pinto cam - burton BLF 40.41
in a moment of intoxicated ebay action i have managed to win one of these on ebay.
From what i can tell this may be quite a lairy cam? cant seem to find much info on it though.
Its cam only, what else am i gonna need to put it in? new followers etc? springs? vernier i presume.
engine is an injection 2.0 head and twin 40's.

Burton are pretty good with technical advice and will happily advise on what's needed. As a minimum I'd fit new followers and retainer
springs, oil spray bar, front oil seal, valve stem seals. Valve springs may be OK, but again Burton will advise whether stronger or double springs
are recomended for th particular cam profile.
ETA - best to replace the cam bearings while you have it apart and yes, a vernier wheel will allow you to get the best from the cam - my engine tuner
(Tom Airey) maintains that even the standard Ford cam benefits markedly from accurate vernier timing.
Hmmm! - not much detail on the Burton website...

I'd at least go for stronger springs as the standard ones are quite weak, you'll just have to make sure you have a rev limiter fitted.
Might end up a pain in traffic with little torque.

Thanks guys, I think I'll contact burton and see what they recommend with it.
Verniers arent cheap are they!? just had a look at them. Im sure my CVH one was never that expensive.

It would be wise to consider the bottom end of the engine as well, this is a pretty hot cam so power band likely to extend further than the rest of
the engine would like to go.

Yes I had wondered about that - perhaps some ARP's are in order (and so the cost spirals.....). Or else a limiter as whippy said.

To be honest limiting the RPM is going to make a bad tempered engine with lumpy idle and bugger all low end power, but without the full power benefits
at high RPM which this cam is capable of.
If you are sticking with the stock con rods and pistons, then IMO your best bet is to sell this cam and buy a fast road cam.

are the standard rods n pistons not up to the job then? After this post:
http://www.locostbuilders.co.uk./viewthread.php?tid=98896&page=2
I kinda assumed that I could dial the cam in to make peak power somewhere a little over 7k and not need to worry too much.
iirc correctly aftermarket cams usually have a range between which you can tweak the power band - eg 116-120degs for my CVH turbo piper 285T.
the pinto is only a temporary measure (just saw this cam and thought it might liven it up a bit, like i said, impulse aided by beer) until we go
duratec. having said that i dont want it popping after 5 mins.
