What should my ignition timing be?
That is typically 15-35 degrees before TDC (top dead center) of the power stroke depending on the engine speed. Best power is achieved when ignition timing is set to fire the spark ahead of time to reach that peak pressure at about 2 degrees after TDC.
How do you set the timing on a 440 Mopar?
To make sure you are in the ballpark, set timing at 10 degrees BTDC by loosening distributor clamp, and slowly twisting distributor. Then, take engine up to 3000 rpm, and adjust timing to about 35 to 36 BTDC.

What is the difference between a 383 and a 383 magnum?
there isn’t any outside differences between the 383 and 383 magnum so there isn’t anything to worry about there. big block engines from the factory used a valley pan cover which was also the gasket between the intake and heads and it is held in place by 3 bolts and a plate on the front and rear of the engine.
Why is a 383 better than a 400?
The 383 has a better RPM range, with lots of low end torque. The 400 is a great truck engine, and if done properly, can be a great car engine as well. No_Dice was right, most of the overheating problems these engines has was because GM was using too small of a radiator for the engine.
How much horsepower can I get out of a 383 stroker?
That combo would probably make around 465 hp and nearly 500 lb-ft, but at less rpm. But never mind that. The point here is 502 lb-ft at 4,700 rpm and 500-plus horsepower from 5,700-6,200 rpm….Hot Rod’s Proven Recipe For A Simple Chevy 383 That Knocks Down 500 HP And 500 LB-FT.
| True 383 Power | ||

What transmission is best for a 383 stroker?
What is the best transmission for a 383 stroker? – Quora. Chevy made some great transmissions. The 4l80e is arguably the best, though not the easiest to hook up electronically. You would need to buy a transmission module.
How can you tell a 383 from a 350?
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.
Is a 383 the same block as a 350?
there is no difference. It takes a 350 block and 400 crank to make a 383.
Can I use 350 pistons in a 383?
If you use 400 rods (5.565) you can use 350 pistons. That is absolutely correct. A 350 with the normal 5.7in rod, or, a 383 with the shorter (5.565in) 400 rods will use the same piston. A 383 with the 350 style rods (5.7in) requires a piston with the wrist pin hole a little higher.
Are stroker engines reliable?
A few years ago stroker motors weren’t very reliable but with testing and redesigning now they are almost as reliable as a stock motor as long as you treat them right.
How much HP can a stroker kit add?
So, as a given rule, the more cubic inches an engine is, the more power it will make. However, the horsepower output will largely depend on the overall combination you are using. We could take a 500″ short block and with stock heads and a mild cam, it might make around 450-475 horsepower.
Is a 396 a good engine?
The 396 is a good revving engine, so you’d want to run a steel crank so it would live at the rpm you’d have to run it to make HP. And probably a roller cam, as flat tappet cams in big blocks have a nasty habit of “going away” relatively easily.
