how do i find the timing on my 383 400 hp stroker motor
375 hp
That depends on what you put with it. Compression, heads, cam, method of aspiration. You could build one with 200 hp or 2000 hp.
It depends on the components that comprise the motor. The horsepower range can peak at around 450 hp with similar numbers for torgue, but can go as low as 350 hp again with similar numbers for torgue. Again, it depends on the parts use to manufacture the motor.
This is a null question the 383 is a block so you need to have more details to find out the approximate HP of an 383 is a 350 stroke out so stfu block that anyway 383 can have many different range of horsepower my 69 camaro drag car have 650 hp with a 383 but it have alot of bolt on's
No. the combination of larger displacement and an extra hundred HP will cause it to be too lean, a stock tpi will not do 400 hp. there are plenty of mods you can do to get it to work, check this FAQ, http://www.customefis.com/faqsite.html
about 425 to 500 hp
The 1978 El Camino was NEVER available with anything larger than a 350 CID motor from the factory. The horsepower ratings for these motors ranged from about 160 to 180 depending on the model. The "383 stroker" is a non-factory motor that is usually based on a 350 block that has been overbored and then equipped with a crankshaft with a longer stroke. Horsepower ratings for such a motor can range from 250 to over 500 depending on other engine modifications (camshaft, cylinder heads, intake manifolds, injection or carburetion, etc).
You have to start out with a 350 Chevy engine for bolt main ,boarded over 30 change the crank case Pistons and rods if done correctly you should have 600 hp not 420
that all depend on what you want to do with the car, if you want it for the street I would go with a 3.55 gear and for the track a 4.10.
