What valve springs are they?
Most roller lifter problems I've seen are caused by not enough spring pressure or too much.
If they are procrap springs that's likely the problem.

well had car booked in to be tuned thursday (yesterday) to find out that a couple of the brand name comp cams lifters are not bleeding up properly so they could not tune the car. just to prove that even good brands can have some issues. by the way i am using T.I performance j3 chip for the tune.


Are you saying you couldn't hear the rattle of a collapsed lifter or two? If they were not pumping up, it would run like a dog, and rattle / tap quite a lot.
Are they windsor or cleveland Comp lifters? The hydraulic rollers are different.
Who machined / balanced / assembled / ran-in this engine? That can make a lot of difference to the final result.


Hi there
Im 347 ef's brother, it was popping a bit on idle but when the revs come up it was smooth but with all the computer problems it has just thought it might be the computer as it wouldnt rev more than 2500 and it was only faintonce the engine stops it bleeds down straight away,as for the procomp stuff the heads look as good as any other real smooth ports and valves lined up perfectly piston and rods were also smooth with no rough edges anywhere and it is a late model 5 ltr block so they are roller lifters apart from that it runs real smooth. sounds good and when it finaly gets tuned we will post the results but for now it is still running stock thottle body injectors and fuel system so it wont be at its full potential yet

Mate wish you all the best with this one - at least someone is having a go instead of relying on second-hand boo-hoo procomp ate my mum boo-hoo stories, they have been around a while now so maybe they are getting their sh*t together! good luck and keep us posted. :D

To bad the stuff is made out of plasticine. Smooths mean crap all. I'd rather see it built stock rods over procomp rods anyday.

As far as the cranks go. I've seen plenty of them be deemed impossible to balance to an acceptable level. You might get lucky, but i doubt it.

Oh yeah and don't crap on about a couple of faulty compcams lifters as if it some how justifies the use of procomp.

The whole procomp build-quality issue is well documented, and has been thrashed to death in many forums worldwide.

But the reason why I personally wouldn't touch the stuff is simple. Procomp PIRATE copy various other manufacturers goods. So they don't invest their own money in R&D, they buy a single item, cut it up and try to copy it. By supporting procomp (buying their products) people are not purchasing the "real deal". So the pioneering manufacturers who do this all important R&D have less to spend, and so our range of options decreases as they concentrate on the bigger & faster moving lines, and prices tend to rise as the economics of scale/quantity are reduced. So the "cheaper" prices that PIRATE goods carry tend to become the over-riding decision making tool for uninitiated purchasers. And so the downwards spiral continues.

Before long there will only be a few true manufacturers left who undertake R&D, and then who looses? We all do. And the procomps of this world just move on to the next easy item to copy, probably in a completely different product field.

I do not knowingly use any procomp parts (or other Pirated parts) an any engines that I build. If enough of us vote with our wallets procomp will move along sooner rather than later.

I hear the "Pirating" touted about a bit here and honestly - doesn't every engine rebuilder who modifys a piece of a motor to make it better(possibly)than the bit was in the first place? If this is the case we may as well poo poo the whole performance industry as they buy a "R and D-ed" cam/crank/rod/whatever and modiy it - it goes around and around! I modify my mini parts(Cranks and blocks modified wayyyyy beyond what they were ever designed to do) as well as my Ford bits and if that makes me a pirate - so be it! I am happy with it and I reckon EF will be too with his pro comp stuff

As for pro comp - got it installed in Mum's XD ute - 302W with the Pro Comp kit through it, 270,000km and not an issue with mum driving it like it is stolen(hot rodders/truck drivers wife no less). Who cares if they modify someone elses stuff...as long as they don't do anything illegal and there aren't serious failures it shouldn't matter in the least. I reckon leave the guy alone and let him do what he wants to do(as did I with Mum's car!) and get on with it. Sure it may not peel the skin off a warm custard(figuratively speaking)but it is his car and his wallet - lay off him, stop bagging him for his choice in product and roll on with what the discussion is about - modifying our Fords.

Help, not hinder!

You seem to misunderstand the term pirating

A pirate makes identical copies of someone else's work, porns them off as their own, and collects the profits without spending any of the R&D development costs. Procomp copy products made by Edelbrock, Dart, MSD, Holley, Ford, Mallory, Crane Cams, Chevrolet & probably a whole lot more. There is no "modification" or development involved.

Modifying a piece to improve it's original design is exactly what hot rodding is built on, and precisely what the aftermarket does. This is the R&D that is being jeopardised by the likes of procomp stealing their intellectual property, and people supporting this behaviour by purchasing their parts.

3 out of 4 procomp pieces are probably fit for purpose (street use). But the failure rate is unacceptably high. Following the chinese business model, it will be replaced (and this is built into the selling price), but the collateral damage generally won't. A really good example is their distributor shafts breaking below the gear (not the roll pin). This stops the oil pump spinning but the distributor continues to drive, as does the engine. The engine runs without lubrication and massive internal damage is caused. The $99 distributor is replaced under warranty, but the owner is left to repair the collateral damage.

Personally I don't care who buy's what for whatever reason. It's all personal choice. When money is tight a cheap part can seem like a bargain. All I did was to state my position and the reasons for it. I enjoy my hot-rodding and want my kids to be able to do the same, and by purchasing name-brand parts from reputable manufacturers it helps ensure they are in business tommorow developing new performance parts.
