Ive made Nassis posts sticky.

Edit: Mert, it's not really too simplistic, but in my experience maybe I would elaborate to say that anything that doesn't serve an important service is OK. Things you don't need to touch, and maybe very simple components are OK.

However, my car is only just finished - it's done 700KM, and I have found failings in several of their products.

As noted, in my experience (using them for probably 20+ years) "most" are OK. Yes, some do not do well.

The "simplistic" was the comprehensive "they suck" comment. Both on "Drake" and "US builders" which as one-size-fits-all throwaway lines are, IMO, simplistic.

Others like that as its an easy answer... to each their own.

Drake makes over 10,000 parts, and unless someone's tried them all IMO its a stretch to dismiss all of them in one short line.

Keith Craft, Survival Motorsports, and dozens of other quality builders do exist in the US, and bagging the entire industry for one bad engine from some unnamed and out of business builder (again betting low price was the buying decider) seems a bit of a stretch.

One issue on Drake is the expectation of show car finish, if you look at a original Mustang '65-'68 you would be shocked at how badly the fit and finish was.

All I can say is the majority of the parts of their I have used work well, and are fit-for-purpose. Their 67-68 trunk letters suck, and have for over a decade (misplaced pins) and the convertible visor brackets I used did not fit well. A lot of the dash trims, clock and knob, and many, many other parts have worked for ~10 years with no problems.

I bought a brake pad form a local distributor, they gave me the wrong part. And a local Mustang parts shop is so jaded they can't even be bothered to assist in sourcing parts. On the shelf or go away. By the same logic above I could say "Australian Mustang parts vendors suck".

And the 68 S GT coupe I bought, local restoration begun and stopped, had 1/2" of bog over some of the worst welding I have seen. Had to remove and replace both rear 1/4s and the tail panel. So "all Australian restorations are crap"...

But I think neither are really fair comments...

I've taken the time to read this article with interest. I think the title is somewhat misleading.

It should read "Why you should think twice about buying an engine without knowing the engine builder."

I've seen a lot of local engine builders rort the customer, on not only old school V8's but Japanese performance motors. IMHO research as best you can before purchase.

In fact, lets make it "Why you should think twice about buying any Mustang part without researching the seller." - as I have half a dozen newish fuel sending units that leak at the wire and three door jamb switches that short in a nasty manner .


Yep agreed, I bought a Roush engine in the US nearly 50,000 Kim's ago, and it's been great, and a mate of mine who is well known on here, had three local builders screw him around and fleece him, it cuts both ways I'm afraid. Best to do your thorough research and save the tears.

It really is the luck of the draw. I bought the B&M AOD from rocket before I read all the warning on the Click Click Racing site to stay away from them and it's been great. 12000miles and going strong with a 1-2 change that will rattle your teeth when you get into it.

I've got a set of Keith Craft Brodix CNC heads waiting for my new short block to arrive. I'll report on how good the Dart engine assemblers are when I get it.

It could be worse it could be the other way around.

Ok more progress, probably should start a new thread but the new 4" stroke 4340 internal balance forged crank and 6.2" H beam rods have showed up for the 408 build, can't wait. About order more parts, this weekend, going with a Lunati Voodoo roller cam rather then comp cams, this cam ahs much more lift then the last one. Rod has an 850 Demon carb, have a virgin roller cam 351 block ready to go. Should have no issue pulling the Olympic caravan Poke

Yeah the lunati roller we put in dads car had a lot more lift than it's comp counterpart - 0.612" I think it was. Very interested to see how it goes, but apparently it sounds great.

yep thats the one I'm looking at, but also considering the next one down from that ( part no 20350711 ), haven't decided yet as I don't want to loose any of the low down torque..which I may with the larger cam.

Do not forget that SP is building a 408 for this client. So it will make the Cam milder than if used in a 302. Remember the 408 is 33% larger engine. So your 351's case, going for the next size down would be similar in behaviour.


I will someday think of something clever to say.

Oh yeah, I should have mentioned that my old mans is a Clevo... they must run higher lift, coz his cam is not all that big. 2000-5500 range

Clevo has the 1.72 ratio rockers by default rather than the more common Windsor 1.6 .
