Default 383 408 402

what will be the best way for me to go? My engine is gone and needs to be rebuild or replaced. If I go with a 383 I want to use the same block. The thing that I want to know is if use the same block how much am I saving and is it worth it. I was shoping for prices and all three assembled engines are about the same. If I have get a new assembled engine what should I get 408 or 402. I also need a shop to install it I live in houston, what shops do you recommend.

Pick up the "Bible", GM Hightech. This month has a ton of crate engines as well as bottom ends for under $6000.00. Many under $4500.00. Get the Hot Rod Magazine with the yellow 69 Chevelle on it. It also has a bunch of GM crate engines with prices and 1/4 mile times of each engine. Hope this helps. You're in the neighborhood of some great shops and dealers for what you're looking for, good luck.

Ive been looking around here on this same subject and honestly rebuilding your current LS1 seems to be more economical. Reuse your stock crank and get 3.905 bore pistons and have yourself a nice little 370. If you reuse your stock block it will probably need to be honed for cleanup purposes anyway. Anything larger than a 3.905 bore will probably need to be resleeved. Or go the other way with stock size pistons and a 4 inch stroke and have a 382.
All depends on what you want out of your motor, but there are much cheaper ways than all out buying a new motor.
