Re: ZL1 Aluminum 427

i would use the a 572 because of the large engine compartment. http://sdparts.com/category/gm-perfo...-zz572-engines also half the price

Use this engine in a Corvette and one needs to also upgrade the whole driveline system. Otherwise, one can count on starting to break things.

a lot depends on what you put on for tires. if you put on drag radials yes you will break parts. i ran a 482 cu in 500 HP BBC in my 1974 pickup and all it did was burn up tires. it would light up the tire at 60 MPH when i would kick the turbo 400 down to pass. great fun till the gasoline prices went up.

Re: ZL1 Aluminum 427

Hi Dick, I did contact Benny Proctor on the Thursday after the 4th. They have sold out on all 5 of their engines. He gave me another contact at another GM Dealer. They to were sold out, however he game me several leads from a search for "in-stock Dealers". I called 4 places, all of whom have this motor in stock. I asked for there absolute lowest price. I have quotes between a low of $18,500.00 to $22,500.00. Looks like I need to hold out awhile longer until/if the price falls lower. I have a price in mind and I'm ready to buy, but I need to wait until some of these Dealers are ready to "dump" their investment in these engines. If that never happens, then I'll just buy one of the ZZ427's. I don't want that front end weight though, which is why I want the all aluminum engine. Thanks everyone for your replies and assistance in this matter......Herb Evans

if you already have a BBC in your corvette just buy a aluminum block and heads and use the rest of the stuff from your engine. most likely cost you under $10K if you do your own work

Re: ZL1 Aluminum 427

Clem, actually I don't have BBC. I have a stroked 350 (383) in the car now, and I have never had a 427. Which is why I want one now, being that this is probably my last chance to ever have one (retiring this year). Herb

I believe if you want one of these engines you need to step up to the plate, the price WILL NOT drop, just get higher

In that case, you will need to change the hood to a big block style hood. However, I'm not 100% sure it's necessary for a C2, but I'm fairly sure. It's definitely necessary for a C3.

$18.5k is more than $4k below dealer cost....do they charge for shipping ?

Re: ZL1 Aluminum 427

Herb, not sure if you're still looking for one of the anniversary 427 ZL-1 engines, but if you are, here's one on ebay for what seems to be a decent price. I am not endorsing ebay nor am I affiliated in any way with this seller......................just ran across it and remembered your post. Good luck with your search. These are killer engines.

Re: ZL1 Aluminum 427

Sounds like a good buy at 16k. But as suggested ya can build one with an iron block for less than half. Edelbrock Aluminum BB heads, intake, waterpump, distributor on an iron block will be about the same as small block weight. Seasoned blocks are easy find, TRW still has 435/425 horse pistons. Stock crank, rods or aftermarket all very reasonable $. All the Edelbrock components (USA quality) are less $ than most others thru racing parts jobbers.

Ya wants the open chamber heads and pistons iffen ya wants to make the most power.

Re: ZL1 Aluminum 427

Dick,
That is true if you compare the "old stuff to old stuff" but the modern oval aluminum heads are far superior to the old rectangle ports. This is more of a factor on the street. I assume he is gonna drive it.............

Re: ZL1 Aluminum 427

Gene, I am using open chamber LS-6 pistons in the '72 with the original heads that have been treated to 2.19 intakes and a gentle massage. Makes a sweet little driver, compression is actually just a little over 9:0-1 average. Block would need to be angle milled to get the pop up even. There is about .020 difference in front to back. I can live with that.
