- CNC-Motorsports Pump Gas 565 Big Block Chevy engine laying down an impressive 765+ horsepower and over 690+ foot pounds of torque on pump gas. The foundation for this engine was a Dart Big M block, Eagle 4340 Crank, Eagle H Beam Connecting Rods, SRP pistons, Total Seal Piston Rings, Cloyes timing chain, Custom roller cam and lifters, Brodix heads and Intake Manifold. Topped off with an AED Holley carburetor. If your in the market for a crate engine or all our race engine give us a call or visit our web site www.cnc-motorsports.com
Your engine put up great hp and torque numbers, very impressed.
I run 565 it run 9.06 et 1/4 at 154 mpr red line 8600 rpm get 1 you will like it
Lot of everything just for the street.
An absolutely incredible engine, but if you aren't rich just build a bored out 454 or if you got xtra cash flo do a 496 with a solid roller and spinit good. Its all good, cheers!
What? So building a 565 with a good hydraulic roller that makes 750+ hp w. shaft rockers etc. is much cheaper than a solid lifter 496? What insane planet are you on? They will cost about the same, and if you want to run solids in a 496, you might as well run solids in a 565. Not even sure why anyone would spend a lot on a 496 unless there are some kind of class rules in racing that dictates the cubes.

You completely misunderstood what Toby was saying. He was NOT making a reference to the valve train, he was talking about being more affordable to build.
He is saying there ARE options for people who are not rich. The 496 BBC Toby mentioned is like the 383 SBC and it has nothing to do with the cam being solid or hydraulic.
People build and run these strokers because they are CHEAPER by thousands of $$ to build! People DON'T have to spend big $$, that's the point.
496 BBC and 383 SBC are the CHEAPEST strokers to build because the stroker crankshafts are everywhere for almost as cheap as a stock replacement and you can use a stock block so you do not have to spend the extra $$ for a Dart Big M Block. You don't have to have super huge and expensive heads or a Dominator carb to make decent power, BIG-BORE motors require expensive cylinder heads not only to fit but also to accommodate super high valve lift to flow enough to air to feed these huge engines at high RPM. This requires special pistons to solve piston to valve clearance issues etc, etc. Setting all this up right takes specialty tools and a LOT of time and expertise to figure out which equals expensive $$ beyond what the parts cost.
This 565ci build is probably $20,000. I also understand you are getting a LOT more than just parts for $20k too so I'm not shaming this build in ANY way. It's worth every penny I'm sure of it. It's all about what I can afford and the best bang for my limit buck.
What Toby was saying is you can bore a "good" stock 454 block out .060 over and throw in a SCAT 4.25-inch crank in it and spend a few extra dollars on the right pistons and valve springs for a solid roller cam and end up with 600-650 hp with the right parts and some hard work yourself for $12,000 CHEAPER than what this Dart Block and Brodix Heads 565 will cost.
It will NOT make as much power or last as long as this 565 build but it will be super fun and probably be as close as most of us "poor-boys" will ever get to the power these $20,000 builds can make because we simply can't afford them.
The same thing is true with a 383 vs a 427 or 434 SBC build. When you can use a stock block 383, 385, or 389 ci engines to make decent power, you can saves $$$$$ over buying a Dart SHP block and super expensive heads.
Is a Dart block 434 SBC with CNC ported AFR Eliminator heads better? HELL YES, but have you priced one lately? My god, for what it costs to buy one built, I can build a 496 BBC with the same power and have money left over. Or like Toby was eluding to, build the 389 version of a 434 and get within a 150hp of it and save over HALF the $$!
Just FYI, if I do ALL the work myself except for cylinder boring, line boring, decking and balancing, I can build a 600+hp 396ci SBC from a .060 over stock block and a 3.85" crankshaft for $7500-ish and then put a 250 shot on it for $600 so with around 850 hp I'm all over this 565's ass and THAT my friend........... is RACING.
This keeps the race tracks FULL! Ask CNC-Motorsports if I'm lying? Lol.
At the end of the day, it just depends on how much you're willing to invest (or how much money you have) vs how much work you're willing to do. We all want these super builds but sadly we can't all afford them so we find OTHER ways to go fast which usually means doing the work ourselves.
Hella good numbers for a street motor! Wonder what it would have made with a solid roller?? Sorry I don’t mind the annoying to some adjusting valve train lol.
My 565ci bbc made 948hp at 7650 rpm and i shifted at 8600 rpm
Nice street engine, but you said it has roller and shaft rockers,,,,
He said hydraulic roller. And shaft rockers are just a plus in any situation.
I run a solid roller in a street engine, and it's not an issue.
Most people who have issues with solids on the street, do so for one out of two reasons. 1. An unstable valve system. 2. Poorly secured poly locks.
I never touch my lash, but check it on a regular basis.
Best trick for the street is to run a slightly hotter hydraulic roller cam, and then run solid roller lifters that are zero lashed when cold. (All alu heads and block for this).
Sweet
NICE!....HOW MUCH $$$?
Scott h what does your car weigh
How much for this motor but a solid roller cam?
Ima guess 20k
Same price probably, or really close. Only thing this engine really needs is a cam, spring and lifter change, and the stuff in there, is already at the same price. Solid roller stuff is generally not more expensive than high end hydraulic roller stuff. It's just more fun and better.
I know good for the drag strip but that would be okay for a tow vehicle
My 565 cubic inch big block Chevy made 948 horse and 840 foot-pounds of torque run 906 at 154 mph in the quarter mile my friends didn't like my motor
@@bigredracer7848 yes im sure it was made for all out racing, this is a street motor
how often do I have to rebuild this motor
If you use good hydraulic roller lifters such as high end Crane lifters, it can go thousands of miles in a street application. Top end would probably like springs and lifters @ 1500-2000 hours, but other than that, it looks like a solid build that won't need much.
Of course if you beat the crap out of it and constantly abuse it, it won't last long. But that goes for a base 6.0 LS as well.
