Look what I have got, what is it?
OK, before you start, I know its a pinto, but what variant, it has a 205 block.

... i think this is an injection head due to the pearshaped inlets, but it came with a carb inlet manifold

Looks like an F2 stock car exhaust fitted?
Yes that is a vernier pulley  albeit of a rarer sort.

... so why has it got a fuel pump?

It might have had the pump fitted retrospectively, - if it has been running on 45's for instance
Probably got a hot cam in there if someone has taken the trouble to fit the vernier pulley

Also where's the dizzy gone?
Has it been running with electronic ignition?

if we are going be anal about it, its not a vernier pulley  but one which can be changed in increments of 22.5 deg, no??

I got it from a fellow locostbuilder (who also has some really juicy bits for sale - he will post himself in a bit). He has removed the dizz and
fitted the cap, as he was going to run megajolt.

..I measured the cam, it has a core of 30.4mm and a lobe diameter of 36.4mm - it doesn't seem that high, it is worn badly but I measured on the
outer edge where there is no wear. I also got a replacement cam - can anyone identify? The spray bar and followers are all new, but the cam is used
but has no wear at all

Er no actually, It's hard to describe, but there are two wheels, an inner and an outer, they have unequally spaced holes and if you move the
outer to get the marks lined up, one pair of holes will line up and all the rest wont. If you need to move the outer fractionally, then you move it
and put the peg in the next match ing pair etc.
Sorry if the above is tricky to understand but the pulley does give very fine adjustment.

Are there no numbers or letters stamped into the end of the cam?

Well if it is from an F2 stockcar it could be any cam. many of the engine builders have their "own" reworked profiles. It'll also be
VERY peaky with a short power band. Pump could have been left in just to seal the port off or IIRC something to do with the dizzy drive and it being
connected in some way. Strange that the dizzy is missing though.
Also is the water port at the rear of the block (exhaust side IIRC) blanked off as well ( another F2 kwirk sometimes).
If it is an F2 from one of the bigger engine builders it'll be quite high in compression AND you'll need to look out for the spark plug
electrode being in the right place to avoid the piston closing the gap re another thread on here yesterday.
OR it could just be a pinto and I've wasted half my night typing this lot LOL
If it looks wrong it probably is wrong.

My last heavily reworked Pinto had high compression and I had to resort to 24V starting. If you've got a Pinto what does the weight of another
battery matter

I think with a valve lift of 6mm we are not talking anything too dramatic

There should be a plate that bolts on the front of that pulley to hold the peg in place, if missing easy enough to spin one up in a lathe. I had one
of those years ago, got it from Burtons I think and thought it was really good, much better than three grub screws! the adjustment is very fine,
fractions of a degree.

nope. unless someone corrects me, pinto had finger followers so lobes do not directly push the valves.
there followers will have some lever effect so the valve list fill be more than that, I would guess in region of 15 mm.

Can anyone measure a standard cam so I can get some comparison?

Yep, the one on the Pinto is a proper vernier adjustable pulley, as opposed to the ones that simply clamp two parts of the pulley together and use a
vernier scale to measure the relative positions.

I should check that there is a shortened Dizzy shaft under that plug, as something needs to drive the oilpump...

The AE replacement is a standard spec cam. Cam lift of 6mm equates to a valve lift of about 10mm with std rockers.
