350...383 is a stroker motor, a 350 with a 400 crank and cam which increases the stroke and adds .3 liters of displacement.
That depends on what you put with it. Compression, heads, cam, method of aspiration. You could build one with 200 hp or 2000 hp.
You don't have to change the cam, but a cam that is perfect for a 350 may not be perfect for a 383. Cam manufacturers offer technical assistance to help you select the right cam for your application.
dont worry about your power hell your just a few hundred from having a 383 stroker dont stop now !! around 260hp+
A high lift cam lifts an engine valve by a higher amount than a low lift cam.
exactly the same as you would time a sbc...the cam swap doesn't change the way you time the motor...make sure that the plugs wires are ran to the right cylinder... standard firing order 18436572..... 4-7 swap firing order 18736542
Yes they will. The limiting factor of these heads are the valvesprings. You cant run anything over .470 lift unless you get a set of beehive Comp cam springs or get the valveguide machined to use a regular SBC Gen 1 spring. These heads stop flowing around .515 lift any more lift than that and it cant flow anymore through the head. These heads would work great on a 383 for towing.
vale springs dependon what lift your cam is . need to know what lift cam it is where can get the correct pounds spring if not can have one BIG HEAD ACHE.
EX CAM 2.5MM LIFT AT TDC INTAKE CAM 2.4MM LIFT AT TDC
you can make it a 383 stroker,add a bigger cam,its like a 307,its got a 283 block with a 327 cam that makes it a 307,you can't do much more to the 307 to get more power,because it has a short bore,you have to find other ways to get some power,its bored pretty much close to the max. There are all kinds of mods that you can do to get more power. A 383 stroker can be a 350 block with a different crankshaft and pistons, giving it more stroke, making tons of torque. A 283 block with a 327 crank ends up being a 333 after a .010 oversize bore. I believe you can make a 377 out of a 350 with a different crank and pistons too. 377 is the best of both worlds, meaning toy get more stroke, giving more torque, and you can also run it at high rpm for more HP. This is normally done with a 400 block but I am pretty wure that it can be done with a 350 block also, just a different combination of parts.
If you're saying that the lift is .470" with 1.5 rockers and you want to know the lift with 1.65 rockers, then .470 divided by 1.5=.313 lift at the cam times 1.65 =.517"
