There's the first one that comes to my mind. He had a Magic Stick prior to that build, and when a lifter failed, we built the 383ci short-block and he stepped down to the Torquer to get better street manners and more average torque. It was a very nice build, IMO!

I don't know what the details of the TSP 383 are, but I'm running a 383 LS1 with callies compstar crank, etc (same basic setup I remember seeing in TSP's short blocks) with ported LS1 heads, mild cam, stock intake/tb and putting just under 400 at the rear wheels. I'd guess that with a better head/intake setup it wouldn't be hard to make quite a bit more power than I am. Unfortunately I didn't come across TSP's site until after my car had already been sitting in the shop for 6 weeks (crank was backordered) or I would've bought a longblock setup from them and still saved quite a bit of money over what I shelled out for mine.

500rwhp is going to be around the max you will see a 383 make so if you are going that way be prepared to spend some money on heads and an intake to reach that power level. The 402 will have a little bit easier of a time doing it, but it still will need decent parts around it to make that power. As far as getting an LS2 into an f-body we offer conversion kits with the motors to make that work. There are a couple covers, extension harnesses, and lifter trays needed to do the swap.

I'm hoping to see 500+ rwhp on the new 383 for my Miata swap.....but it's not going to be cheap. Mamo will be porting my 102 and T/B when it's time, AI 226's, one-off long tubes, and a Pat-G cam. It's my commuter, so it's going to be an interesting challenge to keep it reliable/daily-driveable AND reach my goals.
As so many have said here before...it's all about the combination (obviously). Just take your time, ask LOTS of questions, and take care to make smart parts choices. I know, sounds simple....but there are MANY who just throw things together and have less-than-stellar results because of it. I'm sure that Matt & John won't steer you wrong.

I have a 383 ci motor. See sig below for details. It makes about 550 fwhp. But it is not a street motor. But this gives you a range of what a 383 ci motor will produce. More cubes is always better. For the same price you can have a 408 ci beast.
400hp on the weak side to 550hp on the wild side out of a 383 ci motor.

I'm hoping I will be able to afford the head/intake/cam upgrade around the beginning of next year, and I will definitely be calling you guys when it's time. I was a little sad when I saw the prices on your 408's after I found out what my 383 bottom end was going to cost me.

The 2.5 LS6 wouldn't be a bad way to go. I guess it will depend how much boost you are going to try and run. The LS6 heads will give a small compression bump, which isn't exactly ideal for boost but 10.5:1 can still handle some boost. We could grind you a custom cam, but if you are looking for something off the shelf our 224/228 .581/.588 114 LSA cam tends to work well with boost on a stock cube motor.

8 lbs would be what i would expect. i dont see alot of cars with big boost with the magnacharger set up. what is a 408ci anyway ls3? and would i have to do the ls2 swap with the knock sensor drill and tap. i just want to find something ill be happy with that i can install without to much difficulty. aside from if i do the supercharger i will let race proven motorsports do that...
