New Pace catalog came today. While flipping through I found this little jem. Price not listed on the website but catalog lists it at $21,454.00. Okay, with a price like that it's not really much more than a dream... still neat to look at though.

From Pace website: (http://www.paceparts.com/product.asp?3=56150)



Ram Jet ZL1: Part number not yet available
Getting a hold of one of these may be more difficult than hitting your state lottery. GM Performance Parts is proud to bring back a legend, if only for a limited time. The Ram Jet ZL1 is the ’69 ZL1 of the new millennium, with its revised aluminum block, a solid roller cam, large oval port aluminum cylinder heads, and the Ram Jet fuel injection system...that’s right, Fuel Injection. The Ram Jet ZL1 is ‘454 cid with a street friendly 10.2:1 compression ratio that will idle all day long, unlike its predecessor of the late 60’s. If you want a Ram Jet ZL1 get in line now, GM Performance Parts will be producing a very limited 200 of these all-aluminum Rat Motors for sale on the open market and I would be willing to bet Jay Leno already has his eye on one...make that 199!

:eek:

 

Now they need to offer it as an option in the C6!!!!!!!!!!!

 

:cool: :eek:

 

Those horsepower and torque numbers are horrible. That motor is a mess for $22,000. That motor is begging for 11-12:1 compression, some really nice flowing R-Port heads and a bigger camshaft.

 

I agree with bence. For 22k, I better get a lot more than 510 hp!! The catalog says one can buy the bare alum block for a mere $5k!! Whew!! I think I'll stick with iron.

Brett :thumbs:

 

I don't see it's weight listed in the specs. Or is that not a factor with engines? Isn't lighter=better?

 

In hotrod they were talkin about this one awhile back, the big deal is that it can idle in traffic, and gets 20mpg on the road... while still being a monster :cool:

 

That's $43 per horsepower :eek: . You can build a streetable 383 with the same horsepower and more torque for about $6k. AFR has dyno sheets for this on the website: http://www.airflowresearch.com then click on "dyno tests" at the top of the page :cheers:

Weight is very important. Not sure the weight of the fully assem. ZL1 but bare block is 110# Vs. cast iron bare block 270#.

I would guesstimate the fully assembled engine weighs around 300#.

Aluminum small block (bare) weighs only 90 pounds. That would be my choice for aluminum.

 

ZD75blue:
Point taken. However if I recall Chuck Harmon is getting like 16-18MPG on the highway with his ROD 6 speed. That's with a high compression, solid flat tappet carbureted big block.

I suppose 20MPG is an accomplishment. However I didn't build my car to be an economical machine. My motor is putting out very close numbers to that motor but costs $17,000 less :) and weighs a little bit more. I can fill my gas tank up a heck of a lot of times with $17,000.

I guess I'm just disappointed with what could have been a re-release of a monster.

 

thats one bad motor but the price is :crazy: you could buy a used c5 for almost that much.

 

Dayum!!!!!! :eek: :cool:

 

I want it!!!! In 427, carb'd, ZL1 cam, dry sump lube, Brodix heads. Time to go hot-lapping! I think my dream engine is cheaper too!

 

I'll take it if they insist.

 

Your not paying for horsepower......your paying for a serial number.

That is sweet. but even if i had that kind of money, no way would i pay 21K for 500HP :rolleyes:

 

:iagree: Exactly. It'll take a LONG time for that motor to ever be worth more
than $20k. Even if you can afford to buy a ZL-1 Camaro to put it in - it's still
not original. This is the only good reason I can think of to buy one.
Oh well - there's got to be at least 200 people around with that much cash to drop on a 500HP BB - so they should sell 'em OK.

 

They`re not gonna sell one to me for that price but it sure would be nice to have something like that out front.

 

200X$21,454....
$4,290,800

Four and a quarter+ million dollars on 200 engines. Maybe I should consider buying GM stock. :crazy:
