I thought this was sarcasm at first, lol - ya, come on guys... ever heard of the "King of the Hill"??? The mightly LT5!??? Chevy produced the ZR-1 Vette from '89 to '95 that ran a Lotus designed/Mercury Marine assembled 32-valve DOHC LT5 V8 that was 5.7 litres in displacement and made 400 hp (in the later versions).

You know as old as pushrod design is it just goes to show you how well Chevy has made it work. That new LS7 427cid Z06 motor is just insane - a 50+ year old concept thats kicking but in race circles around the world.

that old peice of shit has been knocked off the hill, new king of the hill = Me, lol j/k the new gto has a 6 liter ls2 engine.

Eh the king of the hill I think is the LS7.. because hey look S comes before T on the alphabet so it's better and also its up 2 numbers past the other engine.. so it's better.

Man, that LT5 is nice and all. But man does it look like a pain to work on. There's alomost no room under the hood to where you can work on it. Though, changing out your spark plugs does look to be way easier.

Dude, dont matter if its an LT5 or LS7, they're all badass engines, but i'd personally take the ZR-1 over a new Z06 because thats my dream Corvette

Finally something I agree with the little bugger on. I would prefer a LT5 Vette myself, Its not a power thing or which is newer or faster. Its a symbol of what that car was at the time and let me tell you it was the take no prisoners bad ass road king. Sent cars home with there tail between there legs. It is like people who collect all cars. Sure there are going to be faster and more reliable cars out there but its a flash back to a time that , that car was the shit.

yea, the zr1 was a bad ass vette, but you can make it a bad ass vette angain today... ls7!


btw, those vettes are my fav, the whole front flips up so you have access to the whole engine. (not much to the 'whole front' but still.

like everbody is saying, yeah it depends on a lot of things. I just figured I'd mention that gearing and transmission/torque convertor stall have a huge affect on overall performance when selecting a cam. Swapping in an extremely large cam in an otherwise stock car will probably be slower than stock. Making changes to the entire car to match everything, gearing, stall,intake, heads, cam, exhaust, to list few are what make a fast car. I also think it's kinda funny how everybody talks about cam swapping way more than head swapping which, while more expensive can make a bigger difference than a cam swap.

Viper, it sometimes isnt all about HP and all, i'd take a Zr-1 and LEAVE IT as a ZR-1 with the LT5. Kinda like owning a 1st gen Vette.. sure it'd be cool to put a better/new I6 but the fact that it has a pretty good/old I6 is that makes the difference.

You wouldn't really NEEEEEEED to tune it up, the thing is fast even for today's standards. You take a collectable like that and modify it and you'll be totally killing the resale/collectable value of the car.

Maybe add a 150hp shot of N2o perhaps - something you could easily return to stock.

You definitely wouldn't have to modify your ZR-1 if you were one of the eight (I think) lucky people who got their hands on a "Black Widow" ZR-1. Those had LT5's tuned up by Doug Rippie - there were four different variations (or tuning packages), the full race version producing 525 hp.

Say what you will, but the ZR-1 smashed many speed records in its day, and as far as I know it still holds the record for being the only production vehicle to maintain a speed of over 175 mph for 24 consecutive hours. One thing about those motors is they were rock solid reliable. They could easily rev past 8000 RPM - the only reason they gave it a 7000 RPM redline was to keep the belt driven accessories from destroying themselves lol...

I know how fast the car is 400 HP aint something to be messed with especially since the low standard for cars is 250 HP and what is expected from high output cars is around 330, so yeah 400 is pretty good for today still.. so it isnt something thats exactly a thing of the past.
