406 sbc vs 383.

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 383.1977Chad350. 927 posts · Joined 2004. #5 · Sep 2, 2014 (Edited) you can always do fuel injected 400. but the 400 will be cheaper when all put together unless you find a donor ls car or truck. Around where i live you dont find a 5.3 under 300,000 miles, with that many miles your going to need to rebuild.I am very happy with the throttle response also. I haven't tried a dual plane on it. With the solid roller and the 210 heads you 406 should really want to rpm. Mike. 70 chevelle. 420 sb combo - [email protected]. 405 sb combo - 11.87 @112.5. 307 combo - [email protected]. 68 chevelle 533 almost there.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.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.

And interesting enough, there are combinations of the two. Internal balance, for the harmonic balancer, external balance for the flywheel flex plate such as 87-95 SBC including LT1 and LT4 Opti-Spark engines. Pictured is a 1986-1997 Chevy 153 Tooth Flexplate with the external balance weight highlighted. You may also need a Harmonic Balancer.

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. “At first it sounds rather sedate but we ended up making really good power with it,” says Consolo ...This is a private listing and your identity will not be disclosed to anyone except the seller.

Also added a 1050 CFM carb (QFT with 4150 base). We expected 100 hp. In truth we got about 40. A good block is still weaker in the webbing than a 350. (not as much material) 4 bolts are weaker than 2 bolts. Pros- Your not racing it, it uses the same accessories as 350 except the flywheel and balancer, to the average joe you might pull it off as a 350. Cons- Has a bad rod ratio (1.48:1).

by Cris » Fri Aug 22, 2008 6:44 pm. Last months "Chevy High Performance" magazine had a very good comparison between several SBC manifolds. 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.

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.

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.Step 01:- Installing a Crankshaft. First of all, we have to purchase a 383 stroker crankshaft, 10.5:1 piston set, and rod. We have to note that adding more stroke to our engine can raise our compression ratio.

Those are the pros. 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.

Pistons with a 12cc d-shaped relief for the 350 and an 18cc relief for the 383 with a zeroed deck and a 0.041" thick gasket will put the comp. ratio at 9.7-1 for both engines. If you decide on a 383 a larger camshaft will work fine.A longer rod will give you much better performance than a 2.055-inch valve will ever get you. All said, you will not go wrong by opting for 2.055-inch valves over 2.02-inch valves. However, the same time/money spent in other areas will likely generate better results.

It is going in a 1989 firebird, probably ~3500lbs pretty easily with driver. As a 383 with the following specs, it ran a 7.85 in the 1/8th which should be around a 12.3 in the 1/4. It had a little rumble at idle, but nothing radical. The 383 was a mismatch, so I hope the 406 does a little better.Re: SBC 383 vs. SBC 400 (Jenny) I'd probably go for the 383 unless I already had access to a good 400 block. 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.As i said before, i'm on a 406 sbc project.
