1967 383 build options.

[dkbug]

Been searching through the forums for awhile and figured I would post up and ask about some of the expert opinions on a decent build on my 383.

It's a 67 motor (non hp) and I am wanting a decent weekend cruiser.

I purchased a 20/20 crank with 20/20 bearings for cheap, so stock stroke it is.
I'm not going to invest in upgrading rods and pistons seeing as how the ones in it are like new and in good shape, so I am keeping it stock bore. (to keep the build cost to a down low)

I saw the build they did on the stock 383 in Mopar muscle mag adding an intake, cam, and headers for a total of 455 Hp and 456 ft lbs of torque. Is the combo they ran basically as good as it gets?

Ok, I will get to the point now. What are some good intake/cam combos for a good low end motor.

Stock heads worth a port job?

Dyno sheets on the difference between stock flow and a ported flow on stock heads?

Basically my goals are to keep the build cost down to a minimum. College life sucks especially when part time jobs only pay so much per month.

I have $800 to spend, am I in the ballpark?

WHAT WOULD YOU DO?

Thanks in advance FABO

do the same as the mag did.

I would think very carefully on the exact cam to our base if your not following the build. Know the exact compression ratio of the engine.

I ask you, what gears and tire size will you be running?
Is a converter change out possible?

If you plan to alter the two above, then a different cam may be used. If your running stock gears and converter, your cam choice is limited to small in size. But nice power cam still be made.

$800 doesn't go far building a motor. You'll need to be very certain what you want out of it & what your gonna run with it.

Yea, you ain't kidding. I'd purchase the cam, lifter and valve springs for the job brand spankin new and search for the rest in the for sale area. Sell what I'm not using to off set the cost.

Dkbug, what do you have for it now?

do the same as the mag did.

I agree, if you are stuck with the 383, do as they did in the article. 800$ won't go far.

i'm including a quote from a guy named "Hutch" over on moparts. if i ever build up a 383 i'll do something like he did. i'll post his video underneath. basically a 383 11:1 comp ratio runs a 3100 car under 10 seconds in the 1/4... and has been running it for 5 years lol.
dont underestimate a 383.

I have a bit of an odd ball combination but it is a low deck deal based on a 383 so I thought it would still fit the thread. 4.280 bore with a short piston , small dome netting approx 11:1 compression. 6.860 MP lightweight Oliver rods , lightened stock crank with a slight decrease in stroke to 3.360" . MP Stage 6 heads with a small port ,MP 2.14 , 1.81 valves (3/8" stem) , MP 590 solid camshaft, Edelbrock victor 440 manifold with .080 cut off each side to fit the heads properly and a old carb shop 850 carb. This deal is 385 cid and seems to like shifting around 7800 rpm.
Its in a 3100 lb car and has run a best of 9.86 at 135.60 in good air through header mufflers.
Many don't believe its basically a 383 but thats fine. Its very mild , behaves well and has proven to be a great bracket motor for the past 5 years. I have another one of these im going to start pieceing together but I will increase the stroke to 3.600 as the small motor is lacking slightly in the torque department.

What kind of piston is that? specs?
Thanks Rem

Don't laugh too hard. I actually bought them from the friend of a mopar 383 lover who had passed away and left these pistons behind for his future project which never happened (he had the same idea as me I guess). They are Venolia pistons , .187" dome with valve reliefs , lightened in every possible way , .927 pins (very short but similar to todays lightweight honeycomb style pistons undercut below the oil rings for weight savings) and they were made in 1971!! They are very noisy as the running clearance is much higher than what is run with todays designs.

Here's a vid (in car) but its not great. Converter was way too tight and the list goes on. It was a few years ago and I really need to get a new video of it now.Still a 9 second pass in the heat of the day. http://www.youtube.com/watch?v=9K6ard18yo8

Moparlover. As much as I want a 9 second car, $800 won't do it. I kniw hutch's motor as I have done some research in the past and I plan to copy his build someday.

I have a new crank kit and rings already. I now have $760. I'm running stock pistons and rods.

I think I am going to make a new thread and show that an $800 comfortable cruiser build is possible. Anyone support this thought? This isn't the first motor nor will it be my last. Not to mention I'm all mopar.

I will collect all parts from ebay and forum members keeping the dollar on the low.

Oh ya, ill be running a dual plane instead of a single, upgraded converted (haven't decided yet) and 275 15 or 16.
