I paid $350 for a complete 1999 5.9 Magnum from a Dakota R/T, in running condition. It has 80,000 miles, no sign of blowby, some coking on the inside, a full quantity of slippery dark oil in the pan, the full serpentine setup less A/C compressor and the magnum exhaust manifolds. I bought an airgap style polished intake used for $100. The rest of the package will come from the original LA 360 in the car and some new gaskets. That's my definition of on a budget. Hopefully it will be the equivolant of a 300 hp magnum crate when it's complete. Why pay for machining when it's still good?

New hemis are 10.5 compression 205 thermostats and run fine on 87 octane with very short duration cams and brittle pistons. Magnums have better chamber and being stuck on 91+ octane is not a big deal. More compression means more efficency and makes up the differance in price. I would shoot for 10 to 1 with magnums and that is conservative. The LD 340 runs out of steam at 6500 on a 340 and a touch less on a 360 if you had a regular performer you would shift the power down a tad but really not much. It will start makeing power around 2000 where even factory converters are just stalling any how. Get a small tube longest length you can find or some early magnum ex manifolds.

That probably has more to do with having aluminum heads and advanced ignition/timing controls than anything else. I would pay money to see that kind of a setup not detonate on a carbed motor.

10:1 on an iron headed motor with a short duration grunt cam is NOT conservative.

Here again the guy has the LD340. Why spend the money for another intake when this one will work fine. Sure it has a little higher RPM rating and performance but there is nothing wrong with its low end performance either. As for in the first post the poster also states that he is thinking of putting on an Airgap in lieu of the LD340. No point in that, there is so little difference in performance (if any) that the swap out would be money down the drain. Very probably get the best low end out of the OEM cast iron intake of the standard Performer which is not much more than an aluminum version of the cast manifold.

I'm sorry,no need to feel bad. Lot's of things are possible and I've tried alot along the years but when giving advise to someone I would rather give advice that works 100% of the time than info that has much less chance of success.
No way you are going to give advice that will work 100% of the time. You aren't God. None of use can or will claim to be 100%. We all do our best but but in no way can we be as you claim, 100%..

The point is it's the combo! It doesn't mean a thing that you could get away with something if everything falls into place,I know from experience,not reading a magazine and false assumtions. The poster is putting this in a truck! Not a much lighter A body. I don't think Spending the higher price for 91 octane is at all logical for the application. I built 360's with near 11 to 1 comp using magnum heads in the mid 90's and yes I agree they will tolerate slightly more comp I won't tell someone building for THIS APPLICATION that it's the smartest thing to do,Period.

I am speaking from experience also - dating back into the mid sixties and forward to present. You don't need a bunch of compression or a lot of $$$ in a 360 to make it work and work very well. Been there many times. A realtively stock LA360 can be made to pull real well and still be a very dependable daily driver without a bunch of high tech workings. A stock low compression engine and stock heads will work good along with good RV type cam with valve springs to go with it, intake and carb and good free flowing exhaust system will do wonders and not have to mortgage the farm to do it.

A stock 5.9 Magnum IS the 300 hp 360 crate motor. Check the part numbers. Cam, crank, heads, and everythign else is the same. Add your own intake and go. Get a 5.9 Magnum. Add a carbed intake and electric fuel pump. Hit the road. If you want a little more pulling power, you can swap to an RV type cam but that's optional. If you really want torque, swap in a real 5.9 (read: Cummins) and drag all the gassers sideways.
