New to Hot Rodders site building 1966 Chevelle 310
I've read some post about the 383 stroker engine on this website and was hoping for some guidance.

I have a 350 block that was decked to zero that is .030 over. I'm going to have to go at least to .040 because the pistons currently slap.

So I have this block that is ready to go and another block that wasn't decked standing by.

I have the RHS racing heads 200 runner Pro action. I also have the RPM Performern Air Gap intake manifold, high flow oil pump and water pump. I will use an electric fuel pump.

I hope to use either the 383 kit from White Performance kit number 4340 with either flat top or domed pistons or a kit from Skip White part number P3832P-.040.

I talked with Lunati and they recommend a .600/.600 lift roller cam.

Its a lot of info but I am also trying to achieve over 500hp/tq and still don't have a recommended carb.

With the exception of the heads, no part has been bought so please substitute if it will help attain my goal.

Thank you.

What are you thinking about for compression? You'll have to go decently high but i wouldn't take it past 10.5:1 if you want to stay on pump gas. I don't think you will hit 500hp. Not without using either race fuel of forced induction. I could be wrong, but 500 seems a bit wishful.

I wouldnt go much past 10.5:1 either,single plane might give more top end,600 lift cam is probably correct depending on the air flow of your heads? I would use an 850 holley double pumper and 1 3/4"
primary tubes headers. the engine will need to rev past 6000 so you will need transmission and gearing appropriate to your useage.

Op, if you really want 500hp i would go with a blown 355. You'll hit the 500 mark easily and driveability will be better since you wouldn't need a massive cam.

Thank you for the responses.

I don't want a blown motor because I want it to be a sleeper. I am looking into an AED 850, cam is .560/.565 and 243/251 at .050 duration. Compression is between 10.7 and 11.02. Will probably use Skip White's 383 stroker rotating kit but I can't get them to rerturn my calls so I started looking someplace else.

I have the TH400 and the 410 rear, intake manifold is currently a RPM Performer Air Gap but can be changed if necessary.

Thanks again,
