i like it. i also like small cubes. i'm open minded to it, but how much did it cost to achieve this?

I'm thinking it's probably cheaper to go conventional-----cubes plus maybe a supercharger or nitrous.

ultra rev

Back in the early 60's I helped a buddy build a high reving chevy( WE were both in the Same Auto engineering classes in college) New 327 -375 HP long block, we pulled the new engine down and installed a roller cam and the Ultra rev kit. a steel plate under the heads and springs between the plate and roller lifters. double checked all the spring pressures, polished and weight matched the valves I think he didn't reve it past 8500 but it sounded sweet. I did a 292 ford that would really rev. 7500 rpm when most fords wouldn't go past 5500.

Great video!
I love high revving small blocks, Chevy, Ford or Chrysler, Chevy is the cheapest to build.Ive built screaming 283s and 302s and destroked 350s with 4 bolt mains to 302! for less then building a 383 stroked 350! Its not that hard. piston speed in strokers like 383s at say 7000rpm is much faster then in a 283 at the same 7000 rpm ( many builders dont relize that fact) But the destroked engine has far less torque to get you moveing!!!

yeah my dad back in the 70"s they used to destroke a BBC, they took a 427, destroke 5/8 of an inch, ran 4 speeds of course.. Dad said he used to shift at around 8000 rpm, crossing the traps around 9,500 rpm.. lol thats cranking.. He went to a inline shifter from an H patteren, he didnt have the shifter setup quite right and missed a shift.. went from 2nd to 1st and gernaded the motor...lol

to achieve a build like this guy, it would cost you more now days than to build a torque moster bbc 454... destroking was the thing to do back in the day untill bigger cubes came along and was easier on the vave train to turn a engine at lower rpms and make a ton of torque... destroking is still done today so dont let them fool ya, some of these engine will still out perform the bigger cubes motors when setup right...

painted jester...... Yeah have agree there on piston speed.. yes most guy do not realize this factor when building a race engine or street motor.. altho street motors dont always turn the higher end rpms as a race engine, but still a build factor to point..

One thing i like about this video as it shows possibly how much more you need to turn a short stroke engine to produce the torque to get it to move compaired to a longer stroke engine AKA {big block}

bearing speed is another factor at high reving engines, thats why nascar engine run a 1.89 or even a 1.50 rod bearing... I know the NHRA prostock big blocks run a machined connecting rod to run a smaller bearing from a SBC 2.1 or even 2.0 on there rods to cut down on bearing speed, heat and friction

That Nova launching wheels up seems to have plenty of power! What a great video!
There are those who say that high winding smallblocks wont make good power, but I think they haven't tried building one, or at least not given them a good try.
I've always been a fan of the old 301 SBC combo and the 283. Both can be so much fun hanging out in the high rpm range, and doing it so effortlessly. My present car is running a little 327 that I wish the budget would allow a destroke, but it's a late model large journal 327 and the cost of destroking is a bit higher than it was with the old small journal 327's. It still pulls 7,000 rpm's with a 2 bolt main assembly easily, but I'd love to make it a 301 someday!

valve train durability is the biggest issue with high rpms... this guy I believe ran titanium valves to help lighten up the valve train a bit making it stronger as well... There defantly is no sound like a high winding SBC.... defantly pretty cool!!

Ok, but how much would it cost, approximately, to have an engine like the one in the nova?

The other thing is, i feel, a more conventional "low rpm" chugger would be more reliable.

i want to race frequently at different tracks and have no or little maintenance. i would rather concentrate on racing as opposed to frequently tinkering on the engine. Or course some people love constantly working on the engine.
