For a 283, DO NOT use heads meant for a 350, or even the 327 Camel Hump/Double Hump heads (unless you have some serious domes on the 283 pistons). The smallest chambers the Double Humps had, were the 461X castings with 62 CC’s; the rest had 64 CC’s. 350 heads could have as large as 76 CC chambers!

The stroke increases the rod main’s centerline diameter. The rod and piston have to travel in a larger diameter in the same engine rpm. This increases the piston speed, which makes the stroker pull more air at a lower engine rpm. A 383 has the same piston speed at 2,500 rpm that a 350 has at 3,100 rpm.

What’s the difference between a 383 and a 383 stroker?
It gets the extra inches from having only a larger bore, it still uses the stock stroke. A 383 Stroker is just the opposite, It uses the stock size bore but uses an aftermarket crank to get a longer stroke.
What transmission is best for a 383 stroker?
A 700R4 will be your best bet for an OD trans. It only has 4 gears, but GM has just recently started going with the 5 & 6 speed auto boxes, those extra gears would probably cost you a small fortune, and you’d need a PCM for the trans.
How do you tell if a 350 is a 383 stroker?
A 383 is a stroked 350 so the block will still look like a 350 block and have the same numbers. The only way that I know of for sure is to look at the bottom end of the engine. It will have to be ground for clearance and it might have markings on the crank if they used an aftermarket crank.

Add a Supercharger to a Well-built 383 and Get a Real Boost in Performance. Today it’s not uncommon to see superchargers finding their way onto just about anything short of a lawnmower. Blower companies offer bolt-on kits for virtually every application, be it an EFI-induced late-model or a carburetor-fed classic.
What are the benefits of a stroker motor?
A stroker is an engine that has been modified to increase the length of the stroke and therefore has a greater engine capacity. Its benefits are improved torque and power.
What is the biggest SBC you can build?
Also, 4.250-inch is probably the limit of the block’s capacity for overbore. By using the raised-cam block to accommodate a longer stroke, you can get the big displacement using a smaller bore so there’s more meat left for future rebuilds and so that you can use shelf pistons.
What is a 434 stroker?
Basically, the 434 is a 400 block over-bored . 030” (4.155”) with a 4.00” stroke crank. The block may need some clearance work. Definitely a small base circle cam will be needed to clear the increased stroke. You’ll have to use a lot of custom parts for use with a 434.
What makes a 427 SBC?
To come up with a 427 combination you have to use a 4.125 bore (stock 400) and a 4.0″ stroke crank. You can do it with a stock 400 block but you have to have it sonic checked to assure minimal core shift. It also reguires “stroker” rods preferable with cap screws rather than rod bolts and nuts.
