An LS3 does not use a 383 rotating assembly. The crank is the same but with a different reluctor but the pistons are quite a bit bigger. Stock size is 4.065" I think.
With a rotating assembly from TSP you get a 4.070" or 4.080" piston making it a 416ci motor. With a stock piston you get 414ci.

Ok. I might get a LS1 from the junkyard just to be able to work the build and still be able to drive the car. It's a thought.

What about running an LS2 block with LS3/L92 heads setup? You should be able to hit your numbers and stay under budget no problem and this way you get to use the LS3 heads.

Was never put on the dyno, but good for 12sec@118mph with a crappy 0-60, street tires full weight,, 3:42 gear and couldnt shift the trans at high rpm. Around 460rwhp I'd say.

Great idea and cheap with the LS3 intake/heads/fuel rails/injector. Thats what I had and it was a killer combo. I had a 230-236 cam with 11.1:1 CR ported LS3 heads. Stock LS2 block.
