Re: 383 stoker

a 383 is pure SBC! meaning 1985 and older parts will work great if you motor fits in this catagory of year. some 85 and newer parts will work, but do your homework first. probably one of the easiest motors to build and work on.
a 383 is a .030 bore 350, with a 400 SBC crank. this motor can be a tork monster built on the cheap>> if done smartly.

EDIT: didnt proofread before I posted. a 383 is a .030 over bore with a 400 crank. sorry

A stock 4" bore and a 3.75" stroke will net you 377 cubic inches, bore that .030" and get 383 cubes, go .060" over and you're up to 388.

Re: 383 stoker

that may be true. lol but the block specs are what i was refering to. and I dont use a high volume pump. it sux 7hp from a decent 350 when a stock pump only takes 3hp and still get the same oil pressure. witnessed it on the dyno.

Re: 383 stoker

You may know this, and it was just a type"0". It is called a "STROKER" motor. This is because the stroke has been increased by using a crankshaft with a longer stroke. Case in point: A 383 is a 350 engine, that is bored over by .030", and uses a 400 crankshaft. A 350 has a stroke of 3.48 inches, where as a 400 has a stroke of 3.750 inches.

A 383 is a .030 over 350 block with a 3.75 crank. It's simple math. A standard bore 350 with a 3.75 crank would be a 377 just as onovakind67 stated.

Re: 383 stoker

phat69camaro,

383's are great motors...I'm biased because I run one. The 383 is a very popular hot rodder motor. It's kind of a mutt, but a good one. It was a way to throw some extra cubic inches at a 350 motor. They can be built to be major power producers if done right. Mine is a technological dinosour. 12.5/1 comp., JE forged pistons, H-beam rods, forged steel crank, (1960's) 461 Feulie Heads fully ported with 2.02/1.6 stainless valves, .585 lift solid flat tappet cam, Team G intake, modified 750 double pumper carb. It runs into my 7200rpm rev limiter like a raging bull. 11.9sec at 116mph in the 1/4 in a 3500lb 69 Firebird with full exhaust, and regular street 235 tires fighting traction all the way. And my motor is by no means a STRONG one compared to what people are running today. If it's built well, it should serve you well.

George
