A used mag motor complete can be had less than your conversion.
I don't understand the interest in mag heads and not going all the way and running the mag motor. In the long run you will be better off with the mag motor as the cam will never go flat and you can take advantage of better profiles.
I agreed- you can pick one up for less than my conversion... But at the time I had no garage or equipment to get a used mag engine from the junkyard to my home, and then pull the 318 out of the 5th to drop it in. I could however swap heads without having to do any of that. The added plus- I wanted to see what all the fuss was about, if the magnum heads were really that good. Turns out they are.
To answer a question someone else asked- I got a smokin' deal on the Crosswind because everyone at the time was saying they were basically junk, so the guy I got it from sold it for $50 to get rid of it. Brand new, still in the box. Turns out they were wrong. One caveat and to be honest I did give him a factory iron 4-bbl intake off of a mid-70's 360 truck along with the $50. But hey cost is cost. The iron 360 intake was free to me- another friend of mine went Airgap and this was the factory intake. He just wanted it out of his garage along with some other 'useless' items. This is all horse trading fellas- if you can't wheel and deal you aren't going to build anything cheap. Might as well get out the gold card and call Summit.
OP, good luck with the build.
Enjoy! CC.

a $50-$100 magnum intake for a carb where can they be found? how do we get the fuel to the carb on the cheap with a magnum on this truck? these "little" things add up. the thread says "cheap 318 build" and as per moparts protocol we have the usual build a 360 or go magnum suggestions, soon it will be build hemi. we have ventured way off course here.
lifted85 if you want to swap heads, pull a set of 302 heads from an 85 up to 91 (premagnum) 318 car/truck/van in a junk yard. get a valve lapping tool(suction cup, very cheap), some valve lapping compound(also cheap) and lap the valves. there are videos on how to do this on youtube. its easy. put some 901 springs on using the stock retainers/keepers. call it done. another cheap upgrade, replace the heavy advance spring in the distributer with a light one(think ball point pen thickness) take the heavy spring to a hardware store and match up the length(cost is probably less than a dollar)
What are 901 springs? Can you elaborate Thanks
comp901-16 springs = single spring/damper are drop on spring with no machine work, uses stock seals/retainers and coves most stock/mild SB cams.
I have used them on 4 Lunati flat tappet VooDoo cams and 1 lunati 60710 roller cam, I just used another set with the Hughes whiplash roller cam, which is almost exact specs as the lunati voodoo roller cam.
nice bang for the buck for SB spring at 80$ a set
