How much horsepower can a 400 small-block make?
How much horsepower can a 400 small-block make?
With timing and jetting maximized, the 400 managed to produce 458 lb-ft of torque at a still low 4,000 rpm, while kicking up the peak horsepower to just 401 at 5,400 rpm.
Can you make a 383 out of 400 block?
And at a glance, building the 383 seems almost as simple as mashing a toasted marshmallow and a piece of chocolate between a couple of graham crackers. A 0.030-over 350 block, plus the 3.750-inch stroke from a 400 small-block (versus the 350’s 3.480-inch stroke) equals 383 cubic inches.
How much horsepower does a 1970 400 small block Chevy have?
400 Small-Block (1970-1981) First-year 400 small-blocks were available in 265 and 330 horsepower versions. The cylinders of the 400 were “siamesed” and required steam holes in the block, cylinder heads, and head gaskets.
Can you supercharge a 383 stroker?
Add a Supercharger to a Well-built 383 and Get a Real Boost in Performance. Today it’s not uncommon to see superchargers finding their way onto just about anything short of a lawnmower. Blower companies offer bolt-on kits for virtually every application, be it an EFI-induced late-model or a carburetor-fed classic.
What is a stroked 400 SBC?
This is a stock style setup, featuring a 3.750″ stroke. This is a very mild stroker combination, using a slightly longer-than-stock stroke at 3.875″. The result is higher displacement and bottom end than stock, with a very good balance between low-end torque and top-end horsepower and RPM.
What do you think about the 383 Stroker?
Personally I like the 383 stroker, it has unbelievable torque for its size and the 400 block has siamese cylinders, some of the blocks had a problem running hot since there is no way water can get between the cylinders. I built a 408 for my Delivery. I know they say not to bore a 400 block over .030 but whats .010.
Should I build a 383 or a 400 block?
Now, if a 400 IS NOT available, and a person just cannot round up a good 400 block, either because of the cost, or, because a 400 can’t be located within a time period to meet a schedule, then building a 383 may be the only solution. My point was, if BOTH a 350 and a 400 are available, KEEP the 400 crank in the 400 block and build the 400.
What’s the difference between a 383 and a 350 or 400?
The 383 with 5.7 rods is supposed to build more torque…..My 350 is a 4 bolt…not sure if 400’s offered that. Never, under any circumstances, take a sleeping pill and a laxative on the same night !
What is the difference between a 350 and a 400 small block?
This happens because the 400 small-block uses a 3.75-inch stroke compared with the 350’s 3.48-inch stroke. Add in a 0.030-inch overbore and the displacement formula spits out 382.6 ci, which car crafters have conveniently rounded off to 383.
