Why is a 383 better than a 400?
The 383 has a better RPM range, with lots of low end torque. The 400 is a great truck engine, and if done properly, can be a great car engine as well. No_Dice was right, most of the overheating problems these engines has was because GM was using too small of a radiator for the engine.

Can I use 305 heads on a 350?
305 heads on a 350 will raise your compression a good deal, maybe even too much for pump gas if you have flat tops or domed. I would go with 350 heads if I were you. If you have flat top pistons a set of 350 heads would be best.
What year is the best Chevy 350 engine?
L31 (2002) From a purely technical standpoint, the most recent version of the Chevy 350 would naturally be the best of the bunch. Marketed as the “Vortec 5700” engine, but known internally by the moniker of L31, this engine was used primarily in GM vans and trucks until 2002.

Is a Pontiac 400 a good engine?
Because of its place in Pontiac’s most brutal and outlandish muscle cars as well as fighting the good fight into the era of smog-choked, low-compression lameness, the Pontiac 400 remains one of our favorite V-8 engines.
Is a 400 small block a good motor?

How much horsepower can a small block Chevy handle?
With a stock block, using after market crank, rods, pistons, bolts, heads, etc., you could expect a small block 350 to make upwards of 450 HP and for it to reliably handle upwards of 550 – 600 HP, and a big block with the same aftermarket components to make power in the 500 to 600 HP area, and be able to handle upwards …
Why is a 327 better than a 350?
In the vehicle, it’s more of a matter of “gearing” than revs. A 327 with it’s shorter stroke would need shorter gears so it can GET to its revs, where a 350, with its slightly longer stroke and more torque output will pull a little taller gear than the 327 will.
Will SBC 400 heads work on a 350?
RE: 400 heads on 350 block 400 heads on a 350 block is a great way to increase your midrange and top end power. The swap is a direct bolt – on deal, you just need to be sure to use 400 head gaskets when you do the swap.
How much power can a stock 350 crank handle?
For small-blocks, a safe limit for a cast crank is 500 hp and a maximum of 6,500 rpm. With big-blocks, their bigger mains will handle 650 hp. We’ve seen cast cranks in turbo motors take over 2,000 hp, but we don’t recommend it.
Which is the best LS engine?
What engine is best for an LS swap? In short, the best engine for your LS or Vortec swap is the one you can afford. Sure, we would all love a shiny new LS3 crate engine from Chevrolet Performance or a rebuilt 5.3L long-block from Summit Racing, but once we crunch the numbers that’s not always possible.
How much HP does a cam add to a 350?
Replacing the 2G with a Q-Jet and intake alone can be worth 25-30 hp. Toss in a mild cam and cylinder head upgrade and the power gains really start to add up.
Will 327 heads fit on a 350?
They are perfect for a 350. Both the 327 and the 350 have a 4″ bore so they like the same heads. Old heads like that will have softer valve seats, so if you want them to last a long time, you should either replace the seats or run leaded gas in the engine.
What is the best Chevy small block engine?
The 327 L84 remained the most powerful Chevrolet small block production engine ever until the quad-cam LT5 came out in the 1990s. And it was the most powerful naturally-aspirated single-cam small block until the arrival of the LS6 engine in the early 2000s.
How much horsepower can you get out of a 327?
Rated at 375 hp, the fuel-injected 327 was a high-winding screamer, as satisfying to drive as any big-block. At the other end of the spectrum, the 327 was also offered at much more pedestrian power levels, as low as 210 hp (gross).
What did a 400 small block come in?
The 400 small block Chevy was produced from 1970 until 1977. It was originally installed in big sedans and wagons, but later found its way into some trucks. I don’t believe it was ever put in the Chevelle or Camaro. A co-worker has a very healthy 400 in his ’88 Corvette.
Is a 400 small block better than a 350?
A small block 350 and a 400 have an identical block design. Most accessories will fit either engine. The major difference is found in the casting numbers and the way they are balanced. Most 350 cubic inch engines are internally balanced whereas the 400 engines are not.
Is a 4 bolt main better than a 2 bolt main?
