so..... either i just got the bargain of the week orrrr i'll get a message saying it was a mistake on the price and i've been refunded.

 i had a chinese edelbrock 500 carb in my ebay watchlist at £163 waiting 'til i have the money spare to buy a pair for my tunnel rammed fe ford. today when looking at myebay the price was £17.98!! so i bought a pair... of course. then trying my luck i typed 600cfm carburetor, clicked cheapest first and they were listed at £22.98!! so i bought a pair of those too for our ashley's '63 ford zephyr gasser. we're building a tunnel rammed 440 mopar motor for it

now it's a waiting game to see if they all arrive.

as far as packaging it was the same as other cams i've bought, whether they be 'brand' names or generic melling ones.  i'm not at the springs/retainers stage yet, it depends on whether i get aluminum heads or rebuild the iron ones for now. it's all budget dependant really. if the used 360 runs ok it'll go in the nash while i collect parts for and build the 390. you never know, if the budget will stretch and the 360 is ok i may get a stroker kit too.

thanks again for your help guys, unless s/hand edelbrock's turn up it seems 'for me' promaxx heads will do the job. i will spec the smaller valves too.

If you’re going to buy new heads, buy Trick Flow.  Get your moneys worth.

agreed, but they seem to be approx' $1000 more (50%) than the promaxx heads. i'm not building a track car, it's just a fun driver so although the best would be great if i can't afford the best..... i often say to people it doesn't matter how much of a bargain something is, if you don't have the money it's still unfortunately too expensive.

Promaxx heads are pretty decent, they put quality valves in them and the machine work is nice or it least a set of SBC that we installed for a customer were,, our local machine shop was impressed with the off shore pieces and said everything checked out good (BTW they hate Speedmaster).

i never knew promaxx did fe heads. i just had a look on their website and the maxx 170 head set up for hyd' roller cam would be most suited for my 390 build. cheaper than edelbrock rpm heads and with bigger valves and smaller chambers. thanks for the tip.
so has anyone got any experience with the promaxx fe heads?
thanks, neil.

less than 3 days from ordering it my clutch kit arrived from rock auto! boy they're fast (bear in mind i'm in the uk).
neil.

thanks for the advice everyone 
i'll pass on them then.
neil.

before i start please don't let this dissolve into another china bashing thread. i'm in the uk so any heads i buy will be 'overseas' so....
 has anyone used speedmaster aluminum heads and/or their aluminum roller rockers? i've got my roller cam and lifters now so i'm thinking why not get better heads and rockers now. it'll mean the 'to order' pushrods won't have to reordered if i do the change later so..... makes sense to me anyway. the plan has always been to fit aluminum heads later so why not do it once.

Not clear about foundry costs, but I think this printer is around $40K upfront, but can obviously be used over and over...

That prints in PLA and PEEK which are plastics.

Not suitable for things like intake manifolds and such...

i guess that depends on the plastic used, most modern intake's are some kind of plastic these days. any threads needed are taken care of by pressed/screwed in inserts
