What cam

That is not all that great to hear at this point, Im not even supported under HPT either

[sprucegagt]

HPT or Powrtuner are the only options for OBDII.

[Badassoldspower]

any other like not so user friendly software that is readily avaliable?

[SappySE107]

Im pretty sure they supported the 97 cutlass so it is just a matter of finding a used DHP tuner.

[sprucegagt]

So what is the most affordable solution to tuning?

The cheapest would be a used Powrtuner that would run you about $300. But I don't know if your Cutlass would be covered and DHP has stopped supporting the Powrtuner program.

How much did you pistons stick up over the top of the block?

I measured .019 popup on the 3500.

From PG-1..

[95Grand-Am]

i deffenetly would, i don't have any marks on the heads but i only put 800 miles on it.

.040" is the standard, the rods stretch at higher RPM's so you need a decent buffer area there.

Yep.. but my dents are .034" deep which means they would have dented anyways, just less...

Did you have marks on the head from the piston pop up or just the valves? I running a stock cam so I don't have the lift that you do. Do you think I going to be in trouble or is there a good posibility that I can get away with it? i'm pretty sure that my piston only stuck up .012" with a .040 gasket it should give me .028". I race it, and plan on running @ 4500 rpm in the corners and @ 5500rpm at the end of the straights. I don't want it to blow so if you really think I should tear it back down let me know.

.019? Damn, and my block is all apart or I would measure again.

The iron head gaskets arn't good on the 3400? I would like more info on this because I did it to my engine but haven't had the chance to run it much yet. I thought the piston only stuck up 12 thousandths. which would put the piston a tight but doable 33 thousands from the head. Using the Roll graphite head gaskets which I believe are 45 thousandths. Correct me if I 'm wrong. Supper dave ran them on his 3500 is the piston height different than the 3400?

Yes, i ran them and have the dents in my pistons to prove it.. I made the mistake of not measuring the popup and just going by what was posted in a 3500 thread. I posted the aftermath a month ago or so... I measured .019 popup on the 3500.

the ROL ones are actually .040 compressed which like they said would give you .020 clearance, you'll be bending valves in no time.. lol


all larger cams need tuning, talk to your local dyno shop and see if they have the right software to tune the car.

[SappySE107]

.010 for 3500 and .020 for 3400 roughly. Its close on a 3500 but too thin for 3400. It should run, but once you get to higher RPM, its going to be taking a high risk for piston to head interference.
