406 sbc vs 383.

The problem with "More cubes" is that the 400 block can be more fragile than the 350 block. There's also hugely more 350 cores to select from than 400 cores. Now, if you're using an aftermarket block, no …Consider Part Changes to Lower Static Compression Ratio. Another alternative if you still want to run a blower on your 383 c.id. engine, would be to change parts to lower the static compression ratio. You should be able to run a 7-8 psi blower with a 9:1 static compression ratio and the engine might run fine on 91 octane fuel.There were two SBC "Street Dominators" the 300-36, aka the "Contender" Z-28 clone, and the original 300-1 single plane. Years ago, Hot Rod did a dyno test comparing the Z-28 intake, the Perf.

I looked at Promaxx heads, but finally bought the Blueprint H8002K heads, which are about the same price. I have standard dished pistons in a GM crate 350, so it limited the compression ratio I could achieve. I also have 4.10 gears, TH350 and stock 31" tires.

vinniekq2. a 383 is only 18 cubes more than a 355,yet a lot of people think its a magic motor? Long stroke engines have a higher piston speed than short stroke motors.If you build a 393 stroker you would likely make more power than the 396 stroker,because of what Valkyrie says about bore size and head flow.

This was one of the (unfortunately) rare times a car rag actually did tests over several manufacturers. They took a garden variety 500 HP 383 SBC and started swapping intakes. The dual planes were tested with a different (smaller) cam than the single planes. For the Edelbrock RPM Air Gap they ran tests with both cams.runn141 said: thinking of getting a set of dart aluminum 72cc heads. which would be better for the street 180cc or 200cc intake runner? the camshaft is an extreme energy 262 with a 469 lift. 64cc chambers and 180 cc ports would be the best choice with the XE 262 for anything less and than a 383.

The 383 is a bit more radical on the heads/cam combo but it still makes all of the power of the 377 but of course has a ton more low end grunt! The 383 runs the numbers with a 2800-3200 stall and the valvetrain doesn't take a beating. The 377 hit's it's best with @ a 5000 stall and shifts are closer to 7800 vs the 383's 7000 shift point.I've decided to have a 383 built for my 68 vert.

A 383 Stroker has a 0.030 bore width expansion over the basic 350, with a 4.00 bore. Installing a 400 crank in a stock 350 raises the stroke to 3.750. Every other dimension remains the same. And doing the math, you get a 382.6 figure; rounding it up gives you 383ci.when you calculate all the parts required to build a reliable 500hp-600hp SBC , then calculate the cost of building a similar power level in a BBC that in many cases can be built with more easily sourced, (like a stock 454 BBC vs a expensively modified 406 SBC)or even modified stock BBC components, you'll rapidly see why Id suggest building a BBC ...

The stroke length determines whether the engine is a 350 or a 383. The 350s use a 3.48" stroke, the 383s use a 3.750" stroke. Generally speaking the 383s use a .030 overbore vs the standard 4.00" bore of the 350, though most probably most "350s" are actually 355s which are .030 over 350s after they are rebuilt.
