Need advice on new ZL1 engine
 

Need some advice on the new ZL1 engines coming out. About 6 months ago some hot rodding magazines announced GM was coming out with an anniversary 427 ZL1 engine. I called my local dealer and got put on a waiting list to be called when or if they came in. So this week I get a call that they are coming. The only hang up instead of the 16K price they are now 28K. So does any body know if this a GOOD investment which could increase in value? There is only 427 of the new ZL1's being made. Any input would be very helpful.

You could get a 1969 dated motor for that price. The new motor is not a really a ZL-1 IMHO,its a little underpowered and it would have to have the ZL-1 cam in it, (easy enough to fix). I do like the fact that Chevy is now making forged 427 pistons and a forged 427 crank again. The motor might increase a little in value after 15 years or so, but with all the ZL-1 blocks out there, it may not.

My two cents is it is a bad investment. Cool engine but bad investment.

NORMALLY (yes, there are exceptions) almost anything that comes out as a "limited edition", "last one", "only a few to be made", or "collectors edition" turns out to be a bust.

Ask all those high roller oil guys that purchase the "last american convertible" about the 76 Eldo with low miles. If I remember correctly, most dealers were getting double sticker for them in '76.

Just my 02 cents.

I think it would be a good investment if you got your hands on #1 which sold for 60K at B.J. or #427. Other than that you would be paying about 12K for a set of valve covers and a specially engraved engine plaque. IMO GM could have done so much more with that engine than they did.

Get a new ZL-1 block and build your own engine using real ZL-1 vintage parts.

Re: Need advice on new ZL1 engine
 

At introdution these motors will command the most money. Wait six months and then shop. I saw this happen with the ZL1 Ramjet(?) motor a couple years ago. First ones around here sold around 21k, a year later could buy for 14k from same dealer. You could probly do better on Ebay on a motor bought and then never installed later on.

What are you putting the motor in? Are you going to drive it alot? If it's just for the badge, bad investment, buy the 427 LS7 motor - half the price and a great motor. JMO.

Re: Need advice on new ZL1 engine
 

I was going to put it in my 55 chevy (with straight axle) but since the engine was very late to come out I opted for a 327 a just drive the car on the street all the summer. I have to say it's been a gas ser. No pun intened. And a small block to run around town works fine. So the ZL1 engine would for the time be just an investment. But I like the idea of #1 or #427 that might be the only 28K investment. Thats probably out of the question but I'll call my chevy dealer to see if thats possible.
Thanks you all that have given advice. Ed

Its not even a square port engine?

Re: Need advice on new ZL1 engine
 

“and then the ZL1 tooling will be retired forever”

I heard that 3 years ago and believed it. So, I bought 10 blocks. It took me 7 mos to get all ten of them. Maybe it’s finally true. I spoke to Scoggin-Dickey last week and was told that the bare ZL-1 blocks are currently not available with no projected date as to when or if they will be available.

I don’t understand who GM is marketing this anniversary ZL-1 engine to. If it’s the guys that grew up back in the day, good luck. Most will see it for an overpriced shadow of a real ZL-1 engine. A hydraulic roller & 460hp? On it’s worst day a real 12.5:1 ZL-1 was a 600hp engine. I build them 10-10.5:1 and they’re 535hp by the third pull on the dyno. If they think the Go-Fast guys will pay that, a 572R 720hp crate motor for 13K is about the best deal out there hp vs. $$

It’ll be interesting to see if it sells. In Nov of 06 I had a completed ZL-1 engine with the 053 block waiting for a car that was 3 months out. As a lark I decided to put it on eBay with a B.I.N. price of 25,500.00. It was gone in two days. ???

Albert (Alss) How do you build a complete Carb to pan ZL-1 engine for 13K. Please I need to know. I can’t even get close to that number. https://www.yenko.net/ubbthreads/imag...lins/dunno.gif
