Re: I want one!!!!
I agree that there are more powerful, more practical and definately more economincal engines out there, but just let it roll off your tongue......"four twenty seven"! Doesn't that just sound bad-a$$? Sure you can throw out "LS7" in a room full of like minded gearheads and they'd get it. But when you tell someone, anyone...enthusiast or not, that you're rollin' a 427....they instantly know it is something special even if they don't know why.
Hell I could go out (if I had more money than brains) and buy the VW W16 piece of art that powers the Buggatti Veyron (1001 hp) and it would be impressive as all hell to those who knew what they were looking at and what it represented. But it still wouldn't compare to the legendary mystique of the ZL-1 427. Just as today's "Hemi" (In Name Only) engine is technologically more advanced, efficient, and reliable then the originals......you wouldn't see a Mopar guy putting one under the hood of his '72 Hemi-Cuda resto-mod project. Maybe I'm over romanticizing all this, but I like this 427 for it's nostalgia, simplicity and historical significance, not for the dyno charts, wiz-bang gadgetry and economic sensibilities. Can't I dream my little dream without ya'll harshin' my gig?

Re: I want one!!!!
Interesting questions and ones I've wondered about...
It seems the new small block has less mass, and better head technology. I'd like to read more opinions, please. |

Re: I want one!!!!
The new LS-7 does things logically and precisely in a textbook fashion ------- this old ZL-1 takes a hammer to the textbook and does things the way it wants to (tweed blazer vs. a leather jacket)

Re: I want one!!!!
The new LS7 is also full roller, uses a dry sump oiling system, coil on cyl ignition (distributor-less), advanced composite crank and cam materials, coated everything to shed oil, etc. Complex computer management for adjustments of ignition advance, fuel/air mixture and other really fun stuff.

Re: I want one!!!!
I like my 327 small block. It gets the job done, and I don't have to stop at the gas station every other day to refuel.

Re: I want one!!!!
totally dont get me wrong i never meant to come across as arguing with someone all of your guys opinion means sumtin to me thats not what i was gettin at at all..i just meant spend the money on more realistic stuff then the aluminium block..iknow 750 hp isnt practical i never went for that i could do it and for an affordable price so i did and i agree its over kill for a street truck..of course the 427 is a wicked motor i never doubted that in fact i have one at home i guess i was just tryin to get a point and my opinion across and it didnt work apparently....rob

Re: I want one!!!!
I hate to hijack, but where can I get some cast valve covers like the 427's but for a 502?

closest i could find -- same valve covers but with chevy logo only in black, orange or cast. Your friendly local Chevy counter-man (if there is such a thing) may have a line on them though

Re: I want one!!!!
For the money,I'd take a 572,paint the block aluminum,and put the cool 427 valve covers on,and really spank them at the track, "Of course its a 427"

Re: I want one!!!!
I think its a cool engine. I hate the valve covers though. Give me a set of finned Cal Customs any day.
I have to agree with a couple of the others, its all about saying you have a 427. That was the engine to have when I was a kid. All these 454s and 572s don't do a thing for me. Yeah they are powerful engines for sure, but they just don't have the mystique of the 427. |

Re: I want one!!!!
The 396, 427, and 454 all share the same deck height of 9.8". The 427T engine has a deck height of 10.2" to allow 4-ring pistons to be used in it. This engine was used in heavy duty dump trucks, commercial trucks, school buses, etc. They were all 4 bolt mains, high nickel blocks with forged cranks and rods. The can easily be stroked to 4.5" from the stock stroke of 3.76" with the use of longer connecting rods. They're not cheap to build though, since stock intakes, distributors, pushrods do not fit on them. They are also dimensionally bigger and require a lot of modification to fit in tight spaces like camaros and chevelles, however that would probably be less of a concern to those wanting to put it in a truck.

Re: I want one!!!!
I may get pounded for this, but that first picture looks like a small block 427 to me. Am I wrong? If so, why?

Evenly-spaced exhaust ports=big block.

Re: I want one!!!!
No problem. The other obvious give-away is the valve covers. They're about twice as wide as a small block's.

Re: I want one!!!!
I share your feelings of "427 Nostalgia". I recommend you try doing what I plan to do: build your own. If you're patient great deals are easy to come by on ebay and craigslist. I purchased a 427 Tall Deck Motor for $350 just to build a monster stroker out of the block, but when I got to thinking about it I decided why waste a perfectly good forged 427 crank and set of forged BBC rods? The 427T engine all came with forged internals, so I found a 454 locally for sale on CL for $200 to drop the crank and rods (with car pistons) in. Turns out the $200 454 I purchased also came with a set of '049' heads. The guy had no idea what he was selling. With a little work on the heads and oversized valves I should easily be able to make 500hp out of my 427 running close to 10:1 on pump gas for very reasonable coin. Granted a +.060 bore will give me close to 440ci, but the old M/T aluminum valve covers that came with the tall deck that say '427' on them will never tell my secret...LOL!

Re: I want one!!!!
Its not that easy. To convert a 396 to a 427 you would need a 427 or 454 block. I don't think you could bore a 396 enough to get it to 4.25 bore. The 396 and 427 share the same 3.76 crank. The 427 and 454 share the same bore of 4.25, but the 454 has a 4" crank.

Re: I want one!!!!
I got to see this motor in person at the gm perf parts both at heartland park Topeka, the vendor had to get a rag and wipe the drool of of it. I do recall him saying limited production numbers on this baby though so by the time i would save enough money they would be all gone.... and probably antique LOL!!!!

Re: I want one!!!!
I dont know how I missed this thread, but because it was already mentioned. I think the best engine ford ever built was teh 428 cammer. I would love that engine, but I haven't seen any of them for under 15K. If I were to ever bastardize a chevy that would be the engine I would use.
