Ed- sent you a pm.

thanks

I have a 67 coupe that [I] considered running years ago, but was informed by a known engine builder that its a hard combo to make competive. I considered making the mods to make appear as a 68 so I could run the 340 combo, Bought a 74 duster that was complete and just kept the cuda as a street car

I investigated running the 340 combo as that is what is in the car now. But the heads I use (w2) are not legal. A noted head porter suggested I find a set of 576 heads to use if we build the 340. I put out a few wtb posts with no results. But was given access to a bunch of 383 blocks, heads, cranks, valve train parts to use. So I thought I better start asking the right people.

The 308 heads flow almost as good as the 576 heads after a good porter gets a hold of them they will flow just as well.

Thanks
I do have access to several sets of the 308's. I will follow up with that.

Years ago, there were two such cars that were both pretty successful in SS/IA with 383's, but they might have been later models with T-Quads (if the 383's ever had T-Quads).... dunno. One was the Dave Smith (ProTrans) car out of California, and the other was Dave Boertman's , who may have won a Championship with that car.... maybe not. I just remember reading that it was fast...

At any rate, both were VERY competitive, if my memory serves me correctly. But, I think they both ran mainly in SS/IA, not J. Dunno what that was all about; maybe the HP factors were different then, or maybe they just didn't like the idea of ballast, but they were tough... both of them.

Hope this is accurate and that it helps some..

If you want to have a fast 383 or 440 with the AVS, the man to talk to is Steve Wann. Dave and Greg Smith's car ran the later 1971 version of the 383 engine with the Holley Carb.

Don Little would be a good resource.

[Jeff Lee]

I responded directly. Watch the 383 in '08 in Stock. That's all I can say....

[bsa633]

not knowing what year or body this apply to...but Don Little is the man on 383's it seems...but his is a holley also!

Thanks for all the replies. I now have a few real places to start asking some questions. One thing that I am concerned over is rumors of index changes. I am guessing that at the divisional races if you can't run the index your dial is going to be the index.

Forgot to thank Jeff Lee. That is exactly the type of info I was looking for.
