So I am getting back from the Middle East in couple of months and have some money saved up and want to upgrade my 2000 TA. Currently the engine is stock, but I did put in a moser 12 bolt, drive shaft and spon suspension in it. I want to do something a little different with my f-body. I’m thinking about changing engines. Initially I was looking at the LSX 454, but think that may be just a little too much power. I do want this thing to be nasty, but it needs to be streetable as well. As far as price is concerned it depends on what I go with. I don’t have 50k to blow, but I’ve managed to save a few pennies. So the LSX is still on the table but some of the other more practical options I was looking at were a used LS7/3. I’ve found a few LS7sat 15k ish, but for 500 HP id just do a H C I in my LS1 and be close to 500 hp for way less money. Then I thought about an LS3 with the LS9 super charger. They are super expensive from GMPP, but if I took a used LS3 from a camaro or vette and put the edelbrock supercharger kit on it for 7k, it says id hit 599 FWHP. Again though if I’m spending all that money and time, I don’t think I want stock H and C form a LS3. So what are some options out there? Is it worth the savings to buy a used LS3 engine, change heads and cam, buy the edelbrock supercharger and make 600RWHP for under 20k? Or go With the n/a lsx 454, or find a LS7 and do a H/C/I in it. The main goal I want is over 550 HP, and something different that isn’t crazy money. Also with the new Z28s coming out, I just don’t want to be another GM with an LS9. Plus I want it to sound nasty, really looking for a good cam, not a stocker. If I did go the supercharged route with a stock LS3, would I need to upgrade pistons crank etc. if so, then were back to it being worth buying a used LS3. So many questions and combinations. Bang for the buck and 550-650 HP, what’s the best deal?

An lsx 454 is not going to make more power than 550-650 unless your going all out on it. Start with a used ls3 and add some cnc'ed l92 heads, cam, and intake setup. See how the power feels. Once you get bored add a power adder.

id go with as much cubes as you can afford and keep it NA.

Why not forge your bottom end, decent heads and cam, and spray it. that way you can have over 400whp around town. and a 150+ shot whenever you want and your motor will be built for it...550ish at the wheel sounds good to me
