406 sbc vs 383.

A smooth idle 454 & a radical high rpm 383 can theoretically make the same power, but the 454 will drive like a stocker. As for looks, the amount of attention a big block Camaro gets is amazing. I see this at local shows quite often. A typical big block will also cost 25-50% more than a small block.I do a review of the AFR Enforcer SBC head.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 ...The problem with "More cubes" is that the 400 block can be more fragile than the 350 block.

A 406 would be a good motor ...

My last 406 had the Victor Jr., 950 carb, and a 3500 stall. It was super responsive and drove everywhere on the street. The new 383 has the Performer RPM, 850 Quickfuel carb, and a 4100 converter. It is very responsive as well and running AFR 195's on this one, last one had the AFR 210's. 72 Nova 383.

Re: 383 vs 400+ Engines 03-07-03 04:59 PM - Post# 191042 In response to The_Stupid_One Somehow I fail to see the 383's making more power than the 400's.

Re: Super Victor vs RPM Airgap Dyno results SBC. by bigcam406 » Sat Apr 09, 2011 3:59 am. i recently saw a manifold shootout article where the air gap rpm beat the majority of single planes tested in average torque and horsepower.the small block used was a 383,brodix ik200 heads,roller cam,pump gas deal.the test range was from 3-7 grand.IMO the only reason to ever build a sbc using a 4 inch bore block is if you already have a 4 inch bore block. 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).The 383 small-block has become incredibly popular in the small-block Chevy market.

I've weighed both in a '67 Camaro and the difference was 2740 lbs.(sb) vs. 2895 lbs. (bb). The car was a gutted race car. The small block has way better gearing than the BB Camaro so it should accelerate much better and be a couple hundred, or more, pounds lighter.Jul 9, 2019 · On this episode of Engine Power, we start and finish Stage 3 of our Small Block Chevy build.

The 383 Stroker engine is fitted primarily to boost a vehicle's thrust force. 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.

Similar HP, but the LS3 drives 1000x better. The 350 to get that HP was pretty radical with a high stall converter. The LS has a high stall converter too, but it has OD with a lockout.
