You could also check the prices on JEG's and Summit. (Not sure on Summit's engine delivery cost)

If you belong to a club, you may also have a discount at a dealer if you have any dealership sponsors. We save 10% from our local dealer on all items from the parts department.
I have one in my '59 (355 hp version). I went with a 2x4 carb set up, along with an MSD tach drive distibutor with remote coil to replicate the look of stock and retain the dist cover. Power is great and really makes the car fun. I have 3:70 rear so Hiway fun is possible as well. Entire set up (with carbs and new dist) was about 4k.
Good Luck

In my experience if you take the lowest price to the dealer (any GM flavor) they will match the price. Then figure out if sales tax or shipping is cheaper.
I don't know if you are completely sold on the ZZ4 choice yet...
The reason I say this is because the ZZ4 uses L98 heads, from 85 to
89 Corvettes... the L98 heads were good in their day... but the
Iron Vortec L31 heads on the 96 up Vortec 350's (truck engine) make more power than the L98's. There are some other options you could choose also if you were willing to let your local machinist do some assembly for you or do some yourself.. I don't really know where you are in the process.
I usually come at solutions from a performance angle so I will list
a few alternatives.
Buy the ZZ4 short block.. GM# 12561723
Use the LT4 hot cam ... the kit is GM# 12480002
Any of these GM heads will provide more performance than the
L98's.
1. L31 Vortec Iron (96 Truck)..... GM# 12558060
2. Small Port 185cc Vortec "Bowtie"....GM#25534421
3. Aluminum "Fast Burn" Heads...GM#12464298
Another thing you could do would be to get the GM 350HO engine
and drop the LT4 hot cam w/roller conversion in it.. the GM 350HO
crate motor comes with the L31 Vortec Heads on it... you can get the
350HO as a long block or turn key w/carb,etc..... the only small drawback is the nodular crank.. which will be absolutely fine without
nitrous under 500hp power levels.
Anyway, if you are willing to play with the combos a little.. rather
than just take what's offered...the reward will be an engine more powerful than a ZZ4 for comparible money. You could also rebuild
what you have using AFR heads and beat a standard ZZ4.
Good luck to you whatever direction you descide to go.

You could move up to the ZZ383 and get more horsepower if you want it.
I had good service from Scoggins Dickey

Phone number is on the web site. Ask For Mike Labuduvich in Service or Parts not sure.....
Tell him Mark Richman sent you from the forum ..the guy he sold the ZZ502 ..to.



http://www.youtube.com/watch?v=uGmoqtthnV4 There are parts a,b,c video
You may not need a street 820 RWHP 598ci, but if are not going for over 400hp, why open the tool box?
Let us guide you to the LIGHT...you can have the fastest street 61 in the world.

AND..... I also got a great deal on an endurashine manifold, and water pump...both installed for free, along with the rasied letter aluminum chevrolet valve covers at a very very good price.
Ask for 'Tom' in parts to negotiate ! He was excellent to me!
Kyle Dallas has a point about the L98 heads.... they are now old technology.....I understand more HP can be had with the fast burn or AFR heads, BUT there is the air going in, (INTAKE) to consider! Dennis Beck found that an Edelebrock 'Performer' intake with his 383 was as 'high' in height as he can go. I think with any better heads over L98, you can't get a bigger intake with stock hood than a performer, ..... it seems you KILL the effect of those better heads! This is my conclusion after many conversations with Scott, one of the main engine gurus at Gilbert Chevrolet.
If I am incorrect anyone please set me straight..
Personally, I wanted to do business with Gilbert Chevrolet because they were great to me giving me a lot of advice and were very helpful helping me learn all the options and to sort thru various decisons.
Check jegs/summit/gilbert/ local dealer / various sources and negotiate! Good luck!!
the ZZ/L98's.. I have most SBC head flow numbers.. I will follow up
Nassau.. your statement is a little confusing to me.. height is not the determinant issue in flow..
shape and size play a factor...and in the case of tuned manifolds length can be used to improve
torque... single vs. dual plane manifolds can effect torque also...
An example I could site on height not restricting flow would be in a short Hilborn FI set up
with individual velocity stacks... Hilborns can flow huge amounts of air..enough to support
RPM and Air hungry full race heads.

Here are some very rough Horsepower projections if the rest of the
engine was set up for a competition 355ci given these lift,flow,port size numbers.
GM L98/ZZ...............390hp to 410hp
Edelbrock Perf .........460hp to 480hp
GM Vortec L31..........470hp to 495hp
AFR Eliminator 180.....495hp to 525hp
AFR Elim/Comp/180....505hp to 535hp
The ZZ4 has L98 heads... the 350HO crate has the better flowing
Vortecs, but has the cast crank to the ZZ4's forged crank..
Here's a few part you could use putting your own engine together.
ZZ4 Block/4bolt main.. New.. Scoggin Dickey... $669.00
http://www.sdpc2000.com/search.asp?s...5123&doquery=1
Scat Forged 4130 Crank.. RPM Machine..$399.00

8 Forged H-Beam Competion Rods..Speedway Motors.. $349.00
http://www.speedwaymotors.com/xq/asp...qx/Product.htm
Keith Black Hypereutetic Pistons... Speedway Motors..$189.95
http://www.speedwaymotors.com/xq/asp...qx/Product.htm
that's $1606.00 on short block before cam/pan/etc.
AFR 180cc/port Eliminators..Race Parts Direct.. $1280.00
http://www.racepartsdirect.com/shop....25_612_613_617
AFR Heads + Budget Forged New Short block... $2880.00
certainly not a complete list.. but a little sample of what's possible.
