Re: Big Block vs LS

I'm not above using a LS type engine but a BBC makes power so easy......without boost, that's its a pretty easy decision. 540 all the way!!

Re: Big Block vs LS

I think both LS and BBCs are cool. I'll even admit, I like all kinds of cars, Fords and Mopars too (I guess I'll be banned now lol. ). So, I'm not getting in the middle of this one - but it's interesting to read about em all.

One thing I'm seeing here though is that both 1/8 and 1/4 miles times posted and attempted to be compared - which is difficult at best, and confusing to boot.

I'd love to see these apples to apples - 1/8 or 1/4 times posted and compared, instead of trying to map one to another.

Re: Big Block vs LS

Im surprised people still bother with big blocks myself. The magic of the junkyard LS swap is that they take boost so well with doing nothing to them and they are so cheap. I see them all the time for under $500.00. Tempting to get a G body and run one....

Sinister paid for a race gas dependent solid roller'd BBC and expected to cruise it around like a daily driver. Its no wonder it didn't work out...

Re: Big Block vs LS

I really don’t get all the hate directed at the LS. It makes zero sense to me. Everything evolves. Things get better, stronger, more durable, reliable. No different with the power trains in these cars. They have evolved with the times into something much more than the gen 1 stuff could ever hope to achieve. Kind of makes me wonder if the flathead guys got on the flathead forums back in the 60s and made fun of the gen 1 guys. That stuff will never be as cool as a FLATHEAD! We make better stuff, sounds cooler and LOOKS a whole lot better than an ugly small block chevy! LOL

But seriously. If you gen 1 guys were true to the purist form you claim to follow, then it would all be ¾ race cam stuff and what factory intake looks the best. No. The platform has evolved. Makes more power than it ever would have in the 60s. The recipe has changed to make that power possible. Multi pattern cams, the big DR-17 heads, better ways of delivering fuel and air. Evolution has occurred no matter how much you hate it. That’s what the LS is. It’s the next step in making better, bigger, more dependable power. Now we can control all that analog garbage with a computer and assist the transmission to deliver that power. We can build an engine that can spit out a 1000rwhp tune on a street car and dial it back a little and cruise with 800hp all the way across the country and back if we want. We get the benefits of a better transmission that delivers a benefit that is unheard of in the three speed world – fuel economy! We’ve evolved in a way that would make the guys in the 40s, 50s and 60s proud! Hell, our PRODUCTION cars make more than anything made in the 60s and it still delivers the groceries when needed. How freakin cool is THAT?

Whats worse in all of this for some of you….the LS has hit its sunset. The new direct port LT-1 is here and its even BETTER than the LS. God only knows what that beast will prove to be capable of by the time its phased out. We live in great times! Enjoy the heck out of the ride and be happy you were able to take part in the evolution of power into what it is today.

Or sit on the side lines and kick rocks and attempt to belittle something you know nothing about. Up to you. I’m here to have a TON of FUN and see what we can come up with NEXT!

Have you put 10, 100, 1000 miles or more?
Any picture video of your car?

Re: Big Block vs LS

I love good debates where everyone can learn from each other. Like I said in my first post, as long as we are keeping these Chevelles on the road and using them, who cares what that person's preference was for the engine.

If someone is posting there life lessons, why not try to gain some knowledge from that.

My father bought a new 64 Galaxie 500 XL convertible 427 single 4 barrel car when he was younger. Guess I couldn't learn anything from him since he was a "ford" guy.

Everyone is okay with upgrading the suspensions and boxing the frames of these cars to make them more modern, and you can put in a brand new BBC, but you aren't allowed to think about LS motors?

Fast is cool. Fast and reliable is cooler. Fast, reliable and getting some fuel eco as a side benefit is still cooler.

I think it's the other way around, the LS crowd seem to think that if I drive my big block further than to a parade or a car show it will likely leave me stranded... Seriously? Oh wait, that's wrong, it's just that if it's capable of being fast it can't be reliable like a 180,000 mile junk yard motor. Who knows, maybe they are right...

Personally, I have no problem with the LS motor, other than I don't find them particularly pleasing to look at. I mean heck, if the factories solution to dolling one up is to cover it up with a big old piece of plastic... Well, it leaves a little to be desired, at least to me it does. But lord knows that can be quick... and reliable... and get good gas mileage... and evidently damn near free to own...

But me, I prefer my big block and I plan on it being quick... reliable... and get good (decent?) gas mileage... To me I've combined the best of both worlds, I have a big cube, big block with multi port EFI... it slipped right in the engine compartment of my '66, no fab no mods, nothing, slipped right in... I can select up to 4 preprogrammed 'tunes' from the comfort of the driver's seat just by turning a knob on the console... I can select 'economy' on the way to the track and when I get there just flip it on over to 'performance'... it also controls my electric fans, fuel pump, trans cooler, converter, data logs, traction control, and about 80 other things that I may or may not be smart enough to figure out... And it ought to be pretty quick, she dyno'ed at 700 hp and 680 ft lb torque... I even opted for the 4L80E 4 speed overdrive transmission to put behind her, so as I stated earlier, at 65 I'll be rolling along at less than 2K rpms.... I'm hoping for high teens in gas mileage, but we'll have to see... And though I am building her as a driver, she won't be my daily driver, a) she's way too pretty to drive in in-climate weather, and b) I have a bunch of other vehicles that need some love too, and three of them have an LS in them... But I will drive her several thousand miles a year, I'll be taking her on vacations/road trips, and beat on her like she was built to do... only time will tell...

Sounds like an awesome set up! Should be a lot of fun. Love how you have mixed in the old with the new on that thing.

Re: Big Block vs LS

Sounds a lot like my 8.1. 503 cube BBC with the Gm LS computer to control everything. I love the dependable LS and am so glad they made it in a big block version. But we need to always remember that before the LS the BBC and SBC were the daily drivers of there time and were just as dependable.

Re: Big Block vs LS

I see technology gaining strides in power and usability, but I'm certainly not trying to keep up with it. If we all switch to an LS now are we going to have to switch again in 5-10 years to electric power? Those Teslas are frickin fast!!!

Has anyone seen an old hotrod with an early 90's vette engine in it. A good idea at the time that is now obsolete...

I'm not going to lie, I considered an LS swap at one time, but I just couldn't do that to my 49 year old car. I enjoy an uncivilized, vibrating dinosaur that gets horrible mileage and needs a few pumps of the gas pedal to start when cold. These old cars are like a time machine for me and that's how I like them.

I hope I'm not offending anyone. I think everyone should do whatever they want with their cars. I'm only sharing my point of view. Peace!

Let's clarify this. Mark sought out me. I did not look him up and had never heard of him. I had posted I wanted a big block that could run on E85 and daily drive that was fast. Just like most the people on here are attempting to do. He did not set it up for E85 and it was not reliable enough for daily driving. So don't act like I asked for a race engine that could be daily driven. Mark said he could do it. He contacted me first. Also, for the record. I never asked for a penny from Mark after it happened. I ate the $8k. You all get mad and try to put on a spin on something when I am stating the facts.

I'm not sure if your trying to put this on me or not. Again, my mistake for believing for a 3rd time someone can build a daily driver big block that's fast that runs on E85. Again, no one has posted an 8 sec daily driver big block. So maybe, just maybe it's not possible unless you want to spend an absolute fortune. I am trying to tell people if they want their cake and want to eat it too they can but as far as I know, until someone else shows me differently an LS boosted or on nitrous is about the only way I have seen done.

Prove me wrong for the budget we mentioned.
