Educate me--General engine knowledge
I'm not a mechanic by trade but I have done most of the work on my Tahoe myself, with help from people who know what they are doing. I have some questions that I feel like a dumb *** asking, but I don't know the answers so here goes.
1. Whats the difference beteween a short block/long block?
2. LQ4, LQ9, LQ? what's the difference?
3. Where is a good place to get a forged 408/427 built?
4. Will a Radix work on a 408/427 or is it a waste at that point?
I think my Tahoe wants to be in the 12's, possible?

I can kind of answer #2. The Lq4 is the lower compression 6.0 found in the 3/4 tons and denali. The Lq9 is the high output 6.0 that you can find in the escalade, SS, and VHO. As far as the LQ4-9 code its just and RPO code like the LM7=5.3, LR4=4.8. Most everything has a code. Your factory locking diff has a code of G80. The gears have a code, etc. etc. etc.
I hope this helps cause I think I confused myself! LOL

A radix with a 6.0 or 408 would work, but would probably not be your best bet if you want to run more than 8 lbs of boost. The radix yields awesome torque numbers, and that is what you need in a heavy SUV. Just not sure if it can feed a 6.0 or 408 enough air to put you in the 12's. Also, putting a 2.75 pulley on the radix would void the warranty and spin the **** out of the blower. Whitt1 has a tahoe and here is a quick search I did:
https://www.performancetrucks.net/fo...searchid=29189
The radix is a awesome, just need to make sure you have the right combo to make everything work. A stock dispacement 6.0 with heads, cam, and radix would be a nice combination. You could probably get close to 500 rwhp with that combo. Add a stall. 3000 rpm or so, lose some weight and shoot for the 12's. Yes, that means taking off them 24's in favor for some slicks. lol
I would try to utilize the radix since its a great unit, consider buying a 6.0, slapping the radix on there, and see where you stand. You can always add heads and cam after the fact. I think a 6.0 with a pullied radix, converter, and slicks should be good for 13's.
Hope this helps. I would PM whitt1 since he has first hand experience.
By the way, what is your ET in 1/4 now with the 5.3? Any dyno numbers?
