You have to remember this is a budgeted project. 2200 bucks for a 396 stoker kit+cost of boring the block + cost of assembling the block. I see it being more cost effective way to make the power and go the speed wanted by my friend Dave. From what I have seen the LT1 motor drops right in and bolts right up. The LS1 motor you would need a good amount of custom fabrication, and custom mounts and kmember. Just a lot of extra work. I mean give us some input on this just look at it with an open UNBIASED mind please.
PS--I myself have a 2000 z28 LS1 lol so I too wanted to say LS1, but this fell in my lap

OK, well then this is allot different then the first post that said,,,

Based on those statements 99% including me ( And I am an LT1 guy ) are going to say the LS1 motor will make the power (plus the reduced weight ). So the LS1 would be a better way to go.
For a real buget upgrade into a 3rd gen, well if you have the LT1 motor then use it!
Now, making a 396 LT1 motor is going to cost more, allot more then $2,200. Sounds like You compared a LT1 kit ( probably rotating assembly ) to a complete LS1 motor. I complete 396 LT1 stroker is probably only slightly less then a complete LS1 stroker ( I'm thinking simple boring versus resleeving?).
Even if you get an LT1 shortblock (rotating assembly AND block prep for $2,200 ( which seems real low! ), you'll need head work, stock heads aren't going to flow enough to feed 396CI, nor is the valve train good enough, Cam, springs, rockers, probably lifters, and you also need injectors and of course tuning etc. I would put a low budget 396 LT1 more in the $6,000 range.
Budget 10's with an LT1 in a 3rd gen? Hum, Sure sounds like a fun idea. What about just putting stronger pistons in it, upgrading the valve train and then hitting it with a 125-150 shot of nitris and hope the drive train holds together for 10 seconds! And you will probably need the expert hand of NJSpeeder to take a few hun. pounds out of the car too.
Keep us posted.
