That ac will be nice. I am doing mine in about three weeks and it is going to be hot. Now I know it won't be AZ hot but I will still be wishing I had some ac.

 

I have all the parts to do it now but I am in the debating process cause I might be either sending the spartan back to have it reground with a 4* advance or swap it with a 210x

 

Truckin, Can you compare the cams, giving advantages of one over the other?

 

The spartan is a higher reving cam that has a good lowend but it starts at around the 2800rpm mark and pulls good till the 6500rpm mark give or take, the 210x is a lowend cam that peaks at around 5500rpms give or take. By going with the 4* advance on the Spartan I get get a bit more lowend torque and keep the upper rpms as well. With that said I have seen guys in reg cabs break in to the 12's with the 210x

 

I just want to go faster....

 

I hear you brother, the easy selection from what you have said is the 210x for me. I'm still doing body work this coming week, with the A/F kit on it's way. I ran a a pair of 6.30's today using the 91 canned tune. It doesn't feel as explosive as with the SC but the times are very close. Headers are next since my exhaust got cut up. Then I'll start tuning.

 

RedTruck dont get your heart set on the 210x. You wont be able to tune it. 210 is as aggressive as you can get. 210 is a 110lsa, 210x is a 108lsa in case you didnt know the difference. Thats the ONLY difference. I'm sure you could talk weedahoe into selling you his 210 (older model with 112lsa). He's been wanting to go with the 210x.

Truckin, with the cam and headwork, you're lookin at an easy 330/360

 

Ok, guys pls excuse my ignorance. I'm use to cam discriptions being "lift: and "duration". What is lsa? I am assuming the more overlap the less it'll be tunable.

 

lobe separation. the higher the LSA, the more tuneable, the slower it gets into the power band, but the longer it is sustained. I beleive the stock cam is a 116 or 118 lsa.

The lower the LSA, the harder it is to tune, the more abrupt it gets into the power curve (on the 210 (110 lsa) it kicks in at about 2500 rpms and its at max torque by 4k). Its also a very short power curve (falls on its face at 5500).

Its something to consider for most guys, but since i (and you) cant adjust the rev limiter or shift points with DSP (which you'll need to custom tune), it was a no brainer to pick a cam that didnt need the extra rpms to get max potential

 

AF is correct the tighter or lower the LSA the more of a peak your tq curve is going to have while a lower higher/wider LSA the flatter the curve its going to have. One gives you more peak power while the other gives you more power across the rpm range. You pretty much have to find that balance.

What I am looking at is that right now when I get on it from a dead stop, because of the converter, it flashes up to 2800-3000rpms before it goes which is right where the spartan builds power, and again with mine because of the trans options, my shift schedule for WOT is up in the 6100-6300rpm range. After the springs are replaced with the head work it should be able to hold it even higher up in the rpm range though (and yes I do get up that high often) so the spartan seems almost better.

Also the spartan cam has helped put chefred in the 13.00 range in a quadcab so close to the hitting 12's. So it should be able to do it in a rcsb with the right setup.
