Project1970 · 12-17-2002, 03:42 PM

Just noticed all of these on PaceParts.com...

ZL1 - Limited edition Gm Performance Parts Fuel Injected Crate Motor 454ci / 510 HP - only 200 of these monsters will be built!
http://www.paceparts.com/product.asp...&1=333&3=56218

88958604 - GM Performance 350/400 "Limited Late Model" Factory Sealed Circle Track Crate Engine - $4900, not a bad deal, all it needs is a carb, plug wires, headers, and a starter, and it's ready to go...
http://www.paceparts.com/product.asp...&1=333&3=56213

88958603 - ZZ4 "Limited Late Model" Circle Track Motor (355hp / 405 Torque/ 10:1) Race Ready - $4200, a bit of a better deal, needs same as above
http://www.paceparts.com/product.asp...&1=333&3=56243

88958602 - 350 HP "Factory Stock" Circle Track Motor (350hp / 390 torque / 9.1:1 /Race Ready) - $2900!!! Vortec heads, same as above...
http://www.paceparts.com/product.asp...&1=333&3=56242

12498777 - GM Performance ZZ454, 454cid/440hp Performance Crate Engine - this looks interesting, my guess is price-wise it'll be a bit above a RamJet 350...
http://www.paceparts.com/product.asp...&1=333&3=56217

And now, the real kicker...
12498772 - GM Performance ZZ383, 383cid/425hp Performance Crate Engine - Fast Burn heads on a 383, as a crate! Finally!!! No price listed yet...
http://www.paceparts.com/product.asp...&1=333&3=56214

Project1970 · 12-17-2002, 03:44 PM

One other interesting note...the Vortec headed "race motor" uses a .435/.460" camshaft...so my guess is a .460-ish lift cam is just fine on stock heads...

**1971Stepside** · 12-17-2002, 03:51 PM

Sweet...I think I will hold out and get the ZZ383. It looks like it is the standard 383 with the HOT cam. I would guess in the neighborhood of $4400!! Available in Spring 03...that should be about perfect!!

jays68yak · 12-17-2002, 04:12 PM

Ill take either the first one or the last one. Wait I dont have any money. Ok im going to go day dream about the first one in my suburban. zzzzzzzzzz

Bram · 12-17-2002, 05:44 PM

ZZ383, I'm so glad I waited.

>X< · 12-17-2002, 05:54 PM

does anybody know how much that zL1 is gonna weigh? when was the last time they made that motor?

rusty ol' 69' · 12-17-2002, 08:22 PM

They use a different part # 12497317, but it's the same setup list on the pace website. I think the only difference is in the heads it looks like pace uses a fast burn, while gmpartsdirect uses the vortec heads. Here's there price anyways: $3,605.00

And the link:

SCOTI · 12-17-2002, 08:58 PM

I would think they'll be more than a couple hundred bucks extra. The HT383 has an avg price around 3700$. The ZZ383 has the FastBurn aluminum heads which are around 800$ over the price of vortecs + it's got a single plane intake & bigger roller cam which typically only adds to the price. Remember, speed costs . . . how fast do you want to go?

Ed ke6bnl · 12-18-2002, 04:33 AM

Question on the zz4 motor, it has 10. something and the zz4 with the fastburn heads is 9. something With the lower compression heads on the fastburn is it capable of using a lower octance fuel even with the 385 hp vrs. the 355 for the reg. zz4. ?????? Thanks Ed is So. Calif.

**1971Stepside** · 12-18-2002, 10:35 AM

I agree with SCOTI, the ZZ383 will be an expensive upgrade. It will be well over 4K I am sure!!

ZL1 ---------------------------------> BOING!!!!!!

SCOTI · 12-18-2002, 04:15 PM

I heard somewhere(probably on this board) that those 'new' ZL-1's w/fuel injection were going for 20K +, but then again the ZZ430's were pricy weren't they?? I still like the 383 shortblock. Hydraulic roller cam, 1pc rear main seal, 4 bolt mains. Just add the right heads & cam/intake combo. As for worrying about loose tolerances on crate motors, how much worse can they be than a new car engine?

Cheyenne Super · 12-18-2002, 09:29 PM

as far as the tolerances being loose. I heard from an insider at gm that the assembly procedure is the same for production as crate engines except for some of the 502s and special engines
like the oval track engines and zz430s

So I agree with Scoti that the tolerances are probably going to be within "production" spec.

Also best route I have found for price/hp is the short blocks with aftermarket heads/cam and intake.
ie the 385 f/b w zz430 upgrade is approx 4500
for just 300 more I can put together a package that will produce 450 hp and 470 ftlbs. not a lot of increase, but some times those light to light drag wars are won buy a little.
also my way produces a lot better low end torque.
