383 Video

[BSB67]

383, "Hemi grind" cam (you know, those crummy, old style, slow ramp jobs), Performer intake (yes, not the RPM), 7000 rpm.   I was driving and using my phone so the video is not too good, but you get the picture.  This was in second gear, with the top down.

Love the sound of a screaming 383. Makes me want to take mine out.

Sorry to ask but, .474 - 280?

Are these also your "home ported" heads? Hard to judge the speed in the video but the tach is moving respectably quick.

Thanks BSB67 !!!!

Sounds good.

This motor has been together since 1981-ish and has the "modern" or "new" Hemi Grind - 280°/0.474" cam (4286631), as I wanted something smaller with less over lap (this motor had a lot of cam shafts before this time).  This was about the time Direct Connection started to offer this cam.  It replaced what was the old "Hemi Grind" which was a 284°/0.470" (3690214).  Kinda funny talking about it in the context of new and old today.

Yes, when I was a teenager, back in the late 1970s when that was done.

It does have good cylinder pressure, 200 psi-ish, and will not run on straight pump gas.  So that is why, at least in part, the motor is so crisp.  I could not do this video in 1st gear. And even in second, I had to start off fast going fast enough and the rpms high enough so the tires would not break loose.  To do it in third, which is a real blast, puts the car well over 100 mph.

This car is not as fast as the Charger, but is twice as much fun to drive.  Can't believe that I let is sit in the corner of the garage for 13 years without even touching it.

Very cool....that little motor buzzes up nicely. I'm impressed that it revs so effortlessly with a hyd cam. I guess the old school lifters are waaay better than the stuff we have on the market these days.

  love it. i want to see a better quality video with a co pilot filming.

I second that! Going through ALL of the gears. Looks like a little screamer!

Ron, I think it is two things, 1) the quality of lifters, and 2) fast rate cams are a problem if you want a decent rpm range.  The "hydraulic lifter" has always been the weak link, and the fast rate cams just make it worse.

I have Rhodes lifters in the 383.  Isky adjustable ductile iron rockers adjusted to zero preload. 

The car sat for 13 years.  Late last fall I dug it out of the corner of the garage, and pulled the valve covers off.  Guess what I found.  16 rock solid lifters.  After 13 years of holding various valves open at different lifts, not one soft lifter.  You could push and pull of the rockers as hard as you could.....no movement.  It is sad that you cannot buy parts like that today.

They really dont make them like they used to. My 383 went together in fall 2000/ spring 2001 with comp lifters. Same way. Sat for 3 years untouched at my parents and not a single lifter bled off. You have me blown away on the longevity, but it still shows what you can do when you choose the right parts. Cant wait to see more of that car on film.

The 383 magnum in my 'Bee was rebuilt in 1978. I drove it summers '79/80/81/82 for about 35,000 miles and parked it shortly after getting married in Aug '82. I fired it back up 7 years later in '89 and put the odd summer run to car shows on it for a few years. When I pulled it out of the marine container (after 14 years without looking at it) last fall it started on the third crank. No smoke, no knocks, ran and idled smooth. While getting it ready for blast and paint last week I noted that every lifter is solid, no loose / leaked down ones or sludge of any kind in the engine. Made when real steel was real steel I guess. One cracked open valve seal on an exhaust valve is the only noted test of time after 38 years.

Love the video !
