belts whenever they want. I forgot the siiped tires!!

 

:shock: Those errr uhh are the the uuhhhh W-47 G70-14+ tires on the W-48 Hurst rims.....Seen a bunch of them this way......really....:TU:

 

I'll put some pictures up later this weekend for ya.Thanks for the info about Karl.:TU:

 

No problem, he hangs out in the Yahoo Hurst Olds page quite a bit, you can start there. Let me know what you find, he has lots of info on these cars. There are a couple of other folks over there with first hand knowledge too. :Comp:

 

I would have thought that the Yahoo Hurst Olds page was Rusty's personal home page :laugh: :laugh: :laugh:

 

Wow, Donny has been called a lot of names in the past, but never has he been referred to as a ~Saucy Fellow~.uzzled:

Isn't that just precious.:Brow: :Brow:

 

:beers2: Does that require being on the "Sauce" too long?:beers2:

 

realdealHurst,
The #1 thing illegal about your car is that the PSMCDR rules make it quite clear that excessive chrome is not allowed. :laugh:

 

......and dog dishes........

 

Tim this may not be directed at me but I felt it hit close to home. Let me explain a few things from this side of the fence.

Pontiac 1.65 rockers are scarce and only a RA IV item. The after market has quit supporting them and before that I was breaking 1-2 aftermarket ones everytime the Judge was used. I have since stocked up on NOS rockers but at $700 for my last set I am about done with that program. We have used Cranes new 1.5's and they seem durable.

To the cams, GM will not sell me a Pontiac came like they will you with a Chevy. That leaves two options, aftermarket or make your own. The Judge has a Melling which is who ground the cam for Pontiac. Excellent cam in all facets. The Boss 302 has zero support and not one single factory spec cam reproduced. I took 18 months searching for an NOS cam, no luck. Finally Marty a freind of a freind lent me his NOS cam to spin and we spun the used 30K mile factory one that was in the motor. With these cams as the base line we created an exact replica right down to factory lobe seperation and exact duration at every lift. As such we checked .050-.100-.150... No tricks there. AMC's have no factory aftermarket cams either. What else can we do but try to perfectly replicate the original? That comes 9000 times closer than any off the rack cam that was built for headers with to much duration and lift. Most AMC cams are small and no one remotely builds anything as small for them as what Rich C. or we had to run/build.

I personally started making my own cams off exact specs of the Factory pieces when I got tired of redoing motors due to junk cams that were wipping out. After three AMC's and my 455 HO went down and wiped out fresh expensive motors I was not going to put up with it again.

We break the motors in on a test stand with GM EOS break in additive and Brad Penn break in oil. We then cut open the filter and check and sometimes drop the pan for a look. Change the oil and continue with break in oil. We are going way beyond the recommended safety levels and have lost cams and motors. I have a cam company that will do what we want and we have NEVER lost one of their cams under the same proceedures used for Lunati, Comp, Crane...

I am done risking 10K motors with 2500 dollar HO heads or worse 4500-6000K RA IV heads. My RA IV's, Boss' etc have factory specs likely held tighter than the factory ever could. If anyone wants to see come look at my motors as you choose. We have always held the dyno sessions open, I have cert'd at the same time you did, and have let competitors see my builds and see cams spun.

When I write articles we give exact specs to the cams in the car. Not general specs but what actually turned up when we spun it for that motor. We have hidden nothing and note when we use one of our own built cams.

When we did Larry's LS6 we used the same cam you did. They are available, and work. Why bother changing something good. But again that is a well supported Chevy.

I hope this clears up what I have been up to although I believe it has been obvious as we have been very open and public. I want to recreate what was possible nothing more. I believe there is a pecking order to Muscle Cars and that order should not be altered by cheating. I know my RA IV's run well but they never were or are capable of what many cars are. That is fine and appropriate. For me it was never about being fastest if it were I would not spend half my time in small blocks in heavy bodies. I just want whatever I am in or I helped set up for some one else be as good as its potential allows.

One day 22 hours left and no bids at $30

I still believe if stock rockers won't hold up, the cam is too far away from stock.

 

I really wanted to make the test and tune coming up this week. The other day I took my car over to a neighboring town for a cruise. The oil pressure was fluctuating way to much, even going down to 10 psi at idle. This measurement was with the factory needle gauge, o No: so it could be the gauge. I will need to get this sorted out, before I stand on it. Any suggestions out there? Thanks Jim

 

Brian I would think your correct. The aftermarket rockers that were breaking for Pontiac's were all made by the same company (Algen as I recall and were labled by Comp/Crane...) and the heat treating was done wrong and they became brittle. I have never seen correctly made rockers have an issue with anything I have owned.

I have gotten so good at picking out the good ones I can tell the difference in the stamping marks between the older good ones and the ones that were breaking. Sad my little life is so narrowly focused that this stuff constitutes my knowledge base.

Even the used Pontiac 1.65's I have used never gave me issues.

I have a set brand new on my shelf that i am afraid to use,so unless i see it come out of a gm box,you wont see me bid.Brian,you sure seem suspicious.It makes me think of an old saying"He who smelt it,dealt it":blast: :idea2:

 

Take the oil pressure sender off and spray carb cleaner in the little hole to clean it out. A lot of times a small piece of crud will mess up their workings.
