There is an older mechanic here in my town with a Distributor machine, but he told me by phone that he can only spin point type distributors, he thinks, has never spun an electronic distributor but was gonna investigate if it can be done the same. Was considering just buying a new performance...

It seems like more cam and compression than a buddies 1969 340 4 spd car with stock cam, motor seems very healthy its just more of a desire to get into the RPM quicker, being an auto, and getting rid of the surge when cruising. i had begun to believe it was from lack of vac advance, the fuel...

so your suggestion of springs with perhaps a 3000 rpm "all in" @ 34 degrees based on the initial i can find that the motor likes, which is likely higher than the 12 degrees its at. Is there a difference to which side the lighter spring goes on? because looking at my present curve it seems to...

Ya, its all speculation unless your the builder, as i bought it as is, much assumption on internals, shop paper doesnt specify parts except "customer supplied" as i believe it was assembled by owner and the info came second hand to me.

I will try bumping up initial, will bring too much total. If it wants it, then i will have to figure out how to "limit" the total, still would need lighter springs in order to bring it all in by 2500? Dont have a welder for slots, not interested in FBO plate(cost to Canada and heard they can...

Yes i try for a 650-700 rpm idle in D, 850 in P. when i lower the P idle to 700-750 the motor still idles around 650 in D but shakes and sputters, but never stalls. sounds nasty tho lol.

I am not, just what the machine shop spec paper says, its old, "customer supplied" pistons. machine 001 C/R 10.5/ F1008 or could be E1008, smudged and 25yo paper. I just assumed a flat deck grind and was told it was "zero deck" compression so it required 91 or better, i use 94 from Chevron which...

RPM drop from P or N to Drive results in a 150 rpm drop and what i feel is "too hard" of a clunk into gear

Not sure

Rotor tower is cast color

Yes , I am thinking that , although its not a big cam, it still has lope and at 14" of vac it would likely need more initial. The "surge" is more like a stumble when cruising at moderate hyw speed or even at 30mph cruise, zero "surge" or hesitation when under throttle to accelerate, car does not...

Hi So i used an dial up timing light and "mapped" my distributor ignition curve, well, i wrote the timing curve down, not sure how to find a graph to "map" it? 1969 340, 10.5 zero deck, purple 276/284 .444/.453" , #2531894 heads, ld340 intake, mopar electronic dist with "oem black box" and dual...

Thats it, i feel the curve in my car is too quick, the reason i had to knock it down from 34 to 32 all in. That mechanical curve is why i am afraid of the vacuum can being attached, it came unhooked, i believe the previous dist tuning was for lighter springs and "all in by" a lower rpm than...

Thanks Mattax I have an isolator its thickness is 0.320, edelbrock 9266. I also bought some insulating and reflective sleeve for my fuel line from pump. i am also looking into some coated Dougs headers to replace the old low hanging hedmans that radiate super heat. Just havnt installed until i...

I am new to tuning my 340( ld340 intake, headers), unsure of what cam is in motor (more lope than stocker), unsure of actual comp ratio but its a 69 340 with 894 heads, electronic dist, vac advance not connected. Bought it like this. Doesnt hestitate but seems sluggish till about 3k, heard it...
