platinium 215 or 330

[stroker383ci]

should i take 215 or the 230 intake runner for a 383 stroker ..anyone know if the 230 fit for a bore of a 4.030 or only for a bore of a 400 ci and more ??

Going to need alot more info than that.........cam, compression, intended use, rpm range, intake, carb, hp/tq goals............................................. .......Go to chevy engine setups and check out the thread 180 or 200s. There is alot of info there about a certain 383. Not sure if it applies to yours.

[stroker383ci]

well i got a solid cam 520 540 3700 stall convertor 373 gear ratio air gap intake for the moment .. flat top piston and i wanna run 64 cc chamber..road and track race .. 6500 max rpm

[lun40119]

I would use the 200 or the 215 ask Don and Bill, they will have opinions, both are professionals, and would have much more information than I do.

[stroker383ci]

well i already have sportsman 200cc and i know its not big enough so doesnt wanna go for a new set with 200 cc

[lun40119]

Like I said.....it is just my opinion. I have the 215's and are very happy with them. Perhaps check with one of the Dart techs and see what they tell you. Otherwise wait til around 500am tomorrow and see what Bill says. I would be willing to bet that Don will have an opinion as well........

How did you come to this conclusion.............I had a set of Sportsmans too, and they seemed to run out of steam at 6000 so I dynoed before purchasing heads. Turns out that the cam that should peak around 6800 quit at 5800 and maintained, it never really dropped just maintained hp numbers. so I tried the 215's and gained in hp and torque in all areas of the pull from 3500-7500. Good luck.

I sent you a link to the two different dyno pulls on youtube................it is in your pm folder

Lun has a very good combination. You ought to take what he has put together and clone it into your 383 combo. I think you can do what you're wanting to do with 215s. But the 230s are not for what you're wanting to do imo.

Need more info on your combo. Lift numbers only aren't enough. Need all the cam numbers, crank type, rod type, carb, weight of vehicle, and rear suspension type. Why the limit on the 6500 rpm?

How long have you had your old 200s? Why do you think you're running out of head? Your intake could be the reason for that.

Let us in on more of what you're running and we can give you alot more help.

Thanks, Don :cool:

Your 200 cc heads are quite capable of supplying any and all power needed for your application you have now. Your shortage in RPM is a simple fix. Most out of the box flat tappet stuff is just getting by at best. @ 6000 rpm, your valve train is flopping around like a fish out of water. The intake you have won't pull above 6000 if that. Your camshaft does not give enough lift let alone proper duration. If your going to run a flat tappet camshaft, your going to spend a little money on lightweight and much stronger vavle train parts. You have good parts, just not the right package. This is what I would not want to happen!. You install a 215/230 cc head and do not pick anything up and then talk about us! If you are serious about this combination, (don't waste my time), get in touch with me @sales@awesomeengines.biz. I will point you in the right direction that you need to go. Without getting the complete package together to work together, you will always be wondering why your stuff is down in power.

well my friend run those iron egal 215 with almost the same set-up that i have but its a 355 ..well for the weight its a s-10 short box ...ill let u know thnx really apreciated ..cam is a etreme energie 520 520 solid from comp cam

[lun40119]

Have you checked leak down with the old heads, perhaps that could be a problem. When is the last time you had a valve job done on those heads. If you are looking to just buy the new heads, get the 215's that will leave you room to grow:D

[lun40119]

I did see differences below 5200 in both torque and hp, however the real difference is above there especially 6200 to 7500. I have a 3000+ chevelle with a loose converter and a transbrake, and 4.56 gears. The cam is over .600 lift with 268 duration at .050. For what I do with this combo I love the heads.........Don and I have talked with some porting and a good comp valve job, I could probably be doing as well or better with the 200's. But next winter there will be a new rotator being intalled that the heads will be killer for. It is difficult when on a working mans salary to find the right parts for any given combo, there are two ways to look at it...........one is if it is a work in progress leave room for growth, and two, if you are going to build it and leave it alone forever, build it for now. Bad 67 has a similar cam in a 355 with the older 200's and loves it. I think it runs well into the 11's and is a street car. Perhaps PM him for more details on the combo. Bill has a point with valve train parts.........don't get cheap, I am still makin power when I hit a wall. Springs at 7500. Good luck,

ps what parts are in the bottom end.....Don asked a couple times and I don't think you ever answered him.

[stroker383ci]

cam is 244 252 at@50 ..282 290 advertise 110 lobe seperation 2400-6800 cam rpm specs.flot top hyperothetic piston . gm connected rod .. with the sportsman head i run 12.00 flat on a 1/4 miles .... my friend did 11.60 with a bigger roller cam so i think i'm not that bad with that set-up.but i'm sure with the new style combustion chamber and new generation i could go faster .. i think i will go for those 215 my friend got those iron egal 215 and it run pretty awsome for a 355 ... he almost beat me on 1/4 ... i got a bit more mph with my 383 but only got those sportsman heads 200cc

[want-a-be]

I think you need an open plenum intake, and a lil more cam....mostly lift...maybe another 10 deg of duration.

I agree with Bill. Work on the package you have now. If it's not right, putting more head to a bad combo isn't going to fix it.

I do agree that the new pro 1 heads are alot better then the old sportsmans. They are worth the upgrade to imo.

Why the straight plug heads. You have a rule against the angle plug heads?

Don :cool:

[stroker383ci]

nothing agaisnt them but i read that you better run straight plug for flat top piston ..if i'm wrong let it me know ... ill order my heads tomorow so ....

The Sportsman II heads were good when they were made, so were GM 461's, I had a fully ported set of Sportsman II heads and the same engine combo with as cast Dart 215's was making the same, if not more, HP on the big end and my old Sportsman II's were fully ported with large runners, extensive work on the Sportsman II's

[stroker383ci]

thnx for all the info ...the 215 cast iron platinum heads are awsome vs the old 200 sportsman ... new thecnologie give better hp...:rolleyes:
