HOW DO YOU MAKE MAXIMUM TORQUE WITH A SMALL BLOCK CHEVY? JUST ADD CUBIC INCHES! 383 STROKER BUILD!

HOW CAN I MAKE MORE TORQUE FROM MY SBC? SHOULD I BUILD A 383 STROKER? HOW MUCH POWER DOES A 383 STROKER MAKE? WHAT IS THE BEST CAM FOR A STROKER 383 CHEVY? IS A 383 BETTER THAN A 350 CHEVY? DO I NEED A BIG CAM IN MY STROKER? WHAT HEADS SHOULD I USE ON MY 383 STROKER? IS A STROKER A GOOD CHOICE FOR TOWING? CHECK OUT THIS VIDEO WHERE I COMPARED A STOCK AND MODIFIED 350 BUILD TO A 383 BUILD TO ILLUSTRATE THE EXTRA TORQUE AND POWER OFFERED BY THE STROKER COMBO. THE GREATTHING IS YOU CAN ADD A LITTLE MORE CAM TO THE BIGGER MOTOR AND STILL HAVE ALL THE DRIVABILITY AND POWER OFFERED BY THE EXTRA CUBIC INCHES.

My father, four decades ago, always said "Horsepower sells cars, but Torque wins races". Not a racer myself, but the cam in my 325 Dodge Hemi puts the peak torque right where I need it for passing on the highway in my '33 Coupe. Gotta love a Hemi.

Nice. I built a 381 (only 0.020" bored over) and made 511hp and 492tq. And that's with a 650 speed demon. The throttle response is awesome. This way, if you like the power of a wild 350, but you don't want to lose out on the lower speed tq, build a wild 383! You get back the lower speed tq, plus a bit more higher speed hp. Great combo, especially with 4.11 gears for the street! Let's just say I have fun on the street and never even wound out the engine. Granny shift at 5k and she boots! One day I'll open her up

Usually a 112 lobe sep. Works with 283, 110 a 327, 108 a 350, 106 with 400, depends alot on combo, such as valve size, rpm range, street or track, etc. But this is a better than most magazine or book cams with all ground on 110 lobe separation angle, also dial it in,dont trust gears !

Chevy guys really used to be stupid about this. The nitrous guys would use heads with giant valves (2.08/2.10" etc.) on a 383, robbing the crank from a 400 SBC. They should have been building 377 destroked 400s or perhaps a 406, for less bore shrouding (flow). A 383 is a torque motor and well suited to heavy cars/daily drivers/trucks on motor. Built a 388 (.060" over) for a 1960s P60 (cab forward 2-1/2 ton chassis) for a friend's ramp truck. Had so much low end with Promaxx 180cc runner heads and a RPM intake that he had to put a Brownie-box behind the 4spd trans and in front of the 2spd differential. The 327 was turning 3000rpm at 65mph, so I put a circle track cam in the 388 for a lot of torque (tight LSA) and it turned out to be a beast at even 2500, so hence the o/d unit.

But even though it’s a cheezy low compression 350, I can rock a 28 foot flatbed trailer full of firewood with my 3.08 gears and 32 inch tires. Peak torque is at like 2000 and it still makes excellent torque at 1500.

One day, I’d love to see someone build an engine to produce maximum power in an rpm range that people actually drive at. I’m old and slow, and rarely rev above 3000 rpm’s.

[@richardholdener1727]

I think you are confusing the needs of "people" and your own needs. People watch this channel to find out what makes more power. The vast majority of enthusiasts don't run their performance motors below 3000 rpm when accelerating.

[@nutsandbolts432]

@@richardholdener1727 you are correct. My needs are not the same as people’s wants. Just as people describing their daily drivers as race cars. Most people need engines to do things like idle, and make vacuum. It’s cool to see an engine rev to 8000 rpm’s making 1000 hp, and if you have a dedicated track vehicle, great. 2 terms foreign to most people that would build an engine is duty cycle and overall power. Maybe I’ll make a video about those 2 terms that are absent from the automotive community in the next engine I’ll build.

I wonder what max tow torque is possible with cheapish 400 sbc. I'm open to vortecs and tpi and maybe even cheap boost. But, honestly I think I would prefer it naturally aspirated, reliable, and hope for good MPG. All I want is that + max torque.

Does it make more sense to put a 350 crank in a 400 block, or a 400 crank in a 350 block? Just curious. You get more cubic inches, but you have to make sure all the rotating stuff doesn't hit the block, and use an external balancer (and flywheel?) in one case, and in the other case, you have the block with the siamesed cylinders so maybe cooling is a worry... Just curious which is "better?"

[@richardholdener1727]

most don't like to deal with Siamesed bores and steam holes-so 383 is more common unless an after market block is used

[@dannytravis7118]

I don't dislike the 350 engine I've had very good experience with them. But I've always wanted a 383 because I believe that if you're going to spend the to rebuild spend a few extra bucks on a stroker crank. I think scat used to sell a 383 kit that was almost a bolt in deal. It had cast steel crank and was 3.68 stroke and needed to have a. 040 overbore to make up for the smaller stroke crank. But it didn't need the extra clearance that 3.75 crank does. I don't know how much they are now but it was like 1150 dollars for the whole bottom end. Crank, rods,pistons rings and bearings

[@cuzz63]

Like one of the comments... If you're going to spend for a crank, rods, and pistons to do a 383. I would rather just change out the rods and do a 406. Almost the same amount of money, no clearancing issues and with the right cam, more power everywhere

[@markgarland4532]

I drove a 383 powered ‘71 Nova daily in the 90s and it was phenomenal. Horsepower may win races at the racetrack but torque is what you want on the streets. Small displacement engines need to be rev’d to be enjoyed. A fat torque curve will put a smile on your face at 1/2 throttle. I have built hundreds of engines and that 383 is still my all time favorite. Planning to build another in the future.
