Welcome aboard Felix. sounding like a mild daily driver? TCI rebuild kit I am assuming. I would suggest some Stealth aluminum heads as opposed to sinking money into antiquated 906 iron heads. more details: what vehicle, what application, budget. do you already have the 383? better would be a 400 block with an offset ground 440 crank for 470 cubes & the external dimentions would be the same for fitment

I agree on not sinking money into those heads , but it may not be an option.

Everything you have listed is fine to use, do you already have the TCI transmission , if it's just a streetfighter it's nothing special. A basic rebuild with stock type parts and a shift kit, you pay the big bucks because you are paying for their race sponserships.

You really need to look at the pistons and heads to make sure you have enough compression. Some 383 pistons will give you extremely low compression especially on a 906 head.
Don't ask me how I know........

Agreed. You can overcome some of this with a cam that has a more aggressive lift rate. I think there are better options out there than that Performer RPM cam if you're using some ~8:1 Speed Pro flat tops. The Comp XE268 will work with power brakes and a stock converter. It will also preserve some of the low end you'll be giving up with the loss in compression.

I bought this set in summit Federal Mogul Premium Engine Rebuild Kits MKP-667E300 here is the part number I don't have any transmission for it . You can watch on summit thank you for your help You don't want that kit , if you have not bought it yet don't, it uses this piston which will give you barely 8.0 compression . https://www.summitracing.com/parts/slp-366ap30383 piston selection is horrible, the stock piston in the 69 383HP is .0025 in the hole , with the stock 906 the compression is barely 9.2 , not the 10.0 that chrysler rates it at. The TCI transmission is grossly overpriced for what you are getting, don't waste you money on it either. Contact John Cope/CRT and see what he can do for you .

The OP mentions money being a determining factor in the short term. That engine kit will get the car on the road inexpensively even if it isn't an ideal piston. Based on the parts list, I'm inferring a slightly warmer street engine is the goal. That can definitely be accomplished with smog pistons assuming the OP picks a cam that makes the most of cylinder pressure--and octane rating will be a complete non-issue.

No way is a Comp XE268 the right cam for an 8:1 383. The largest cam I'd say fit the bill would be Nughes SEH1016BL-12 http://www.hughesengines.com/Index/produ...mp;partid=30251Or Lunati Voodoo cam 10230700 Or Comp XE256H 21-221-4 Another thing is compression: Don't put a lot into the 906s right now, the Edelbrock E-Street heads at 75cc will put the engine right at 9.0:1. R.

Is that budget entirely for the engine build? Because that works out to a max of about $9000 US.
Which is a lot of money for a 383 rebuild.
I don't know what pr9cves are like in Europe but that would be a monster build here. A complete 440source stroker kit is $2249, rods, pistons, crank, bearings all balanced and ready to install,.
Another $1000 gets you a pair of all new aluminum cylinder heads.
That's less than half your budget and most of the hard parts done and new.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
