Let me put one more thing out there, especially regarding rods:
If you don't buy the American product, there is no incentive for American company's to make make one and if you don't request additional products, there will never be any options made, to any base product that might still be made in the good old USA.
Think about it.
Quoteon other forums will be quick to talk about how great certain South Korean products are.
Ross, you will tell people to hit the road because they want to use the Pro Maxx head that cost $1000 less than the TFS and say you "have" to use the Molnar rod because it cost $400 more than a American one?
I don't think many people realize the Molnar rod is made in China, in part, at least, because both of you use them and promote them but, say you won't use Chinese stuff.
BTW, besides Crower still making rods, Carillo and Oliver still make rods. What company hasn't copied the H beam Carrilo rods?
If you want to keep American rod manufactures in business, those are the rods that should be in quality builds.
and all the reasons it told me so. It even sent me for more pictures to prove it.
QuoteSorry for being parochial, but I still can't support a Chinese casting regardless of it being finished at home just to save a buck. I know it's a sign of the times, but 25.5 years in the military and seeing that emboldened theft in so many ways, they won't come through my shop, even if I lost a sale (or multiple).
I assume that also goes for Molnar rods?

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.
I'll be straight with you, dude.
The SpeedMaster/ProComp/et al is junk. And yes, it's cheap Chinese junk, just like the lifters you bought.
I don't use their stuff, but have seen plenty of it fail: heads can't pass a pressure test, seats need valve job, guides fall out, roller rocker arms spit out needle bearings, distributors fail.
It's cheap for a reason. You play the game, roll the dice, and see if it works for you.
