Because when you open the hood and see that big block in there, nothing else needs to be said! Why can’t a well built big block be as reliable as an LS. I have had both, and while I love the LS, there was no way anything was going in my 69 Vette other than a high hp big block.
agreed, old school big block is a must for some things and other things ls is great, personal preference that’s like saying why are we all so weird and want old unreliable c3’s when we could go to the dealership and get so much more. Just not the same man.

Desktop Dyno tells me I'm just over 625 horsepower-with my 496- Brodix RaceRite heads, Comp .671. 254/260* with a 110 centerline and 4/7 swap. 10.5 compression so it's pump gas happy. I did go with shaft rockers (1.7) and Morel Solid Roller lifters too. So far, it been reliable and a blast to drive.
I'm thinking about swapping intakes from the Weiand dual plane to one of the new Holley Sniper fabricated intakes, Just looking for info from guys that are running them. Way less cash than the ones from guys like Hogan. I can't wrap my head around $3k for an intake.

thanks for not getting mad and letting that affect your judgement. I truly appreciate the response because it was and is a legit question.
And I guess you answered it, I think I get now that cost isn't the issue, its a big block thing.
So knowing this now, my next Q would be why not big block turbo then? A turbo basically doubles the power of an engine easily, and will increase exhaust gas pressure so higher rpms put less stress on rod caps, plus they scavenge exhaust gas kinetic energy and improve fuel economy, giving you an engine that takes less throttle position to the same output, lots of benefits and uses for turobcharger application.
I know its a lot of fab work but if you throw cost out the window for the engine then why does cost of plumbing/fab matter for a turbo? Maybe you don't want to modify the frame and stuff, I guess I understand that, but I am sure it could be done without frame mods if you are creative with plumbing. Shouldn't both purposes be balanced for highest efficiency and output?
I guess what I am suggesting is, a turbo could always be under the hood since 2018, they are like $600 now for a good one. I see 10k engine but no high quality $600 turbo to double the output and make the engine more efficient?

i think people are more open to that but mostly I think people want what they saw when they were a kid or what their dad or uncle or brother etc had and back then things weren’t turboed. You can see in shows like street outlaws...(I know I know).....but a lot of those guys are going turbo on old school big blocks so it seems the stigma is disappearing. Jim doesn’t your 427 have 2 turbos?

It hasn't had the 427 in it for years....though it's sitting on a stand in the shop. It's a 555" these days. I ran it N/A for many years (871 HP) and added the turbos a few years ago.

before any other people say it. You are displaying a lack of experience in any claim of what it takes to make something go down the road with 1000 hp
your money claims just show up as a. TBTR person
example my friends son with way too much money bought a 2018 Mustang. Then sent it out to Rousch or something and had it supercharged to 750 hp for $34k with all the correct improvements
it's not just a cheep block. It's the engine management and everything behind the motor
the real problem is people like you are able to VOTE

edit: found the wiki of it

That is the truck and the owner is nice enough to share the exact list of parts for 1k rwhp- I think around $3000 was spent. Calls it 'sloppy' or something, seems to me he is also abusing certain parts rules left and right and getting away with it lol. Theres a whole how-to for cookie cutting every single 'free cheap' mod in existence it seems like. Been a loooooong time since I looked at it but you get the point. Not saying its all easy or that cheap is even a good thing. Just pointing out that yes, factory block/computer with forced air and fuel does equate 750-1k ranges with some fair semblance, I'm not here to waste your time these motors are real and possibly drying up fast, glad I caught you in time, I think a really good outcome in terms of reliability in the hands of competent mechanical... electronic... multiple field inclined individuals... oh dear

trying to hit the 700 mark, what do you think.
BBC 496 build
-4 bolt mains with ARP studs
-scat forged crank
-scat forged h beam rods with ARP upgrade
-wiseco forged +20cc dome pistons
-solid roller Straub cam
248 253 @.050
.640 lift
108 LSA
-AFR 290 full CNC heads with 113cc CC.
-RPM Airgap intake
-ProSystems little monster 1050
-11:1 compression
ive seen some builds from mark that hit over 700 But I know there’s a lot of experience and talent going into his builds.

If you don't mind I'll make some observations
-The car is a corvette, therefore it already stands out. In that case, what purpose is there to hiding the forced induction units? Typically those are mounted for easy service or visible inspection. Also at minimum like to see the air filters unless there is a 3d printed box or other custom unit and in that case, again show it off because its a vette and already got the attention its going to get due to exterior. It will never be that kind of sleeper. This act although confusing obviously took some effort and I would say the plumbing is the crowning achievement of such a vehicle if its really a twin turbo application and the plumbing is reliable and easy to service.
-Lack of pcv suggests owner doesn't care about the engine or doesn't need to high mileage them, or has been through too many replacements to realize the devastating long term health effects of not having pcv because his engines without pcv have never went that kind of mileage. To put another way, I would never run an engine without pcv because I have to depend on it, so the lack of pcv suggests a non-dependable type car, excess pressure on engine oil seals, it will leak sooner, etc...
I appreciate the efforts of cleaning up the engine bay yet its done so well the pictures doesn't show off any of the most important parts we all want to see. Its almost like they are hiding...

Lol, oh boy. Never mind that the car is knocking on the door of running 8’s and has seen 200 mph. But, what I am concerned about on Jim’s car is the appalling lack of windshield wipers!
