It won't matter if you're not going to put good gas in the tank anyway.

Cam LSA remember you will be driving this car more than racing it.
A street motor has to do a lot more, well, than just run @WOT.

A closed exhaust system has a big effect on real Scavenging and what turns out
to be the best overall cam LSA. The cam LSA and the exhaust system have to work together.

yup a 220cc head will tend to want rpm.

post 1 you said you were looking for 500/500 and you want to use AFR heads?
There are many combinations and more power available. 1.3 hp per cube is a semi serious street engine,IE;500 hp/383
you also expressed the desire to use a hydraulic roller cam?remember I said to use a moderate solid roller cam.If you go to a hydraulic roller cam to make 500 hp then other items need to be stepped up a little to compensate for the hydraulic cam.

Now if you step up to 550 hp(easily done)that is 1.43hp/cube,you will for sure need the bigger heads(ie;220s)more cam.If you still want to use hydraulic roller then a little more cam still.

Instead of having 500 hp at 63-6400 rpm,you will need 65-6700 rpm,depending on final cam selection.
you have to decide where you like to drive and how you treat your engine.
In my case,my 434 makes peak power at 6500 rpm,first 2 gears I hit the rev limiter when I apply full throttle. Only real problem is dual 3 inch exhaust announces where I just was,,,

you need to decide on the heads you will use first.The heads will then get all the parts that match the build.Do you want more torque or torque at a lower RPM? My engine makes a tonne of torque,but the torque peak is around 4700 RPM.The effective rpm range on my engine is 3-6800, idle to 2,000 is fair then things happen in a hurry.The only time my engine is below 2,000 is when Ive stopped..With an automatic the converter choice is important.you need to decide that too.not a bad idea to think about converters/gears/engine RPM range for your application,,,as a package

For comparison,I use TKO 5 speed 3.50 gears,an engine that makes power to 7k.
A good thing about a solid roller,IE,mine,,,it makes peak power at 6500,but continues to make very good power to 6800 with little roll off in power(down about 25 hp @ 6800)

my original post,plus 9.4/9.5:1...I would use a callies dragon slayer crank,check weight of crank if you decide differently. Afr 195s with the cnc work. crower rods,wiseco forged pistons.get an sfi approved balancer like fluid.The block needs a good blue print,bored/squared/decked.For a street engine I would probably use 006 PtoW.Cam I would make room for 600 lift,just in case you step up later or move the cam back.You are on your own tuning F.I.,thats dyno time.Would probably want fuel curve at 12.5:1 at W.O.T. for a street car.Ignition curve TBD on dyno.headers should have 1 3/4 primary tubes with consideration for a 1 7/8 step if you plan to rev 6500 often.

383 stroker

Vinnie is right. Anyone can throw parts together all willie nilly and hope for the best. The best performing engines are ones that every component works with the others. You want 550 hp but seem decided on the AFR195 heads. Getting to your goal with those heads will be difficult due to their limitations. There are alot of factors that have to be considered when building an engine, such as how its going to be driven. Say we can accomplish your goal of 550 hp...can your clutch and trans handle it? How about the rear end? Anyway, Vinnie told you to decide on your heads, then select a cam to complement those heads,( roller preferably) , then select a carb and intake to match the heads and cam...then headers that will vent that engine. Brother, listen to what Vinnie is telling you...once you decide on certain components, he will walk you through the rest of the build with the best possible parts to match those components...ust dont be afraid to deviate from your original plan. I will be happy to help you as well, seeing Vinnie and I tend to agree on most things when it comes to stroker small block chevy's.

383 stroker

Although the best kept secret on this site is that Vinnie is running a twin turbo Volkswagon 4 cylinder diesel in his vette.

Nah...just kidding! Vinnie is running a beast of a stroker.

i found these builds what do you guys think ? the airwolf heads are to expensive i can get the afr heads for under 1500 i also would be running 10:7:1 compression and multiport fuel injections and 195cc street heads with one of these combos do you think id be over the hp and torque ratings they gave ?

IT DEPENDS

There are many 220cc heads that can make more torque off idle than some 180cc heads- volume doesn't mean as much as you think. Its all part of a package.

If you're going to buy an aftermarket head I wouldn't bother looking at anything smaller than a 195cc port, and a 220ish port would be around the max I would look at for a 350 that sees regular street use. Looking at a 245cc port is when it starts to just get silly.

The Assault Racing head (chinese) is a damn good head for the money (its super cheap) and can make over 500hp at a very streetable RPM.
