    I'm trying to find this camshaft for my 69 318, it appears to be a great option for me . I guess I'm just trying to find some good product sources as I get into my build . Thanks

    If you want a Hughes cam call Hughes? They’re the only ones selling their stuff I think

      I don't know a lot about the Hughes cams or any other cam for that matter but according to their website, they're designed for the lower compression 318 engines 1972 and up. 69 318's have higher compression and about 80 more horsepower than 1972 and up lower compression 318. Definitely check with them first. There was something on their website about needing to use race gas if you have a higher compression engine. The only reason i mention this is becasue i have a 69 318 and was looking to do the same.

      One plus is that you already have 80 more ponies than a 72!

      Here's a chart with mopar engine specs.

      They went from sae gross hp to sae net hp in 1972. Gross hp does not have any accessories. Not a lot of difference from 69 to 72. A little more... probably.

      It’s a pretty knarly cam; headers should do a lot with it. Slightly higher stall converter would be good

      Where you hear about it? Uncle Tony? Stuff he recommends is what my shop instructor use to preach

      http://www.hughesengines.com/Index/...V2hpcGxhc2ggTXVzY2xlIENhciBDYW1z&partid=30170

      hughes has a recurved distributor to go with the cam; you can do that lots of ways, but it seems kinda nice that’s it’s ready to go if you’re new to it.

      what are you looking to do with the car?

      Are you looking just to replace the cam or do an engine rebuild?

      Will need new lifters and valve springs if it’s a cam swap.

      Not sure if the stock heads and pistons, will handle that lift; folks will chime for sure...

      Also welcome! Very sweet ride you have there!

      Most important thing is to match components; lots of folks here to help with that if you need it

      my 383 claimed compression is also 9.2:1 but the pistons were .030” in the hole (I think) and I used a .040” head gasket.

      With compression calculator it’s pretty easy to figure these days; estimating I’m around 8.5:1

      not exactly what .474” purple in mine wants... same with the stock ports

      am still deciding what, if anything, to do about it; future tall dude problems

      To choose the right cam, you kinda NEED to know the actual compression; only way really know is with the head off.

      see how much the pistons are in the hole, if they are dished, confirm combustion chamber volume, etc.

      Oh man I didn’t know 318 stock cams were so mild.

      240 248 advertised duration, .373” & .399” lift 40A33D32-5B3F-42DF-942C-5A997C6B642E.jpeg CA345A6C-2AE0-4065-9EB6-6677A87E735B.jpeg

      It that engine has the original timing gears you’ll want to replace that ASAP before pushing the engine at all.

      they have nylon coated teeth that break off, and the chain could skip a tooth and bad things can happen

      Was just to make it quieter

      it’s what took my coronet off the road before I got it

      Just my $0.02

      If all checks out good...and your pistons are not dished and less than about .05 below deck.....

      Lunati voodoo 701 or 702...great cam...closes early...builds compression...more modern design..and speaking of design, its one of Harold (ultradyne) Berkshires designed for the larger mopar tappet.

      I put a 702 in a 69 318 with eddy heads, patriot headers (fits with power steering if you have it), air gap and a 650 AVS2....moves my large B with ease...and sounds good doing it.

      X2 on the timing chain set, and even manifold duals will be better than single pipe...you can always add headers as the budget allows. And unless your really comfortable with it..ditch the points distributor for pertronix drop in, or even a proform (MP)

      The 702 like 9:1 minimum...the 701 8.5 will work....

      Thats straight from the mouths of 3 different cam techs at Lunati.
