Well.. there are pros and cons to the swap.. i have a 3.4 and have stumbled upon an entire LT1 swap for 1500. The Lt1 swap includes everything.. engine, tranny, driveshaft, gas tank(not sure if needed, but why not?), rearend, front k-member, springs, shocks/struts, gauge cluster, torque converter, radiator, starter, powersteering pump, a/c compressor, alternator, and you will need an exhaust system manifolds/headers, catalytic converter, cat-back system and maybe more.. not sure right now.
Obviously the con to the swap would be to do the work involved, and the major increase on insurance. Pros would be newfound power, and not worrying about those damn rice patties around town. Anymore questions just pm me and I will get back to you.

the insurance company goes by the vin# not what engine you have.. they wont know what you have under the hood.. they will jsut insure you for the same price as a V6

Yeah its pretty much more cost efficient to go trade in or something. But if you have the time, money, and patience......

well i don't think that it should be extremely hard. when i first got the car my father and i rebuilt the motor but it only took us a long time because we didn't have to whole motor out we just did it in the bay. For me this is a good deal because i found a z28 for 5000 but insurance was going to be an insane rate of 6500 a year. Also just wondering if that kit included the wiring harness and ecu?

The seach feature is here for a reason.

The guy in the above link did the swap, but basically said he wouldn't do it again. Apparently the swap will Nickel and Dime you to death.


The general consensus is that it isn't worth the time and effort to do the swap. There are a lot more parts required to do the swap than first expected. Also the insurance issues would tend to worry a lot of people. Sure you get the V6 rate, but if you wreck your car and they total it, you're only going to get reimbursed for a v6 car.

Do the swap if you love working on engine stuff
If you are guy that takes his car in for an oil change to a mechanic then go trade it in for a V8

Kitt4000 said that if i drop a cam in while i am rebuilding the motor that mabey i towuld have to have the computer tweaked. can i drive it w/o the tweak until i can get around to it?

If you're going to go ahead with the swap, it is a very good idea to get whatever engine mods you had planned for the future performed while the engine is still out of the vehicle.

Putting things like the LT4 Hot Cam in while the engine is out of the car will make it 50 times easier. And yes you can get around with a new cam without getting it tuned right away, but if the cam is aggressive enough you'll want to get it tuned as soon as you can.

finally got a chance to sit down and take a good look at the prices on the cam. Cam seems reasonable but do i need the whol hot cam kit if i am putting it into a stock lt1?

I'm really not sure on that. What all does the hot cam kit come with? If it comes with valve springs, retainers, gaskets, pushrods, etc it may be worth it because you'll want to upgrade those components for the new cam.

Another thing to think about is long tube headers. Since you're putting a cam in the car, the headers will be even more helpful than on a stock internal car.

it includes Cam, 1.6 Roller Rockers, Springs, and Retainers. I was just thing about doing internal things right now since now is the best time to do it. Do i have to get headers right now.

Here is the setup that i have so far( or that i want)
-lt1
-lt4 hot cam (possible kit)

if i get these things what else would i need to put on in addition to the car.

You don't HAVE to get headers right away, but you'll really be holding your aftermarket cam back from its true potential. The stock manifolds don't work nearly as well as long tubes. But headers are like tuning, you can get along ok without them, but you'll be really glad once you get them.

Angry v6 to v8

I've started the conversion and I've ran into a few problems. The major problem that I have right now is tring to mount the lt1 motor mounts to the v6 k member. The guy at www.v6conversion.com seemed to do this but I really don't want to screw this up. Should I invest in a new K member or just try to adapt it to the v6 old k member..?
