500 horse 383 build

[generalme]

  A few years ago there was an article...may have been mopar muscle magazine or something...that had a 383 build. They used a 800+cfm Demon carb, Mopar M1 intake, a cam upgrade and maybe something done to the valves...If I remember correctly...they made anywhere between 450 to 500 horses. I started this project years ago...I have the 383, I got the M1 intake...but unfortunately ran out of time and money....that was 5 years ago. Does anyone know of this article/magazine or the specs...I forgot everything. Also, Its seems that my M1 intake is much higher than an edelbrock performer I currently have on it....will there be clearance issues with a large demon carb as specified above with a stock 69 charger hood?

hhhmmm I dunno if the M1 is same high as eddys rpm intake, but I can say rpm, 800 holley and 3" aircleaner fits good under the 69 charger stock hood...

Have the issue at home. Made 450hp, 383 edelbrock heads, comp cam,480, 490 lift. Compression was low I think due to the fact the owner thought the compression was 10:1 but actuall y more like 8.5:1. Pistons were down in the hole like .85 thousands.Performer RPM intake. TTI headers. Was in a white 1971 roadrunner and they ran it on a chasis dyno.
Will look it up tonight
