5.3l Swap to a LQ4 Vs LQ9 6.0L

[Sleaper]

So if i get the LQ4, well i be alot easier to hit that 400+ mark>? later down the i will get a Supercharger. thats why i would go with the LQ4 for lower ratio. and alot of people around here say just to build the 60e , is the 80e that much better even built a lil bit over the 60e? i like the ratios it has now for the hwy and in town.... and how much would i be able to get out of the 60e if i sell it?

The LQ4 is generally used for lower compression applications so that you can use a power adder such as a supercharger or turbo. It would be difficult to have a low comp motor make 400 rwhp without any power adder. The problem becomes that you start working against your mods, meaning a cam that is good for a high comp, N/A motor does not do well with a boost motor. The other option would be to build a LQ9 that has decent off boost power and then add a small amount of boost to it (5-8 psi). This might get you what you want. Keep in mind that the higher CR you have the less boost you can safely run. Otherwise, you can build a 400+ hp LQ9 and then when you get the charger, you could change to dished pistons to lower your CR. Depends on what you want to do.

As far as the 60e or 80e, it's not even close. The 60e, no matter how "built" it is will give up once you start getting in the 500+hp range. Not to mention, the cost for a "built" unit will be anywhere from $2500-$3500. A stock 80e can be had for much cheaper and all you need to do is add a shift kit and it will probably be stronger than most built 60e's. Granted, there are other modifications that need to be made for the swap (driveshaft, crossmember, flexplate...) but it should still be less than the built 60. Not saying the 80e is indestructable, but they are a much better option than the 60e. You would probably only get a few hundred dollars for the 60e as it is now since it's got 115k on it. But that's a lot better than nothin if it gives up on you!

i just bought an LS1 cam for Very Cheap! and i dont want to get new heads too much, and just want to be rolling around the 400+ mark. all motor which i know i can reach.. !!!

I've got a Ling. LS1 cam in mine w/ head work, injectors, LT's, 80mm & tune... I'm putting down approx. 375-380 hp...(N/A)

A stock 80e is better than a fully built 60e....Been there done that!!!

well ill be putting the LS1 cam i just bought for 25 bucks! lol.. and i my buddy has a Gto 04 with an LS1 and put 375+ at the wheels and his tranny is spining and going out bad already and he says he has the same tranny just no OD and some other thing. and tells me he knows a shop around here that will build his and my tranny for about 1200-1500 and will handle 700-800hp and he says no matter how you drive it, burnouts and racing it! kind of feel like i should maybe wait an see my buddy take the dive and wait and see...

[DBRODS]

the tranny will live in his Goat, but NOT your truck.....Weight plus HP is what kills them....4l60s live in fbodys to 600-800 all the time....but NOT trucks...

Go ahead and order a Nelson tune while you decide on the rest of your mods. It sounds like your buddy with the sierra would be an easy kill if he's doing mods like TB spacers!! A tune would really your truck up!
