I have a pair of 393" strokers and a custom 410" stroker, all using Scat crankshafts.
The 393 is a good choice, but for a true streeter, I'd probably recommend doing a 383. As for heads, go to www.ausfordparts.com
for a set of AFD 2Vs and get a Weiand Xcelerator (single plenum) or any of the good aftermarket dual plenum inlet manifolds. Stay away from anything with the Edelbrock name on it regarding Clevelands at this point...the only exception is a Torker 4V, but I probably wouldn't go with a 4V head on a pure streeter that is intended to be a nice crusier/driver.
The biggest thing to note is that the Scat cranks (and all others, unless custom made) have a Windsor sized front snout, which will want a Windsor dampner or you can bush/shim the snout for the larger Cleveland dampner if you want.
Unless you already have all of the parts, the hottest deal going is a Clevor using an aftermarket block with Cleveland mains. Basically, you want to get the large bore Dart or World block, bore them to about 4.155-4.185 and then use a 3.850" stroke crank in a 9.5" block. This will put your oil rings above your piston pin and give you a 418 CID with a 4.155 and 424 CID with a 4.185.
The AFD 2Vs will easily handle the flow you need for a street RPM (1200-6000) big-inch Cleveland.
I would use the Scat 9000-series crank, as you don't need the extra strength of a 4340 crank for a low-RPM street engine.
I would use the 3.750" stroker crank in a 9.2" Cleveland block. In both combinations, I would run the large chamber AFD 2Vs and flat tops with extra large valve reliefs. That should put you at or near 10.5-10.6:1 compression, which should run well with 91 octane unleaded crapola fuel. You'll probably want to use a 750 DP. I might try one of the "Street Avenger" carbs to see how it works, as it will get better fuel economy.
What you want in a street car is a torque monster. Anything with 400+ foot pounds of torque is going to make your car feel very strong and pull on just about anything else on the street. A 383 or larger Cleveland/Clevor will easily make 400 TQ with good heads and an appropriate camshaft.
Speaking of camshafts, once you determine where you're going to be with your block, bore and stroke combination, give Mark Mckeown at www.mmeracing.com
a call and have him grind you a custom hydraulic roller. In fact, you can call him and he can hook you up with everything that you need.
Personally, I'd build a 424" with a set of AFD 4V heads and a Funnelweb with an 850 DP and a fairly big solid roller camshaft and "just live with it" on the street. It would make about 650 HP and about 570+ TQ...however, it wouldn't be as sweet and nice as a more mildly built engine. As it is now, I have a factory block/4V heads 357" in my F100 with a solid flat tappet camshaft and a Torker inlet...a 424 would really move it's heavy arse!
