Street Legal TV's Jonathon Buckley puts Dart's Short Block and Top End Kits to the test, pushing the limits through a series of dyno tests. www.summitracin...|Asc
Steve is the" almost silent" brains of West Tech a great man , a great teacher as he is almost my age , and I have been helping the kids around me for over 40 years. Dang we are getting old Steve!
I built a big block 454 with the same Hyd. cam set up, but I used 1.8 rockers to facilitate a little more duration on the intake. That motor at 11.1 made a little over 700hp and 646 ft lbs. Torque. Dart makes great blocks. Brodix makes great heads. And you have to learn to port(by hand). No nitrous ...yet. My 496 made 82 more hp. Torque was up only 18 points. I can't wait to build a 632!
Put that 700 HP engine in a 1st generation Camaro, forget that old rice boxxxxxxxxxx

There are numerous RUclips posters who say all heads, even Darts, need to be fixed by a competent machine shop. They say the valve seats, valve guides, and bent stems are common. QUESTION is, do you re-machine the heads you use? Do you check the seats with Dyekem for proper seating? Check the valve guide for being too tight fit? Or do you always just bolt on the heads as you get them from the manufacturer? Thanks
Who is the young bloke working the dyno? As for the power? I have used similar spec stuff but with 12-1 on Avgas and solid roller with similar specs and made 500 at the wheels.
Why lifters, ignition wires, cast iron, fixed cams etc... Seems to me like these old timers don't like change. Welcome to the 25th centenary, here is my short block.. hasn't change a bit in ions.
LOL, doubting a "pushrod" engine? That iron block is cheap , reliable & can handle abuse "heat" , nitrous, turbo's, all day long, no sweat. And variable cam timing? That's not for high output engines, lol... It's to maximize "efficiency" , especially with mild or small engines. Sounds impressive on paper, but more world records are made with USA, pushrod V-8 powerplants , period ! .
Why change what works? The LS is a newer generation engine but when modified makes no more power and is a BIT lighter. Go the other way and look at Fords hitech OHC engines. Cost more and make less power. And are huge top heavy things as well.

Abit of an old video here...
But would this motor go alright with some boost?

A lot of things that are being done on the side are left out of these infomercials..
Damn I wish it was a basic supercharger kit on this test like a P1SC on like 7 or 8 psi
427 is hard to get the static compression down. -27cc dished pistons still leave about 10.5:1 with 64cc heads.
Jeffrey Binnig
That's a great point, I just assumed flat top pistons
Dart has 72cc versions too.
It's not legit without Brule
I would not run nitrous through hypereutectic pistons unless you want to scrap them out of the bottom of the pan.
they didnt either they upgraded them to forged
I did not see ware they said they upgraded the pistons.
yup they said it when they talked about the rods being upgraded
BRÛLÉ knows some stuff!
@MrCoolwaterman lots of drag racers and older guys are afraid of fuel injection. Some classes in racing require carbs.
Carbs make more power it's simple
Can I put a dart. 400 in my truck as a daily driver? With more torque than horsepower.
knobber420 go big block
I'm going to stuff one of these into a 98 frord ranger with a Muncie 4 speed with very quiet exhaust

Sweet engine to be sure. Can't believe it's going into a 240. Sheesh. Why not a '71 Camaro?
The castings look rough. Put a solid roller in it lol
and the price
Around 8 grand
Holy shit look at young Brule
Puny Cam for the top end
Why Caburator?
cheap and work great if you know how to tune them.
Why not
The only thing wrong with a carb. Is people are 2 dumb to adjust them anymore.fuel injection is for yuppies
More power, simpler, cheap.
@@stillwaiting4315 How 'bout TBI for us in between dumb and Yuppie :)
lol at putting that motor in that car.
Oh God, you put that sweet engine in that shitbox car??
He says DOT for DART.
He also says Pot for Part..
How long has Steve been bald?
he isnt bald thats the new clear hair
Born bald
What did he say his name was? Buck who? Buck Naked was it?!?
HAHAH nice

the higher end LS engines are making 2k+ hp and much more common and affordable parts.
with twin turbo's-

Only gave it the thumbs down not for the brand “Dart”, but the design of the motor “Chevy”
Can't blame you for jealousy... Ford pimped flatheads until 1954... Chrysler through 1959... Chevy always OHV... from start in 1900 onwards...
