406 sbc vs 383

Engine 3: Torque 400s 383ci. 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. The only expense increase is in the material choice, from cast to 4340 and on up the food chain.

Now that you said that, I would go with a gen 1 sbc. I am all about the ls engines. They are quiet smooth and dont seem that radical, Compared to a gen 1 sbc at the same horsepower rating.

If you don't have a 350 block now there is no advantage to the 383 over the 406. Be careful of the lure of large displacement small blocks. It begins to get very pricey after you go beyond a 3.800 or 3.875 inch stroke, (415-421 cid).But even in naturally aspirated trim, the 383 Stroker was no slouch. Equipped with CNC-ported AFR 195 heads, a healthy Comp hydraulic roller cam, and Edelbrock dual plane intake, the 383 pumped out peak numbers of 538 hp at 6,200 rpm and 506 lb.-ft. of torque at 4,800 rpm.

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 ...Now that you said that, I would go with a gen 1 sbc.

The 23 extra cubes of the 406 (a 400 block with a .030 overbore like the 383) should yield a nearly proportionate power increase but I don't think it would be that noticible a difference unless measured on a dyno or at the strip., a 383 is a .030 over 350 with the crankshaft of a 400 small block with it`s main bearing journals cut down to fit the 350`s smaller main bearing saddles. so the bore and stroke is 4.030 X 3.750, this is why it`s called a stroker, since the stroke is longer. Since the stroke is longer it makes more torque., The problem with "More cubes" is that the 400 block can be more fragile than the 350 block.
