Re: 5.3 swap

very carefully. i though about doing it but it seemed to much for me at the time. college budget.

you need

-engine
-trans/new bell housing
-ls1 k-member
-ls1 oil pan
-ls1 intake manifold
-ls1 steering rack
-ls1 radiator
-computer/wiring harness

helpful but not necesarry

-springs and shocks front
-gears/lsd
-ls1 cluster board

Re: 5.3 swap

whats the difference in the v6 and v8 k member and I got the trans along with the motor will it work?

[flamingchicken]

Re: 5.3 swap

k member has different mounts for the v6 engine than the v8.

the trans you have is a 4l60e and will work.

Re: 5.3 swap

is it worth trying to modify the 6's k-member, I have a fully equipped shop or just buy another. Ok i wasnt sure if the tail shaft on it was longer than car trans's

Re: 5.3 swap

its actually pretty cheap to get a ls1 k-member, i think the junk yards around here were wanting like $120

Re: 5.3 swap

If you can cut,measure and weld then fabing the k member should be no problem. the stock 5.3 intake is better than the ls1 intake. The only problem is you cant get it under the hood. So if you fab everything up right You could keep the stock 5.3 intake.

Id say keep your good gas milage fireturkey and when you want more power sell that 5.3 and your bird and get Z z28.

I bought a 98 Z with 70k milea for 4100. I see them all the time for under 5 g's and v6's for over $4,000. If you play your cards right you can atleast brake even.

Re: 5.3 swap

no you cant keep the 5.3 intake. go look at it, its way too tall.

and most people dont posess the proper abilities to fabricate a k member to not only hold the weight of the engine, but also hold the power thats going in.

Re: 5.3 swap

lol anything is possible. I know its taller. Like it say IF he or a friend has alot of experience, it can be done.

I would build a tubular k member with the mounting locations 2, 3, 4, or more inches lower. Then you would have to do th same for the trans. Anything is possible. If you can weld there is a way.

Re: 5.3 swap

Not looking to sell my car, spent to much time and money on the exterior to sell it for just a trans am or z. Another ?. Will the torque converter outa my v6 fit in the 4l60e? If so that'll give me a slightly higher stall speed.

Re: 5.3 swap

both trannys are 4l60e's, the bell housing bolt pattern is different.

as for using the v6 tq converter, maybe. you have both right? i believe the input shaft should be the same between both trannys. the only difference could possibly be the bolt pattern on flywheel.

Re: 5.3 swap

No the converter will not fit. The input shaft on the LS 4L60E is different. You also need to replace the tail shaft on the truck trans for one with a torque arm mount.

Re: 5.3 swap

good info. any one know where I can get a proper tailshaft

[semperverax]

Re: 5.3 swap

Ok, Will the tail shaft off my v6 swap on the the other? Also will I need to buy f-body front drive accessories? And a/c setup? I'm serious about the swap, I have 2 5.3's now and need to know ALL i'll need to put the 5.3 from a 00' avalance to a 96' bird. Every little nut and bolt. :poke: I know Im a pain but I dont wana have to learn from my own mistake's if I can learn from some one else's.

(and my built 3.8 will be up for sale when it's pulled so everyone win's)
