I didn't realize the link to Rapid Motorsports didn't work because of the extra period...here it is again:

Rapid Motorsports seems a bit pricy... Cmotorsports or Tbyrne seem to offer better deals.

 

ok, I'll take a look around and put together a list. I'll post it up here to see what you and the others think. Maybe someone will know of better places to get certain parts.

bam!

 

Wild1,
What is the difference between a "Hot Cam" and the crower cam that you suggested earlier?? Will different cams produce different amounts of HP...or does it just affect where the power band is and how the car idles? Do hot cams produce a idle that's too rough for a daily driver?

 

The Hot Cam is the LT4 Hot Cam that was made by GM. It is very steetable and mild/moderate for a 350. It will be very conservative for the volume needed for a 383. You could put it in there, and some have, but it is very mild and you will not be gaining the benefits of the extra volume.

The trick is the dynamic compression ratio. Targeting it between 7.5-8.5 is the sweet spot. This can be done with intake and exhaust timing, duration, and overlap.

The Hot Cam which is made by GM was intended for the volume of a 350. It will work, but to be redundant is will not optimize the volume of a 350.

What is lopey for a 350 will be mellowed dramatically in a 383.

 

Will I need to get new injectors as well?

 

The 383 with heads, cam, and the increased volume will require an adjustment. There is a fuel injector calculator on the web which I have saved on my home computer. I'm remote in Chicago for 3 weeks and will not be able to access the address. I'll see if I can find it via www.google.com tonight.

When I was doing my calculations, I needed 42# Injectors. But that was for a 383 w/ 11:1 compression and 100 wet N2O shots.

With your 383, you should be getting somewhere around 430 HP / 455 torque... +/-... you will need a fuel pump and should upgrade the injectors. However, without the program I couldn't tell you if you need 36#s or 42# injectors. Stock injectors are 28#s FYI...

 

The SCAT 9000 series crank will take over 700hp.

I'm at 478 hp at the motor right now using it.

I've never had a bad experience with Nu-Tek and dealt with them several times. I've made several big dollar purchases from them. Always rapid and courteous service.

No clue why you guys had problems.

Also I would not recommend an LT4 hot cam for a stroker app. Its a generic cam. If you're going with nitrous you might want to look at a custom grind nitrous cam.

Or else look at what kind of setups other stroker guys are using and what kind of power they're putting out and emulate them.

 

SCAT says their 9000 series crank will handle 600 hp (called on the phone). However, I cannot discern if it was RWHP or FlyHP. My guess is RWHP.

I have not heard anything bad about Nu-Tek.

 

Jersey boy,


How long have you owned your fbody?

As opposed to most, i would say going blown, or if yo uwant to go radical, turbo. esp if it is going to be a daily driver.

But at any rate, when you are getting into the engine, and increased horespower, you will have extra expenses involved, ask Trey, =) hehe.

Take your budget, multiply by 3, and that is how much it will run you in the end.

You will be laying all that power down, and will want to use it, did you budget for a Tranny rebuild, and rear end? what about the basics, full exhuast, headers back?

You will be doing bottom end, so might as well do top end, heads, cam, what about springs, rockers, pushrods?

Just something to think about......

I am also in jersey, close to you actually, In East Windsor.

Bottom line, if you want daily driver, might as well go for a mild blower for now, till the engine blows, then when it does, do a full rebuild for a blower, swap out the pulley and run higher compression.

 

I've owned the car for 5 years and a few months now. Had it for the last year of HS and I'm about to graduate college. As for the extra expenses...I'm well aware of them. It always takes more time and more money than you expect when doing modifications. I baby my car...with the occasion had accel...here and there, but nothing serious. I've never taken it to the track, or even reved up and dropped the clutch in a race. I don't plan on replacing the rear end until a little later...or maybe after it finally breaks...which would probably be after I start taking it to the track if that ever happens... Also, as I have posted in earlier, I already have the full exhaust done...and a bunch of other smaller mods. I'm just looking to breath some new life into the car. A sort of fresh start...with a newly rebuilt engine and all. Wild1 suggested going with the Heads and Cam mod first instead of the stroker, which is a great idea. But I figure...i'll just save a little more and do them both at once...

 

If you can do it all at once, the better. You are doing the right thing by asking first. Since you are planning on doing the 383 all at once, then you can get the best cam for your 383 application and port the heads to match the cam specs. You'll be much happier.

Stock ignition should be fine.

Fuel pump may need to be upgraded along with 36# or 42# injectors. The actual number needs to be determined on a program.

Have fun
