I have a 1995 Z28 SS with the LT1 engine with 85k miles. I also have a complete drivetrain (engine/ trans/ wire harness) out of a wrecked 2010 Camaro SS. My question is what makes more sense to do.

(A) build a 383 or 408 Stroker and add nitrous.
(B) drop the L99 complete drivetrain in and call it a day.

My my goals are to have a pretty fast street car to pull out on the weekends and hit the track from time to time. Will prob have drag radials on most days... it's a very clean car. I wouldn't mind being able to keep up with a CTSV or Hell Cat!!! Please help me. I'm knew to this

SS didn't come back until the 96 model year. I would go with the L99 as it doesn't have OPTI ****

The modern setup will take more work, but give you more power, mpg, output potential and reliability.

so what do u suggest? Get another style LS Motor or build the LT motor in the car?

its a z28 my mistake

**** happens. The L99 would be better for longevity and the maintenance would be less compared to staying with a LT1. Plus the power and tq stock are pretty damn good. Get rid of the displacement on demand before you install it though.

Unless you have 2014+ LT1 then modern would be the motor designed in 1997.

Ok let me find a thread on deleting the Displacement on demand thingy... I should just look for a Junkyard 6.0 or 6.2 and call it a day lol... what about the trans? Keep the existing trans or swap everything?

1955 Gen I was invented by Cadillac and they didn't want it.
1992 Gen II LT1 again was just some changes to that.
1977 Gen III LS was designed.
2006 Gen IV came out, but again it was just some changes.
2014 Gen V LT1 yet again came out and it has a lot of similarities, but way more changes than the IV

Anything from 1998 and newer will be far better in power, efficiency, potential, and reliability. Really want motors from 2000 and up as the heads were changed. 2006 has some better windage and they added DOD which you can block with a 2006 Corvette stock valley cover, but if your oil pan doesn't have the bypass you need to run a different pump our you'll see 120 psi around 5500 rpm. Melling 10295 is a good one, just clean it before using to be safe or you can use the 2006 covette pump.

You would be better off with a Gen I motor and getting rid of the Opti spark than the motor in it, but your even better with and LS or latest LT1. Best bet on price is to buy an iron block from a yard and get a new aluminum block (if you want aluminum). it's cheaper than get an aluminum from a yard.

TMC, if I were you I'd do a lot of searching and reading. Try the conversions & hybrids forum. There are a bunch of stickies. The L99 will make more power than your LT1 but you will have to make some changes to do the swap.

Yes, and the big changes will involve the operating system and electronics. If you're good with that kind of stuff, you'll make it work, but the changes aren't trivial.
