Search results for query: 340 cam

340 engine removed for repair . We've run it for the last 6 years not knowing too much about it. Solid flat tap cam & lifter. Thought I would learn more about cam but my searches come up empty.

"Same cam as 340"??

This is a OEM Mopar Small Block Cam Thrust Plate. It came off of a 1972 340, but should work on most Mopar small block engines. $20.00. Local pickup, or buyer pays shipping.

Howdy gurus. I could use some help trying to figure out a cam. It's available through a local guy and is clearly a purple small block cam. The box says it's a "Mr. Six Pack Grind - stock" from 1970. It's brand new in the box but the box is from Engle not Mopar. There is one number on the front...

the cam thing has been debated for many years now.. some say 340 cam and others say regular production cam. not sure anyone knows for sure..lol

Can't find the mopar purple cam 280/474 anywhere, I had that cam once and loved it nice idle and pulled like a fright train.what I like I was able to use stock push rods and rockers,just had to change valve springs comp 904.if I can't find my old cam what is a dead ringer close specs as the 280...

Is there a cam company that will grind a 340 cam to exact factory specs? I've looked but what I've found were close, I'm probably not looking in the right place. I'm researching on building a car for pure stock drag racing and the rules say that stock parts are mandatory except for the pistons.

I wanna to buy a P4120653 solid cam but the part number doesn’t come up at summit or Jegs. It comes up on a couple of websites but they look shady. Also what’s the difference between P4120653 and P4130653AE Thanks for your input Gannon

I have used the stock 340 cam with good results

Ode to the mighty 340, just add a cam, LD 340, headers and viola 400 hp. :rolleyes:....

The 68' 340 4 speed cam was a little hotter than the auto cam. Mellings used to make them

Ill try to keep it short. The car is a Dodge Dart Sport 340. I'm doing a refresh on my 340 (1969 engine), here is how its going together. 340 bored .030, zero decked, closed chambered SM heads .03 head gasket. I have a Holly Strip Dominator intake with a Barry Grant 750 DP. Looking for a dual...

340 cam, real ***** to work on, no 8 3/4, closed chamber heads, can't just throw headers on....

thats been debated for many years.. not sure anyone knows for sure unless someone actually pulled the cam and had it cam doctored.. many say its just a regular 360 production cam.

The MP cam is close to a 340 cam run it

Yes- before the 340 even existed- lmao! Special top secret “skunkworks” kind of stuff. Originally developed for the Chrysler small block in the marine / tractor market. That cam shaft was even in the Apollo rocket and went to the moon and back. Hahahahahah.

I am running a 750 Edlebrock on my 71 340 with a 509 purple cam with 3500 stall with a Trans go shift kit. My 340 loves the 750 Eddy..

I'm no expert but lots of changes. Isn't that cam a little long on duration? Cam timing is important. Did the 73 340 have 2.02 valves? Asking for myself as well. Stock 73 340 is a low compression engine. Stock 73 340 didn't have a square bore carb did it? A friend of mine bought a new 73 Dart...

In the near future I plan on swapping out 273 for 340. Exhaust will be upgraded eventually, but in the meantime for breakin can I use the factory 273 manifolds on the 340? Foresee any issues? Thanks Steve

Yep, The description for this motor reads like an early 340, except for the porting and mystery cam

I’ve always heard and thought of that particular cam as the upgraded 340 cam since it holds close to the stock valve lift but just has increased duration and by good bit. Lift is the only close area that the cam is in. The LSA is a 114 vs 110 and the duration picks up for an extra 13*’s @.050...

Didn't the little red express truck use the 340 cam?

"72 smogger"?? The '68 Manual trans. cam was a one-year only cam. After that all the 340 and 360 performance engines had cams loosely based on the 340 automatic cam- through the years part numbers changed and some specs were tweeked to aid in emission compliance, but were all closely based on...

The stock 340 cam had a 114 LSA.

Hey out there. I have a 360 with 340 pistions and the compression is to high. Needs 108 octane not to ping. Is there a cam i can use to lower the compression. 484 mopar cam in it now. Heads are from mopar in 1989, with rough port job from mopar and 2.02 valves. Do i really have to change...

I agree, but a 750 cfm carburetor is all a 340 needs in this combo. 800 was overkill for a stock 340. imo

The 340 auto cam was used. That's what Karl has said for years. @krazykuda and the Mopar Performance engine book stated that as well. It was supposed to have W2's as well. Little Red Express Cam Specs 268/276/44 .429/.444

EH1, which was basically the E58 with a 340 cam.

I am building a stroker 340 with a set of trick flow heads. It's a Molner 3.79 stroke with their H beam rods and Wisco forged pistons. The compression ratio is going to be 10.6:1. OTB Trick Flow Heads with Hughes 1.6 rocker arm. I have an Edelbrock air gap and Victor Jr for intakes (Any input...

When I freshened up my 340 I stayed with the Original 340/4spd. cam. I used Comp. Cam lifters .Knowing what I've learned now I would of resurfaced my originals. Luckily all went well. It's been 3 years now.
