I'm stuck. My car has run a 13.1@103 with nothing more than full exhaust, cai, and full suspension on drag radials. I'm stuck between a 383 LTx or a 383 LSx. I have 3 two bolt main blocks sitting in my garage. For the money, it makes more sense to to the LSx swap cause u can make more power for less money. But I like the LTx and really don't want to swap the harness. Any opinions? I'm sure being the LTx forum most will say stay, but I'm just looking for some reasoning.

all about the money, and goals. IMO go LSx

Here is my opinion, spend the money on someone else already built LT1 and boost the **** out of it. I think due to the mass jumping to the LSx scene has created a market where you can get a fully built LT1 for less than what the parts and machine work would run you.

Wish I had some dough kicking around, I'd already be going poop your pants fast, and for under $6k. I've been seeing some boost ready motors on here and CZ28 for $3k and less. Also have been seeing some complete Procharger setups for $1000-1500 on both boards also.

Well that is my opinion.

5.3 block for $400 and a cam and some spray or boost for cheap. Even throw on a carb if you don't wanna mess with the harness. I love ltx but hell their cam only cars run what fully built ltx cars run.

Mcalus, the car is DD and will be for now. With a wife and kids the idea is to spend as little as I can and still have fun. If I start pulling stuff out, the car is no longer fun to drive everyday. My runs were done with my 10" sub in back, and the music cranked. I enjoy driving the car. The plan is to hit 10's on motor and then spray my way to a 9, but I'll probably only get to do it once since I'm not caging the car. And I'm keeping the 10 bolt. Lol

Just a cpl of things first of all if u hit 10s on motor and thats a big if, with a lt block u wont be able to go back out to try for 9 unless ur local track is pretty relaxed abt regulations dont quote me on this but i beleive 11.49 requires 6point cage so.......... no more kids in the back seat and wldnt say that building a ls block is less money for more hp. I own both and because ls's are all the rage the stuff to put on them and in them cost more simple supply and demand thing. So do some checking but beleive ul find u can find cheaper parts for lts compared to ls's but its all in what u want i built my lt and kept my ls (bottom end) stock. I wld compare #s and go from there just my opinion GLWYB.........fyi i believe theres a 383 block for 500 on the classifieds right now its been splayed honed , and i forget what else ,im guessing even with shipping u wont be able to do that to any of the those blocks for that price. Again just my opinion.

Good luck with 9s with no cage and on stock rear. Id keep the lt1. Just throw nice set of heads and a cam on ur stock shortblock.

duh

I did it funny that everyone keeps breaking the 10 bolt. Years ago, we had a 92 that ran a 10 bolt with a tru-trac and 3.73's that went 9.90's on spray. Broke the 700r4 before the rear. Switched to a th350 ad went just as fast. And I almost forgot.....there want a cage in that car either. But then again it was a street racer ;-)

If you want to go fast go BBC. If you want to succumb to peer pressure and be like everyone else go LSX. If you really don't give a rats *** what anyone else thinks keep the LT1 and have fun with it.

duh

iTrader: (16)

I really don't care what everyone thinks, I'm looking t overall cost. From what I've seen, I can make more power with the LSx than the LTx given the same cash outlay. The trans will need to be done either way so I'm not including that. The only additional cost in doing the lsx swap is the k-member, headers and y pipe, and the harness. Since I can sell my current driveline and all the extra LTx parts I have, I figure the actual cost to swap will be a wash. So it comes down to bang for the buck. Everything I've seen screams lsx. Am I wrong in where I'm looking?

I have two LT1's for sale a 388 and a 396. I also have a 6.0 block. Since some kids totaled my street car I have very little reason to still run an LT1. If you can get a steal on the swap then do it, but it will be expensive no matter how you do it.

duh

I have access to a salvage yard that I get awesome pricing on. I'm gonna have to call and see what a 5.3 and 2wd 4l60e are going for. I think it'll just depend on what I can sell what I've got for and go from there. The motor is going to get reworked either way. I don't like the stock 5.3 with a cam idea. Lol

cprmn14

+2. Your going to easily drop 2 grand and 3 months of time in a stock 5.3 swap.
y
Fbody front acc., harness, trans, motor,intake, oil pan. Plus your going to have to take t,e heads off anyway to make sure its not a bad motor.

Put heads, cam, 24x conversion and call it a day

It sounds to me a though you've made up your mind to go LSx and if that's what you want to do that's fine but I love my LT1 so I'm going to turbo it and keep it.

duh

iTrader: (16)

I haven't made up my mind yet. Either way the engine will be built and done before the current engine comes out. I'm not into having the car sitting on stands for months. I plan on getting everything lined up so that it's a one day out, one day in ordeal. This goes for an LSx swap or a LTx stroker. The plan is to be built and ready to go long before I remove any parts.

When people look at cost per HP few consider the costs of doing the swap...............

iTrader: (1)

More often than not, that has proven to be false.
Like 96caprice said, people overlook all the odds and ends and workarounds required. Unless you can do all the work, including fabrication/welding etc. yourself, you'll spend more going the LS route.

same thing i said abt 20 replys ago i looked the numbers over myself building a lt1 383 and dropping a ls 383 in im telling u when u add up odds and ends everything ls cost more money theres no way around it im sure u can get stock blocks,harness, and trannys cheap but when u dig into fasteners, rotating assy, heads, cam, ewp,and this is a very short list there is so much more involved,I PROMISE U THIS ANYTHING LS COSTS MORE.........
