BBC vs. LS

[BADDASSC6]

REPLAY: RoadKill Live! Day 2 - Crusher Camaro Engine Swap at PRI - YouTube

This video pisses me off. This is a comparison between a $9K-12K BBC and LS7 that is easily $25K. Entering argument for an LS7 is 15K and quickly escalates when forged internals and high end valve train components are added. The dual Holley TB set up is easily $4K alone. The baby base kit is $2800.

I didnt watch 9hrs of video but my uncle just had a longblock 440ci LS7 for about $13k from Texas Speed. This is a forged motor with ported heads, a big cam, high compression and top notch valvetrain. I know a stock crate LS7 from GM is like $15K.

I have under $5000 into the longblock of the 454 in the Chevelle. For around $13,000 I could have a 540-598ci BBC crate engine making anywhere between 700-900hp.

Oh I understand. Just saying, $25k for an LS7 setup would be pretty steep. Actually, I can put together a 1000hp LS motor for $13k. My uncle just wanted to use that shop. He still could've saved a lot of money. At least he got a warranty I guess.

[BADDASSC6]

My LS3 was $15k and doesn't make BBC power. That Holley setup with one smaller TB and no intake starts at $2800. It just looks like an unfair comparison when transmissions are changed and going from a 3.55 to a 4.56 gear.

[BADDASSC6]

Nate if my motor ever blows I will contact you those are great deals.

[enkeivette]

A BBC LS7 or a new aluminum FI LS7?

I dont think a low vaccum carb'd setup would have worked for you Carlos. You'd be stalling out all of the time. Plus I think the extra 200 lbs would have noticeably changed the handling of your C6

[BADDASSC6]

I was never considering anything for my application other than a light weight LS. I was just critiquing the comparison they made.

I was just referencing BBC crate engines, not something I could build on my own.

I was gonna say, that's what the BBC 572 is straight from the catalog. Power depends on compression selection, which dictates gas AIR.

[94cobra69ss396]

Correct. But I can build one for a lot less than it cost to buy a crate engine.

You let me know. I work closely and am friends with a shop owner and a machinist. We put my motor together for a very budget friendly cost. 600rwhp through an auto and conservative tune with a smaller pulley waiting to go on.

And guess whose oil looks like a chocolate milkshake? That's right this guy. Just found out yesterday at the shop. They are pulling the heads and the oil pan to assess the damage. Looks like its a small leak the car runs strong and has no knocks. May pull the engine to freshen up the bearings is there is any material in the pan.

Is this on the Vette? I thought it was down having things done to it.

How many miles you got on that lump esse?

[C5Natie]

Doesn't take much water to kill a bearing. If you can freshen it up do it man. Better then doing the work twice later.

[BADDASSC6]

Yes it's on the vette. It is getting worked on. They are waiting on the new seats to arrive so I had them change all the fluids in preparation. They noticed the oil was milky. I gave them the ok to pull the heads. It's frustrating. The OMP seats I had won't fit with the side impact bars so I had to get new sparcos. Now this shit. They are pulling the pan and i will have them replace the bearings too. There is too much $ risk not to do it.

[94cobra69ss396]

That sucks but at least bearings are cheap. Well paying someone to do them isn't but the bearings are.

The Hello Kitty Miata somehow lost a bunch of its oil since the last change and my wife said it was making a funny noise coming home. That funny noise is almost certainly a destroyed main bearing at least, which makes me a sad panda.

[BADDASSC6]

Well see what the charge will be. I have literally spent thousands with these guys. Lol. I was watching them install a new dyno and all that was in my head was I paid for that. Oh well it's an expensive hobby.
