406 sbc vs 383.

This allows the use of most rods on the market without having to grind any material from them when used in engines with a 3.750 stroke crank, such as those in the 383 and 406 sbc engines, and this includes the Scat H-beam rods, as they usually have the worst cam to rod interference.Aug 27, 2010 · 4606 posts · Joined 2008. #3 · Aug 28, 2010. when. i was looking at the 377/400 thing ,, i compared them on Comps simulator ,, until you add alot of port flow ,compression and , alot of cfm in the carb dept ,,, the 377 beats it almost everytime on top , the 406 makes more torque at a lower RPM on the simulator. If you use small journal 327 rods on a 383 crank it is possible to offset grind the crank to get another 0.070" stroke which makes a 391 out of a 383 or a 396 if the engine is bored 60. I say, stay with the 350 and get a good set of heads and roller cam and maybe a small shot of N20.The 383 small-block has become incredibly popular in the small-block Chevy market. This is especially because the cranks are virtually no more expensive than a standard stroke 350 crank.

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.

The only expense increase is in the material choice, from cast to 4340 and on up the food chain.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.Most generally, and all other factors being equal, a long stroke small block like a 383 will make better numbers with a 106 LSA cam vs. one with a wider angle ground into it. Your compression ratio is suspect if you intend on running that much camshaft. You really need 12.5:1 minimum to really utilize a cam of these proportions.SBC CHEVY 406 421 434 DART SHP BLOCK 4.155 BORE SIZE FULLY MACHINED, 350 MAINS. Available $2,895.00. Add to cart.

I am building a 383 SB and was looking for some information on the pros and cons of using 6.0 inch rods as opposed to 5.7 inch rods.

I think that's a good happy balance between the 406 and the 383.a 3500 rpm stall for shure. I suggest two tunnel ram 500 Edelbrocks for ease of tuning and less sensitivity to change, MSD 6 or custom DUI (Performance Dist) if it will fit, full vacuum advance (40-45*) at idle, and a tighter lobe separation angle cam (106>108) of 225* duration. BTDT :thumbup: Like. J.The advantage of mopar 383/400 vs 383/408 stroker would be bigger bore size for better breathing and better rod ratios for less friction (hp/wear). Plus can be taking up to a way higher powerband (hp) if wanting to over stroker small block. The only real advantage to the small block strokers is size and weight if you care about that.Take care of these issues and a 406 will run just as well as a 383, but when you stomp the gas pedal you will feel the extra cubic inches the 406 has. 400 Pro s No if and or buts there is NO replacement for displacement: 350, .30 over, 3.75 stroke = 383 CI. 400, .30 over, 3.75 stroke = 406 CI.

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.Aug 21, 2012 · 383 or 406 sbc. a guy around my way has two blocks that have been through the necessary machining and reassembled what im asking is what would most of you racers go with the 383 is a fresh 30 over 350 block with a 400 cast crank external balanced with 400 rods forged flat top pistons.

I run an electric shift PG with a 5500 stall and pro brake, but the 406"er broke a rod bolt, so in went the 377" motor.
