I'm confused as to where this EQ heads only support 470 lift out of the box? That info seems to be false. I bought a set of bare heads through Magnum Mopar, with the cam he recommended. My stock heads were cracked. Took it all to the machinist, where he double checked the valve grind, and then...

Damn trailbeast you might be a genius! Do you have a build thread for this car?

Have a 5.9 to drop into my Duster, what is the biggest cam that will work with the factory injection?

Been plugging away on my car recently and I am now charged up to start on my engine. The budget is starting to squeak! So I am considering looking for forged .30 over 340 pistons. Then for connecting rods, my 1st machine shop didn't want to work with my stock rods, wouldn't even look at them...

I know this will make some puke, but I had to do it.

I have a 71 or 72 340 intake taking up space in my garage. I will get around to listing it one day, or you can give me $25 plus shipping, save me the listing headache! :)

Any difference between a 71 and 72 stock intake? My intake is number3614025. Also where do you find the casting number on the crank? Better see if I have any more surprises. My blue late 71 block has orange J heads with 1.88's, I swear I will puke if I discover a cast crank! The parting lines...

So after really spending some time comparing the pics posted of a stock intake and the massaged one, was there much benefit to be had carving up the plenum? By the way, you guys are turning me to my stock intake. Guess the performer will be for sale soon. I'm going to throw that mopar crank with...

69 Cuda that is some really good info. I may look into massaging my stock 71 intake. Besides it is good for the sleeper look!

Thanks, the TQ is why I am so hell bent on going against the grain. I won't give up my TQ for love or money. I have had this eddy for years, with intent on using it, then the 340 fell into my lap. I am getting close to just throwing in the towel, and getting the damn air gap!

Does anybody have credible test comparisons or know of a source. 71 340 intake vs edelbrock performer.

Thank you for all the ideas. Unfortunately the Milodon oil pan and related parts cost me $6-8 bills. I promise nobody will give me more than 1/2 even though it sits unused new in original pkgs. hence the not throwing away good money after bad comment. I did gain some useful knowledge though. I...

In need of some tech help outside of my circle of knowledge. First allow me to preface this question with 2 criteria... I do not want to throw good money after bad. Meaning I need to try and use parts I already have as opposed to just buying something else. Second, I do not want to leave easily...

Well so much for my pipe dream of rings bearings and gaskets! Not to mention my now confirmed hunch that my 915 heads are in fact small valve! Cam and lifter valley are all clean and loose! Two cylinders got water in them! Time to start smart shopping! Modern lightweight pistons and valves here...

Finally brought my 340 home after a year. It is a 71, 915 heads. Well it is froze up, so clearly my dream of a hone, bearings,cam and gaskets is no longer viable! The 915 heads are most likely 1.88 valves. My thought it to put a light piston in it and rather than spending the money on 40 year...

I have a stock 71 340, planning on 3 season daily driver use weather permitting. Going into a 71 Duster, 833od, 3:55 rear. Comp XE268 stick, and the stock TQ. I have a Performer intake. Will this intake be holding this engine back? Also considering a Torker II. Open to other suggestions so long...

Bout sums it up. Street car, spirited back roads, heavy braking, on and off ramps, occasional auto cross. Do I really need that Milidon oil pan or am I just trying to make myself spend money, that might be better used somewhere else?

Like it was made for it! In fact it was, there is a pirt mismatch on a 340/360, but the 318 is good to go!

Anyone??? Wanna put it in a stock 71 340. Gonna keep the TQ, and slap on a Performer intake. Cam card says it will run 1800-6k, duration of 110* and lifts of 488 and 491. Doesnt say anything about needing headers, says 2200 stall converter. Moot point with my gears and 4 gear, it will cruise...

Wow you guys sure got ugly.... :). You guys have indirectly helped me out, yet left me still wondering somethings. I did learn that the 340 piston sticks up above the deck. So that is where they got there compression. Every stock 360 I have ever seen are waaaaay down the hole. Like I said...

Thanks guys...all of those thoughts have crossed my mind! I have seriously considered posting the vin and dumping it. The money would certainly buy what I still need for a 360, and I do have 360 knowledge! For years people have always contended that the 340 was by far superior. My thought was...

I just spent 850 and a case of beer for a 71(?) carb to pan, with complete front end, no manifolds. For $500 hundred i would have fallen over myself trying to get the money to the guy! nice score by the way!

Hey guys, I've been a 360 man since I had my 1st one built back in high school. I have spent the last 20 plus years absorbing everything I can about hot rodding 360's. I had settled on a .30 over flattopped, eq headed, magnum rockered, performer intake and Tq carb. The cam was still up in the...

Over the course of a few years I have accumulated a pair of 360's, a set of late magnum heads, and then just recently a complete 340. Now I have been in love with the idea of a mag/la combo, and have been a 360 man my whole life. So what donI do? Do a mag headed 340? Mag headed360? Leave the...

Is 800 a good price for a complete 340 air cleaner to pan, in running condition? Come out of a 72 b-body. That is the word on the 340 offered to me. Most impressionable car I've ridden in was a buddies 73 340/4 gear Duster with a cam intake and carb. Really has me thinking.

It is amazing how fast an engine can spiral down into the abyss of high dollar, bragging rights, etc etc. I just tore down my "26k" rv motor yesterday, it gave me no signs to make me think it was anything but a low mile engine! No cylinder ridges, bearings all pretty, journals all clean and...

Thanks guys...I really have been thinking about that cam. I'm not sure it is in my best interests...I am not looking for all out max hp, but rather near OE reliability and daily driver capable. Hell didnt the 380 horse magnum crate use a 509 cam? I guess the roller just gives you so much more...

Hey guys gonna start building my engine soon. I know the stock La rockers are pretty good, they may not be accurate enough for some of the hardcore, but they can be plenty stout and reliable! Had them in a 360 years ago with a .509 lift cam and spun it to 6000 rpm all the time, with no problems...

Sorry gentlemen...blew that one didnt I....yes it is a smallblock, a 360 in particular. I dont have heads yet, kinda debating those also...rhs, eq, mopar perf, etc etc. I cannot find a magnum engine in my area for love or money, so the plan was to use one of my LA 360's probably leaning towards...

Hey guys not gonna start building yet, but I wanna start looking. If you were gonna do a homemade direct port injection EFI, what manifold would be best? Then to throw another wrench in it, need to be able to keep a/c, and fit under a stock Duster hood! Thanks, Dan:burnout:
