383 build

Thanks! I'm going to do some more research. From the info here I have a good start for a plan. I know my 6 pack intake is not the most efficient but I like nostalgic stuff and tuned right it shouldn't hurt me too much.
 
youngguns dart was/is running 11.7's at 112 with the rpm head and small solid cam. I think he's running about the same with the trickflows.

I'm pretty sure HR did the intake shootout and included a 6 pack intake on their dyno mule 383; and while it wasn't the greatest thing since sliced bread, I recall the phrase "Mopar guys rejoice" as it performed well considering some of the past issues they've had with 6 pack intakes. But, looking purely at the numbers, you could realistically expect to achieve similar numbers with an M1 or RPM intake and a well tuned 750 carb.

Is your 6 pack already complete?

Oh, I certainly wasn't telling him to ditch it--hence the reason I asked if it were complete, and to put a finer point on the question, serviceable...multiple carbs and the pieces to go with them get expensive pretty quick...

The crux I picked up out of both of those tests was that unless you just gotta have every last ounce of power or torque or your combination is so far out of whack it won't run right (or the intake is unserviceable), what you already own is probably good enough--even an old DP4B or tm6

It's all ,good..He has an good bottom end ,a usable intake tract,all he needs are good heads.What'zs not ,to like? I certainly couldn't put that engine together,what he paid for it.....
 
Unless you actually KNOW how the bottom end is..... Your taking a chance.
You could roll the dice. If it starts to rattle after a while, you can rebuild it then. Or rebuild it now.

If you take it apart, the condition of the bearings and crank need to be OK. I would not exspect perfect.

Your cam choice will be limited to valve lift with the Pistons not having valve reliefs.
 
Actually, having done so, it is possible to cut some small valve reliefs in those pistons.
 
IQ, is this an easy job for the average guy to do in his garage? And where would one get the tool for the job?
 
If I recall correctly, he did that on a their junkyard diplomat 318 and eventually coaxed 370 out if it.
 
Isky rents the valve relief cutter,IIRC....Hughes too,I think....
