    Hey everyone,

    New here - I have a 1980 z28 thats 100% original with mechanical and body. About 60,000 km.

    Like any reasonable car owner, I'd like to make more power. I'm leaning towards a new tech engine swap rather than a rebuild.

    What I'm wondering is if there is any value in a numbers matching Z. Would it be a poor decision to rip the original engine out to swap a newer fuel injected 5.3 or 5.7? Would it be worth keeping the original engine on hand?

    Thanks!

    Swap it but keep the old motor if you can.
    Numbers matching is always worth more to some buyers.....but 80 Z28 isn't in big demand. ...... yet.

    I would also just swap out the original engine for a crate engine or custom built one. You can make the replacement engine look like original one. And you "beat 'on it without worrying about blowing up the original. And then rebuild the original to stock specs ehen you have the money.

    Always keep an original motor. It could really help if you ever sell the car.
    I always keep my original parts like the radiator, master cylinder/booster, power steering pump, etc. I may get them restored one day and put them back in the car. At the very least, they would go with the car when it's that time to let her go.

    I also have an all original 1980 Z28, the one in my avatar picture. I am seriously considering pulling the original motor and trans out in the spring and replacing it with another 350. As someone earlier stated "one that can be beat on" and I won't feel bad if I hurt it. Want to keep stock hood on car and planning on storing original exhaust in order to install headers and true dual exhaust. I love this car but after having many other quick drag cars this one needs to have at least 330 -350 hp to be worthy of the Z28 designation. The stock engine at 190 hp just doesn't '' spin my crank."

    here's my experience....4 years ago and about 2800 hours gone by I set out to "just replace the suspension bushings" in my second owner 1980 Camaro. Knowing when to stop is apparently not my strong suit.

    Because after you get all those horses under the hood it will become apparent how woefully inadequate the old rear springs are and then there's the shocks, the original coils are mushy....you get it.

    Believe me I feel your pain, I love driving my 81 Z but without mincing words it is a dog, I have an LS stroker ready to drop in the car but it is so nice and original I am on the fence about doing it cause once I do that then I have to do frame connectors; and then the rear will need to be done, and so on,.. Dam if I Do... Dam if I Don't... I'm getting ready to just say F*** it and just do the swap. :whine:

    But most us have learned that its just like an addiction,That we do upgrades to our car and we just can`t stop. But this is a good clean hobby, and as long as we keep within our means and have fun, Happy 2018 to you all, 130044932860518017_26257430996_o (1).jpg
