ya lambo...get a big block...send me your 862s lol
well i went with the 454 C.I. reason been I like N/A power and big cubes means more power
Cube for cube, with the same bore and stroke per motor, Im pretty sure the LS would lay down more power. Even the L92 heads straight from the factory already flow as much as most old school big block heads. Both are great motors, but a bbc is just too heavy imo
lol on whoever said Canafail btw
Thats what i was thinking about when i read this thread.Quote:

But really the 408 in my truck breaks the 38" rear tires loose like nothing so i dont need more power lol, i especially dont need to spend more money.
I see you guys are still feeding the trolls...
another point to bring up is, i dunno about where u guys live but if i wanted to take my 07 truck and throw in a BB with a carb i would not be able to get it licensed or pass smog. So for most people on here we'd run LS motors because its new technology to go with our newer trucks. Plus an LS motors weighs less then a BB, just sayin.
A performance BBC will rev ever bit as high as an LS motor. I have a 454 BBC with stock high perf GM internals that I take to 7,200 rpm regularly. The old 427 big blocks had no problem reving to near 8,000 with a good valve train and stock high performance GM parts.Quote:

That's why a model airplane motor makes far more power per cube than a motorcycle motor. Are you getting the big picture yet?Quote:

The 500ci LS motor is a cobbled together abomination using a deck plate and a bad bore/stroke combo (small bore big stroke). Good if you're building a tractor, if you want to go fast, not so much. The LSX probably has problems with rod angularity and side loading on the pistons, where a tall deck BBC can go much bigger than 500ci and would be cranking out power easier and would be using a one piece aluminum block. Not to mention the BBC could be cheaper to build using off the shelf parts and may even be lighter than the 500ci LS motor. My aluminum 572 weighs less than a cast iron SBC.
What can a 500ci big block do? One has to look no farther than NHRA Pro Stock to find out. Six second quarter miles (current record is 6.509) with 500ci (500ci max NHRA Pro Stock rules) with no power adder. You won't find a LS motor running NHRA Pro Stock because it wouldn't qualify for the field (far too slow). Maxed out, a 500ci LS motor can't even come close!
Even twin turbo LS motors can't run the naturally aspirated NHRA Pro Stock times.
Sounds like your cousin needs a bigger radiator and/or better cooling fans. Or maybe he doesn't care because he never intends to drive it very far.Quote:

I agree, for a daily driver it's hard to beat the newer cars performance and mileage. But when you want to get serious about going fast, it's much more cost effective to move on to a big block and a carb.
I guess that makes the BBC god. lol LS motors are great little motors, but when you want to get really serious the LS takes a back seat to the big block.Quote:

This thread just turned from entertaining to a total waste of time. Some one bring it back into the amusing side please.

I will agree that there is a lot of closed-mindedness in this place. I will also agree that big block is the way. How many pros do you see using LS motors.
Don't be that thin skinned. This thread really has turned into Apples vs Lemons. Both can be made into a good drink. No point in the entire argument.Quote:

who are you talking to he said he wasent coming back :lol:Quote:

This is the first forum were i see people dont respect the BBC. Guys ino ls motors are fast but its still a small block. Ill go big block in anything if i was to build something. There nothing that a ls motor can do that a BBC cant do better. I think this forum is a brain wash to most of you guys.
NO Actually it is since when people ask any question you guys scream NELSON PERFORMANCE. lol
I disagree....i was to see a 500 horse BBC get decent gas mileage.....Quote:

ive seen 4 502ci bbc, yes i did say 4 lol, on a wind boat that each motor turned 15,000 rpms, the top speed was 35mph lol, anyways, the point i was trying to make, you can get a lot of rpms outta a bbc, o and the reason for only a top speed of 35mph, it was a bucket/crane for working powerlines in the swamp. ive seen both ls and bbc motors all run fast times, reliability and economical ill stick with my ls, but for raw power, ill go with the bbc, i just wanted to add my .02 to this and add to the entertainment :hyper2:
I never said a big block can't rev high. It's just the amount of money required to make it happen is much more compared to an LSx. I'll run some numbers on desktop dyno for comparison.
LS7 vs 454 BBC
wow! 11 pages of a thread about a question i thought was valid..
i myself was always wondering why GM didnt do a 454 LS in the 03 - 07 SS Silverados.. but maybe it was a cost savings, MPG rating, whatever...
The question was very valid. I think the answer is the additional 2k that you have to add for the lsx block. Nuff said, done imo.Quote:

Stock to stock. There would be no comparison. The ls7 would rap that big block. 454 made like 210 hp lol, but with like 450tq.Quote:

Now all out crazy NA power... sure... i guess if thats what u want... 1 mpg, idles like shit, gets hot at stop lights... no thanks, im over those days... I just wanted him to prove his speed, i dont care if i lose, thats why we race to see who can get it done... in a street race you have to get all right to go fast.... hell, my 13.3 sec tahoe would eat my 10.4 truck on the street b/c no traction.... all you guys that love BBC, go get you some of that..lol
I wish I had a 92' 454SS truck... Those were the fastest trucks GM ever made lol... or even a 70's model vette that had a big block, man those were fast!!
Hey Mic... aren't you running stock rod and main bearings in that POS motor of yours? lol... and who knows what else lol
Funny you say that I've got a 90 model sitting in the backlot that we impounded now it's a future project for my dad and I. Free truck lolQuote:

I feel dollar for dollar pound for pound and LS based engine is an all around better package. You can make the same power with less weight and less money. A 500lb lsx 454 making 750hp is rally like having 800+ with the weight saving because the car will 60ft that much faster with less tire. I ahve always noticed everyone with a big block wants to compare there 400hp 396 to a Pat Musi 800ci pro stock engine when the Sh$T hits the fan. I had a 370ci LS with a 90mm turbo that I drove 110 miles each way to the track and on 93 octane pump gas and ran 8.90's I was fastest enough that I could have won the quick eight at my local track several times. Thats pretty sad cause they were 85% BBC engines.
nope 4.6 2v n/a, its gona be a BEAST!Quote:

i think he was talking about a 454 lsx hence "why gm didnt do a 454 ls in the 03-07 ss silverados"

Now that would have been a REAL ss.
