I would like to know more. I have been considering a Nedhead BN series topend setup that makes this power on an OEM shortblock. Little smaller but seems to make about the same power as this. Maybe the heads are holding this back.

Nice! Similar to my son's 461 on 93 octane pump gas. Also with a squishy roller. I've been telling him he needs to go with a solid and it would make 800HP.

I really thought my guy was giving me a line. He said they can take a stock z06 vette with the 427 do cam and head work and these corvettes will make over 750 horsepowet and still be street driveable. I did talk to the one guy and he has his 2006 z06 making over 640 horsepower at the rear wheels. First dyno session he said it went 617 and they changed a few things since. Also said the stock plastic intake works very very good too. This is why i was asking how or if these compare.

Re: Dyno Results LS 441CID with Straub Hyd Roller camshaft....

Out of curiosity, how much does an LSx vs Big block cost to build for similar power levels?
Say a N/A goal of 650 to 700hp?

That engine would be fun! I am more curious how much it would cost to build versus a similar big block(for those of us that cant afford a 15,000 dollar build )

Usually i think i see that big block are cheaper. The vette stuff is already more powerful then any big block out of the factory. So 750 to 800 is not much more over factory.

That's 496/505 solid roller with race gas compression territory. Any way you slice it, 750hp N/A on 441 cubes is impressive. Drop that in a 3000lbs vehicle and you're deep into the 9's. I have a little S-10 stepside that I'm thinking of building a 441 for, full interior with mini tubs. That would run circles around most anything on the street.

Nice job again, Chris.

That is true. I'm curious from a ground up naturally aspirated build. The new vettes are all supercharged

We did a GM LSX block 427 with a set of of our VEPR12X Heads that flow over 390cfm. It makes 596RWHP. This build from pan to intake fully tuned was $24K and it still needs a set of custom 2.125" headers.

Hope that works. This is the shop I deal with snd John helps or represents them too. They have been well over 600 horsepower for 6 years now. Just a few simple bolt ons. So if you have a z06 corvette heads and cam are pretty cheap. The car above had custom cam and stage 4 heads. Those heads are there own castings that flow well over 400 cfm and are about 5500 canadian dollars. They also use the stock intake. Most guys have less then 40000 in everything including buying the car. And that is canadian dollars or about 29500 us dollars. These cars run fine as a normal but rowdy car. Run 142 to 144 in the quarter mile and can cruise home with great milage. There is a video of this black z06 running 630 wheel horsepower and driving hone at over 30 miles per gallon. But to start from scratch these guys still like the big blocks for power for the buck over the ls stuff.

DANG that is a lot of power and money!
You do get what you pay for. It seems like the old big block is still the way to go for the cheapest power per dollar.
If I had 10 grand, I wonder if I could reach 800hp out of a big block chevy. It would be tough to get there though. That last 5 grand might get it there.
Right now I have about 6500 in my big block and it makes around 600 fly wheel, 520 at the wheels now. I'm sure a cam change could get me a few ponies too.
It'll go up getting rid of the th400, but in reality it doesn't matter. On the street it'll still over power the tires.
