Alright, so I've gotten enough cash to possibly start building a new motor; a 385 stroker. I've got a block that is fresh and ready for assembly. The kit I'm looking at will put me at ~10.8:1 compression with my current cylinder heads (Dart Iron Eagles 200cc heads with 1.6 rockers)..

so the question is this: is my new cam I ordered for my 355 going to be adequate for it? I haven't installed it yet, but I ask this because maybe I should step it up on the duration before I piece it all together? I have a 2500 stall converter from Hughes right now, but I will probably be buying a 3600 from Chris @ Circle D fairly soon regardless of which cam I use.

I essentially bought the Lunati 401a6 solid flat cam, but from Bullet Racing. Specs:

Solid, fair idle. Excellent Pro Street cam for 355-400 cubic inch motors. Needs 2500-3000 RPM stall converter, headers, 10:1 compression ratio, and 3.73 or better gearing.
•Advertised Duration (Int/Exh): 276/284
•Duration @ .050 (Int/Exh): 243/251
•Gross Valve Lift (Int/Exh): .518/.530
•LSA/ICL: 110/104
•Valve Lash (Int/Exh): .026/.026
•RPM Range: 2500-6800

Only difference is I had them grind it on a 106 LSA instead of a 110. Because this is a solid flat tappet, how would this affect the increased cubes from a 385? Would I be better off we going a step up or is the cam I have now perfect for it? This will be a street/strip motor. This is the 401b1 I was looking at:

Solid, rough idle. Good Pro Street or Limited Sportsman cam for 355-406 cubic inch motors. Needs 2800-3500 RPM stall converter, headers, 10:1 compression ratio or better, and 4.10 gearing.
•Advertised Duration (Int/Exh): 280/288
•Duration @ .050 (Int/Exh): 247/255
•Gross Valve Lift (Int/Exh): .525/.540
•LSA/ICL: 106/100
•Valve Lash (Int/Exh): .026/.026
•RPM Range: 2800-7000


My question is this: Is it worth the few extra degrees of duration to spend an additional $200? I ask this because I'm actually new to solids, so I have no idea how much that added duration will help in a 385 stroker.

Stay with the one you already have. Even if the $200 weren't a factor, I'd still recommend the same.
The stroker will handle that 106 LSA just fine.
