I seem to have had a bizarre accident with my engine and it appears a rebuild is in order.Those 5.7 LS1 engines had a bore of 3.898 and a stroke of 3.622 compared to a 4 inch bore and 3.48 inch stroke in a traditional small-block 350. To make a 383 stroker LS, which utilizes a 3.905 bore and a 4 inch stroke, you either need to hone an LS1 just a touch, or take a 5.3 and bore it out .125.Series One 185 SBC. (Sold in Pairs) $ 830.00 - $ 1,431.00. The 185cc series 1 heads are perfect for that budget build. Making great power at a price that cannot be matched. Machined and assembled in the USA. Dyno results show 20 to 35 hp gains over the competition.

In my humble opinion the 400 is a better build for the Buck for all around use, and a 383 will run just as hot as the 400. I've built many of both, but it seems that the Stump Puller puts in on the Mouse motor with a lot less rev's. But you can't go wrong with either. :beers: The Cincinnati Kid.The original small-block Chevy weighs in at 190-pounds. And while the LS aluminum block comes in at only 115-pounds, the iron units are 215-pounds. The LS's extra weight is related to the block strength, which is much more robust than the small-block from years ago. The LS has a skirted design, which means the sides of the engine extend down ...

The chevelle is a 3.08 and the camaro has a 3.90 with similar first gear ratios. 406 needs more gear than you might think. Obviously depends on a cam but a performance build you really want to see a 3.36-3.73 gear assuming a tire size in the 26" area. The 454 is a serious hoot even with 3.08s.

I'd never build another sub 396 ci motor again. Your not going to beat the 434/427 small block with a 377 if you have correct gearing. Lets say that motor "A" 377 makes an average of 500 foot pounds of TQ from 3500 - 7500 and Motor "B" 434 makes 520 lbs from 2500 to 6500.I realize this is a older thread but I wrote this years ago. Holley HP carb inflated CFM numbers Oct 23 2005. Holley is misrepresenting their HP carb sizes, a HP 950 is really a. 830, a HP1000 is about a 870 if measured the same vac as a 47-- series. The industry standard for cfm ratings was 1.5"Hg vac for a 4 barrel.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 ...

That's pretty much what we see with the 383 vs. 406 units. Our pump-gas 383's average approximately 475 HP and our 400's come in around 575. The problem basically with the 400's is coming up with cores. Many of our customers opt for the aftermarket blocks on the 400's. These blocks are also worth some add'l HP. Thanks, Gary in N.Y. P.S.

Why would you betray america and put a commie crank in your engine. (Chinese production quality is terrible!). In case you didn't know 355 is a 350 bored 30 over so the rotating assembly is the same and not really worth your dollars compared to a 383. 10.0:1 is fine for aluminum but go only as high as 9.5:1 with iron, I have 9.3:1 with 67 cc ...If you leave the cam the same, you will see very little gain in HP, but it will make peak TQ and HP sooner (about 200rpm). If the heads are the restriction now, that'll also keep it from making any more HP, and it'll nose over sooner. Mike Jones. Jones Cam Designs. Denver, NC.The main difference between a 406 SBC and a 383 SBC is the size of the engine's displacement.

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. Feb 9, 2012 · A 383 has a 400 crank as you know. A 421 needs a stroker crank which costs money.

Just my one time experience.A head with 180 or 185cc intake runners will work well on a typical 350 Chevy street engine that makes 400 to 450 horsepower. If it's a 383 stroker, you can probably go with 200cc intake runners. Putting a higher flow head with 220cc runners on a relatively stock 350 would be going in the wrong direction.EXPLAINING A RACE WINNING 550+HP 383 STROKER #383stroker #383sbc #dragtruck #chevyk20.22556 posts · Joined 2007. #2 · Dec 16, 2009.
