406 sbc vs 383

The 383 is meant to be a higher compression engine, using either the 5.7" or 6.0" rods. 400 uses a 5.5" rod. The less oversquare you have in an engine, the more torque that's produced. (Oversquare is bore vs. stroker, for instance 4.030 x 3.750 (383) vs 4.125 x 3.750 (400) vs 4.000 x 4.380 (350), etc) 400 heads also have steam holes in between ...

Howard's 110885-10 but, most part told it opted for the lunati for many street use reasons and Lunati suggested this to 383-400. The 110 lsa will probably not produce vacuum enough for my power brake so, i would ...For enthusiasts on a tight budget, a 383 makes a lot of sense, as the largest bore a 5.7L aluminum or 5.3L iron block can handle is approximately 3.905 inches. When you match that bore size with a 4.000-inch crank that requires minimal clearancing, the end product is an easy-tobuild and affordable 383-ci short-block.Dyno'd a 383 stroker equipped with Whipple Supercharger's carbureted small-block tuner kit.

Years ago, Hot Rod did a dyno test comparing the Z-28 intake, the Perf.

To me, if you can make the same power with a 6,000 rpm 406 and a 7,000 rpm 355, then the 355 is more likely to break bottom end parts due to rpm. Now, if you can afford all the best in bottom end parts, then this may not seem big.Here's some pics of my old setup. So really to build a high-rev small block, need a good flowing set of heads (I was running ported Dart II heads), a solid camshaft can't be beat for high-rpm durability, single plane manifold and matched carb (of course matched valve springs, pushrods, lifters etc).If you're looking for a good, solid 383 stroker kit, check out the Scat Crankshaft and Rod Assembly Kit.

Of course, 6500 rpm requires good heads, intake, cam, exhaust, gears, and ...If you're looking for a good, solid 383 stroker kit, check out the Scat Crankshaft and Rod Assembly Kit.

The cons are you lose a LOT of torque in the mid-range and HP right across the useable RPM scale the wider the LSA. Consider this: Joe Sherman built a 383 for Chevy Rumble magazine some time back that made an incredible 540 HP and 523 ft/lbs torque using ported RHS Vortec heads with 1.94/1.50 valves. The cam was a 236° hyd ...Just look at the heads on a big block compared to the small block. 3) if there is any bit of core shift, you WILL grind thru to the water jacket on a 396. 4) more parts options with a 383 (especially pistons). So, the verdict for me was: to go with a fully forged 383 with a good package. Aim for optimum cam and heads.more displacement tends to result in more torque and as a result potentially more power. if a 302 makes 1.5 hp per cubic inch, thats roughly 450 hp. if a 383 only makes 1.3 hp cubic inch, thats roughly 500 hp. Id also point out that with current after market components, the 383-406 can make exceptional power.

Garry.After testing Arties engine, I'm convinced that the solid roller 383 has more potential than 500hp/500 lb/ft still at a streetable rpm. I'd like to do a 393 with an aftermarket block 4.155 bore and a 3.625" stroke; the XR274 roller cam and 2.08" valve AFR heads. I think that's a good happy balance between the 406 and the 383.my experience with sbc vs bbc. when mildly modified, if you have say a 400" sbc (406-434) and a 400" bbc (396-427) If both engines make the same amount of hp, say a 500 hp 434 sbc and a 500 hp 427, the small block will build more torque than the big block. that contradicts most all beliefs about sbc vs bbc.The LS ended up costing about $1400 more than the 383, but it made significantly more power. Had we made different choices, the scales could have tipped dramatically in either direction. At the end of the day, we proved to ourselves that the good old small block Chevy is still a viable performance engine that looks just right under the hood.This 383 stroker small-block Chevy assembled by Mike Consolo at QMP Racing Engines peaked out at just over 500 horsepower and produced 430 lb-ft of torque or more throughout the entire dyno run-all on pump gas and with a respectable idle.

To make a 383 stroker LS, which utilizes a 3.905 bore and a 4 inch stroke, you either need to hone an LS1 just a touch, or take a 5.3 and bore it out .125.383 Stroker. -5cc flat top pistons. w/ 64CC heads (pro comp aluminum) estimated compression from Eagle (bottom end) is 10.7:1.

These plugs are a gasketed, .750" reach plug.

There's a 400 out there that you may not know a lot about until you bust it down. A 383 option has been thrown out there and you say you are on a TIGHT budget. That being said, I'd stick with the 350. That's pretty much what we see with the 383 vs. 406 units. Our pump-gas 383's average approximately 475 HP and our 400's come in around 575. The problem basically with the 400's is coming up with cores. Many of our customers opt for the aftermarket blocks on the 400's. These blocks are also worth some add'l HP.

A 3000 stall limits the car. A 4000 to 5000 stall would be needed to get the most out a car. Old parts and combos can be faster than they were when they were made. Just saying.I have a 7500 rpm 383 ci and now I also have a 7000 rpm 427 ci small block. I'd never build another sub 396 ci motor again. Your not going to beat the 434/427 small block with a 377 if you have correct gearing. Lets say that motor "A" 377 makes an average of 500 foot pounds of TQ from 3500 - 7500 and Motor "B" 434 makes 520 lbs from 2500 to 6500.Here are a few good reasons why we think the 427/434 engine is a better choice than the 383 or 406 engine. The 427/434 will accelerate most medium to heavy cars dramatically quicker than the common 383's on the market. The main difference between a 427/434 and the 383 is that the 427/434 torque comes in much lower.The original small-block Chevy weighs in at 190-pounds. And while the LS aluminum block comes in at only 115-pounds, the iron units are 215-pounds.
