Assuming the intake closes at or around 38 degrees ABDC and using an SCR of 8.5:1, I'm gettin' a DCR of 7.4:1 on the KB calculator. This will not be a particularly strong motor. You cannot just reach out in thin air and pick a cam without doing the math.

Yeah, you're right, your motor must be producing 600 horsepower or better.

I really enjoy coming on here just to ask a general question and there always has to be one miserable old Dick that answers. Congratulations on making everyone that is a part of this forum look bad. If you want to be a ****** bag then please stay off my post.

There are better ways to get the answers you seek.

If you want good honest answers for free your in the right place.

If you want to be told you have the power of god under your hood, there's a fee for that.

you really shouldnt ask questions, or for any help
if you dont want/like to hear the correct info/answers

he just showed you a chart that supports the help/answers he gave you

and you are arguing with him, telling him he doesnt know what he is talking about

techinspector1 is one of the best guys on this board for building engine setups --on paper/in type on your screen -- so you can see what will work and what wont

he will spend large amounts of time getting info and doing dyno sims for your, and everyone elses' set up

techinspector1 is the man when it comes to helping people, and i dont even fell like you deserve to be on your own post with an attitude like that!

but that is just my opinion

I appreciate honest answers but there is no reason to give them with an attitude, plenty of other people answered this without feeling like they needed to talk down to someone. His answers are not what bother me, cans are an easy change, but I find it unnecessary to talk to someone who is just asking for **** and giggles the way he did. I did not come on here claiming to have Jesus under the hood I simply asked peoples opinions on it and I did not clarify that I didn't want people to think that meant to get on here and talk **** because they have something better, this is my first build on my own and I still do not fully understand how exactly to select the perfect cam.. I never attempted to contradict his knowledge of engines, all I am saying is that from now on if you feel like you can't answer the question that I have asked without any ******** comments then please do not bother to reply to my posts. I appreciate constructive criticism but I do not take it well if it is delivered in an inappropriate fashion,

Now, all that being said, does anyone have an idea of what would be the proper cam that I should be looking for, after I open up the heads and run larger valves and with a small nitrous shot?

Obviously you don't get it.

When a new guy comes on here and tries to bash one of the most respected members, (Believe me - you are not the first)
he can expect difficulties getting interest from anyone else.

The response to your comments by TI was pretty much along the lines of what we all were thinking. (Nobody believes that your truck is quicker than a 400HP Mustang , if you outran one - they simply weren't trying. But to be fair I'll happily race your truck with my stock 04 GTO [350hp], on any track within 100 miles of Va Bch)

TI's advice was on the money - you can't pick a cam like your picking your nose , DO THE MATH! That is the best way to get a good result.

I'll be happy to assist any way I can, but you need to show some respect.

Torque wins races bud, that's why something with higher HP can lose to a vehicle with higher to a vehicle with more torque, and the mustang is a heavy *****

And I give respect when it is deserved, and talking down to someone does not earn respect

As far as the cam the one that I have is in the range that I have been told on many forums will produce a very torquey engine such is what I'm going for and that is why I chose it, it wasnt just a guess but what cam would you recommend?

It sounds to me like you are satisfied with the performance you're getting from the motor, so I have no further suggestions concerning that. I don't have enough basic information to make an intelligent suggestion anyway. Most fellows will start at the wrong end of the truck, adding pieces to the motor when they should be improving the rear suspension and installing gears and a locker together with wheels and tires that are chosen toward a goal. So, that would be the next thing I would work on.

I regret getting sideways with you, but you have just enough smart*** in you to get on my nerves. The guy in the Mustang may or may not have been on the loud pedal, but it's a moot point anyway. I can't respect street racing anyway. What I can respect is a timing slip from the dragstrip. That's where the rubber meets the road.

If, for instance, you were to make a quarter mile pass at 14.70/96, then changed some parts or did some tuning and went 14.40/98, then you have meaningful data.

There are many things I could teach you and you wouldn't have to take someone else's opinion on another forum about what cam to use, you could work it out for yourself. Either way, I wish you the best of luck.

I to regret my choice of words, I lost my temper and I apologize. As for the traction mods I have done all that, did it back when I had the 350 in it, now I just need to do another tire upgrade, thinkin about the m/t sportsmans
