So what would it take to build a 600 FWHP Gen1 and a 600FWHP Gen3
Yes there have been some posts with links but would anyone like to do the research and find parts deals and post parts pricing for each
Lets then compare compression ratio ,Cams and street manners.
We could even drop the power lvl down or up is someone has an idea.
1 Saying you already have core engines complete with stock rotating(already in need of a rebuild)
2 no core (no blocks)

Yes a core LS can be thousands more than a core Gen1
would it work if it is only blocks that are on hand?
this is also why #2 says no cores meaning no blocks.
i am just trying to start a base so a comparison can be made.
We have to start somewhere with a build. No used peices either , has to be something new, if you arent figuring on using a stock core.

I was hardcore Gen I for the longest time, and now I am about to build my first Gen III. Cant wait.

when i was looking for a new engine setup for my car. I came up with two choices BBC or SBC. i wanted a powerful and reliable NA motor. I didnt want to worry about dropping a sleeve or lifting heads or running over my crankshaft. There is way more aftermarket parts available for the SBC than the LSx.
Both would have the same street manners fuel injection or not. the 600HP sbc would be cheaper.

not sure how much he has in everything but i can check

another member already quoted this, but as a builder and anyone else who has built SBC's already knows this.

you have to go alot further with the Gen1 and it isnt street friendly, when compared to an ls series.
That link also gives you a nice idea on a build up.

I have some explaining to do.Any and I mean this,Any small block we had either built for us or built by us never kept it's bearings.That is why I am such a hater of the sbc.Now don't go saying I am a shitty engine builder or say the guy who we paid huge money to build our engines is a shitty engine builder because I have seen with my experience around cars a ton of knocking small blocks.I beat on my ls1 like it owes me money and it hasn't skipped a beat on a stock bottem end with 175000kms spinning 6800rpm.

Check out this thread there are a few guys with SBC that run nines on pump gas and street driven.

with power adders, and again just because you run it on the street doesnt mean its streetable, or as it goes what street? Notice any of the compression ratios, or cam specs?Sure they can run on pump gas, but do you really want to, more importantly would you want to even drive it on the street. One more time, are we talking about E.T's or engines.

I don't know about SBC and those bearing complaints? Especially when compared to the "ultra quiet LSX" ??? I 've put together 1000+HP SBC that don't have bearing problems after 6 years over 100 passes of Nitrous injection stock block, cast crank, running 10.30's in a street driven 3500lb camaro! Hmmmm... Also have one going mid 8 's in the same car about 50 passes later no problems. That of course doesn't mean they don't damage bearings, just that I don't think it's a common thing. LSX motors I think are great, but SBC has nothing to envy when it comes to staying together and making some power!

Good luck with an LSx type engine at half that power. And the W2W 352ci engine is over $100,000, so it doesn't count and it doesn't make near 2,300 fwhp anyway.
LSx type engines (T, TT, SC'ed) are blowing up all over the place on a daily basis at 700 RWHP+.

What the hell is this going in anyway, I am having trouble finding it in the thread (I'm drunk and insane).
I can't tell if it is going in a SBC original Corvette or a 4th gen F-Body.
If it goes into the old school Corvette get a BBC and tear up the streets on the weekends and park it 90% of the time.
If it goes into the 4th gen stick with a stock type set-up installation is a freakin' bitch and a half. LT1-LS1 or SBC (empty bay) to BBC.

Well while you guys bench race I will be at the track racing. My sbc will make all 3 qualifying passes and hopefully go all 4 elimination rounds(If I dont get beat.) For some damn reason out of the 35 cars that show up regularly NONE of them are LS1 based engines.
Down the road in a few years there might be some LS1 stuff out racing competitively but right now the technology isnt there.

The "W2W 352 engine" is mine and it is not 100,000. It is not near half that. What it is right now is the fastest LS on the planet. Not sure why you insist on posting mis information about us.
