Post #6? With the broken sentences it sure appears he's contemplating or dreaming about dropping a 454 from a '73 El Camino into his '87 Vette. The '87 Vette would be faster with a 2004 LS1.

Alberto - Want to let that turd of a 2004 with only a 346 cu-in motor go cheap?

Peter: Thank you for your observation, however do you know what I have on the 454cu engine, I am entertaining in pulling from my 1973 El Camino..? To inform you is a 4 bolt Main w/Aluminum heads, build as an LS-6, which I probably have to do some changes to mellow the Vette.!
However, I might install it on my 1994 instead or probably go crazy and do it on my 2004 instead..? Don't know yet, what I will do, my mind is turning, want to surprise some of this youngters, thinking they have an all out piece of crab...! Maybe I'll add some afterburners on the side..!

Well, let's see. You could pull the driveline out of the 2004. Then shoehorn a 454 into the engine compartment with the transmission on the back of it. Now, you'd need a new rear-end so you'd have to do a straight axle conversion on the rear suspension and get something like a Ford 9" under the car. But then, this seems like a real waste to take a nicely balanced car which does everything well with a very nicely running computer controlled engine and turn it into a front heavy car with a carb' d engine that's only capable of performance in a straight line. then, the funny part would be that many of the people here with their LS based C5 Vette's still would not be afraid of you on the street.

If you were serious you'd be looking at putting heads, cam and headers on the LS1. Then, if that wasn't enough, you could always put a supercharger kit on it and really boost the power. The best part is, if you get the right person to do the work, the car would start, idle, cruise and just overall drive much better than it would with a carb'd 454 in it. In fact, other than having much more power, it would for the most part run just like it does now.

I haven't even started to mention the option of building a larger displacement LS1...

Alberto, I still think you are looking at this a little odd. A 454 LS6 made something like 425HP? Maybe 450tq? The LS1 in your 2004 makes 350hp and 275tq. But is also MUCH lighter, MUCH more efficient and has a better power band. If you want to do the swap just for the heck of it...well OK. But I cant see why anyone would want to swap an LS1 out of the C5 for a carbed 454. If you really want more power, I would start modding the LS1. They seem to take mods really well and can make some crazy amounts of power. Then of course if you want to go with a forced induction setup you can make stupid amounts of power. And by going this route you will not upset the balance of the vehicle, preserving its excellent handling characteristics (i have to imagine the extra weight up front would drastically throw things off!). swapping to the carbed 454 would also be more of a hassle and more $$$ than even going with a blower.

Good luck...and post pics of whatever you do.

 

Peter Thanks for your input, it is real what you are saying and practical there is no other way around it...!
Thanks

YES...I am not going to do anything with the 454 into the Vette's, will do better with the 346's and the 350's that anything else..! Because of the weight issue primarely..! There is no reasons to spend in aluminum heads on the 454, will do better on the 350's, will see when I finish with the proyect..!
Thanks
Alberto
