I was just basing my input on the cash situation.

If you got it, then do it.

Ducky -this will might make you sick...

6.0 L

Yeah the money isnt an issue with me.

I wanted to break something when I saw that deal, until I noticed it had 83k on it. Then I was like oh well hell. Plus a couple years or so from now when I get tired of the 5.3 I&#39;m gonna probably go 408

[1BADC10]

I say mildly tuned b/c I still have TM loaded, and I haven&#39;t been able to put the log time in to maximize for performance. With the mods I have (minus LTs), the truck should be in the low 13s, maybe high 12s. I&#39;m sure it has mid 12s in it, but can only flow so much exhaust with stock manifolds. That, and the cam I had previously, didn&#39;t allow for max flow output.

I&#39;ll be able to prove how fast the truck can be once I&#39;m able to order an FLT next month. If I can get a weekend yard pass, I&#39;ll be in TX to see a pro tuner, and hot-dog it back to LA terrorizing all that wish to be stumped on.

As for your questions, I have a GM posi (10-bolt 8.5" rear) with Richmond 4.10s. Sure, as I&#39;ve planned, it is a street/strip truck. In the beginning, I&#39;ve driven it as a DD (100 mile trip to/from work), and plan to use it that way at least 2 - 3 times a week. I got great gas mileage at 19mpg w/ a faulty lockup circuit. Dying to know what it will do with new trans, and a WORKING lockup. That&#39;s better than the 15mpg my &#39;02 Yukon gets.

I am sure as well it has mid 12s to low 13s in it. I mean I was looking at your setup and it was just boggiling my mind why you only could do a 14 second pass. Then you mentioned this and was like ohhh ok. I mean your truck probably weighs right at the same as mine and I was looking to get into the mid 13s with my setup.

Were you going to go with a level 4 or the 65e?

[1BADC10]

FLT Level 4...

The 14.37 was the first time out. Unfortunately, I only had time to do a one pass time trial (14.67), first round bracket race run (14.4x), and second round run (14.37)... just with timing adjustments ALONE. Would&#39;ve done some more tuning in between, but I knew nothing about checking your dial-in before running. They posted my dial-in at 14.80 b/c the polish ran down my window making my 14.30 look like 14.80.

I&#39;ve done some tweaking since, and it pulled harder than that night. If you notice my video, the truck bogged heavily off the line, and seemed to fall off at about 5K+ rpm. Minor AFR adjustment vs RPM seemed to fix that. I haven&#39;t been back to test since trans issues started. I&#39;m confident that it&#39;s at least a 13.5 truck, but there should be more with recent cam swap. Gotta revisit my tune again.

Also, suspension, brakes, and street tires prevented me from being able to powerbrake to 3000. I could only go to 1600-ish before spinning wheels. I guess TM also played a factor in that. I&#39;ve made some adjustments since the cam install, bought some new tires, and can stall up to 2600-ish before noticing wheel spin on concrete pavement. That&#39;s improvement. Should hold up to 3K when the slicks are mounted. Just getting anxious to buy trans, but no funds available yet.

[ducky]

When you get the FLT, are you going to remove all of your TM?

On another note, I asked Allen what cam would go well when I go F/I, and he said the 220 has been responding well with the front mount. I noticed SC mentioned how the bigger the lope, the worse it is for a turbo because the exhaust gases escape. Is the LSA what determines the lope? If it does, what LSA would be good to go with without losing anything?

[1BADC10]

Ha Ha... don&#39;t know if I&#39;ll remove ALL of the TM. I know quite a few FLT owners that have 0% TM, and can break everything BUT the FLT. I guess my confidence level with stock trans blew the 0% TM idea. I&#39;m sure the FLT can handle that. We&#39;ll see.

I cannot say which lsa is best for boost, but yes, the lsa you select does affect the lope of the motor... lower lsa = more lope. If ya want close to stock, go with a 114 or 115 lsa cam. I&#39;ll post a vid of my 224 cam idle when the upload completes.

*edit*

Comp 224/224 .568/.568 114lsa cam idle w/ idle set to 600rpm

That sounds pretty sick. Do you have electric fans with your setup?

[1BADC10]

yup... need to upgrade. They don&#39;t pull enough air to keep the truck cool in the summer heat. I read somewhere that the vette fans and NBS truck fans pull at least 6000cfm. Mine only pull 2000cfm. I&#39;m fine with it on the highway, and in cool weather, but summer heat overheats motor within 2 minutes. God forbid a traffic light cycle last that long.

Pay attention to when the video first starts. You&#39;ll hear the fuel pump prime, and the fans whine. I may go back to a stock fan clutch & shroud. I&#39;ll see what the local salvage yards have in stock.

[ducky]

Edit*

Real question I have is, how much more does the 5.3 weigh than the 4.3?

[DBYRD]

can&#39;t be a whole lot, my truck sits the same height now as it did with the 4.3 and nothing else has changed. the aluminum heads kick ass&#33; idk exact weights but id guess no more than 45 pounds diff if that.
