I agree you just want to change one thing at a time, and it obvious the cam is the item to change here. Leave the gear and converter alone take some cam out of it the stall will come up higher with the extra torque and the car will 60 better and also et better.

It,s got a cam in it suited more for a 13.1 472 than an 11.1 429 with a 3.59 stroke.

Just trying to help, but I guess, what I say is falling on deaf ears. I will refrain from commenting farther in fear of messing up.

Re cam it...... It will be a giant return on the investment.

Providing everything the owner of the car is saying is correct.

You said it has "mild ported iron heads". What does that mean? Mild to the owner may be too much for another, there is a big difference from clean up to hogged out. Without know much else, I gotta agree with the rest in the cam is too large for that compression. Get a new cam/lifter set along the lines with what has been said and you'll see a big difference in how it reacts.

Let me make it clear I am listening and take all opinions or advise seriously!
I did not post this to be a B.S. thread ! I posted to get opinons and advise to help my customer.
I also do feel that all have a right to there advise and opinions .

So I am going to try and clear this up so we can get this thing going in the right direction.
I do not no for sure who or how much port work has been done. I will try to get that info and let you know.

This guy is in his early 60's and has not raced in about 20 years . The car has only 8 passes on it and has the new car blues. This guy has put a lot of time money and thought into this car and he understands that it is very heavy .He does realize and understands that it take the right combination to make it fast. He does not expect it to be fast he expected to see some low 7 passes so he could get his feet wet !
So if I or he has given any miss-information I will see to it that we get that corrected ASAP!

I will post the out come of the changes and effects of the parts we change . We will be doing TNT most every weekend and I will post the out come of each tnt session. That is if you guy's are still willing to help!

Note: I would appreciate if we kept it serious and not personel. Thanks

You have your answer, its the same as the one for your own car. It ain't nothing personal if a fact. Just trying to help. It's up to you if you want to accept it.

I gave you an answer I explained why i gave you the answer and there was no b/s to it. Some others have even backed up my answer.

Do as you please.

Note: I will not participate farther.

Not mad just stating facts.

As long as the suspension is working and it's hooking and going strait.

First, Double check and verify the specs to make sure what he's starting with, a compression test wouldn't be a bad idea too.

Second, make sure it's getting fuel and is tuned properly. Timing and tune is very important.

Third! would be cam and lifters, .589 / .615 comp grind seems to work very well and will much better if he's only spinning it 6500. And it definitely needs a smaller cam with the weight, compression and items described.

x2 Car needs more fine tuning , and seat time. I don't think owner will be into changing cam, there is ways to go around it to help his setup.

Ultimatly the cam is the big issue.......

I have informed the customer that I need his cam card in hand. I also want to check the cam and see where it is set as well as check compression, valve adjustment , base ignition timming, carb jetting , type of plugs and gap settings,torque converte stall speed on trans brake with out a chip in the two step to get a better idea on the converter. I have also asked to get some flow numbers on the heads as well as how much they where ported and who did the port work.

The owner and driver has very little seat time and hasn't raced in a long time plus the car has not had any tunning with only 8 passes .
I have not drove the car myself,but plan on it next weekend !

Thanks and I will keep posting about the out come if you guy's want me too if not I will stop here.

Yes, Keep us updated

Its not enough compression for that big of cam and it to big for the operating range your looking at.

Its about 15 degrees at .050 to big and needs to be on 105 or 106 seperation if you want it to really run good. You have no cylinder pressure , cam it like a 4v clevland. Small engine big head . People that say a 4v cleveland wont run dont now how to cam them.........ii

I agree whole-heartedly, too much cam.

I did have some miss information from my customer , that is my fault as well.


I have the cam card in hand now and it is as follows:

Intake lift is 643 Exhaust lift 666
Duration@.050
Intake 258 Exhaust 264

Lobe seperation is 108 and installed on 104


Sorry again but still need help thanks !

''WHITEFIELD" have you checked the dizzy, locked out, total timing,springs?,sounds like a real nice combonations,keep tweakin. MAVMAN

YOUR WECOME,keep us posted,MAVMAN

Will do Brotha

Now verify the compression and go thru the complete fuel system.

Scale the car if you have access to scales.


Might even take it to a chassis dyno to tune it, it makes it a lot easier and faster.

So now we have the right cam specs, what gear do you guys reccommend , or converter.

Its better, what he has should work. Something else is going on. Tune? Lack of Fuel? Cam degreed wrong? No cylinder Pressure? Only getting Half Throttle?

By the Wallace Calculator this things only making around 425-435hp...... Its a Lame duck IMO

Talked with the guy that degreed the cam in and he put it in 4 degrees advanced. So I am thinking that maybe something maybe going on with carb , fuel supply, dist, or ignition timming . I am just going to have to see what everything is set on first and then go from there .

Dave what do you speculate this engine should be making ?

an old 466 I had with blended Iron CJ, similar cam, intake and carb, but more compression was making north of 600 at the flywheel. I'd think this 429 should at least do 525-550 ish. I'd think that thing should be running 6.7-6.9's in the 1/8 mile with out issue.

But again..... Same as with the cam... Whats it actually weigh.
