CVH Engine height?
Due to what appears to be a severe shortage of 1600 crossflows for sale in the Sout West, I'm looking at alternatives for my newly acquired
Striker. It has quite a low bonnet (without the power bulge of the newer strikers) so height is fairly critical.
I found what looked to be a very useful engine comparision at http://www.westfield-world.com/Enginespecs2.html which suggests that the CVH is just
10mm taller than the crossflow. I am a bit dubious about this, and some of the other numbers in there seem a bit unlikely to me as well (is a
K-Series really only 10kg lighter than an xflow?).
So getting to the point, does anyone know how tall a CVH is in relation to an xflow? If it will fit I can probably get a 1.8 Sierra unit for very
cheap/free, do these have engine mounting points in the middle of the block? (unlike the FWD 1.6's). I know they are fairly crappy engines, but
I just need some cheapsish and readily available motive power for now.

Hi
I have a 1.8 CVH and it measures roughly 60cm from bottom of shortened sump to highest point on rocker cover.
The 1.8 block has engine mounting points in a similar position to a Pinto - i.e. in the middle.
Cheers

CVH definately fits a striker, and Jeremy Phillips likes them. He's still got some of his old striker pages on his current site.
Handily he has a picture of one fitted and his opinions here:

Comparing engine weights seems full of problems. There isn't a standard as to what should be included so direct comparison is useless unless
the same person does the measurement (should it include oil, altenator, exhast manifold, carb/injection etc etc etc)

Would go for a 1.6 over the 1.8. I ported and polished a 1.8 head recently for a mate and although it's now better what they say about the
design being for economy is an under-statement.
A Zetec is also worth a look.

Yup, CVH isn't a bad engine, actually just as tuneable as a crossflow. As standard, they have bigger valves, so the heads flow far better than
even a well modified crossflow. I've seen a really neat XR3i engine in a Locost at Donington last year, which was fitted under a standard
'book' bonnet.

Thanks once again chaps, this place really is invaluable.
I basicaly want to get this on the road ASAP, and as everything is ready for an xflow to drop in (including a pair of already jetted 40DCOE's),
I will hold out for a little while to see if one turns up, but I need a backup plan, preferably one that dosn't involve chopping holes in the
bonnet.
If it fits a 1.8 Zetec would be great, but it appears to be quite a tall engine, and has an alloy sump which involves more expense to get shortened,
on top of DCOE inlet and exhaust manifolds. If there is little height difference between the CVH and the Zetec I would definately go for the
Zetec.
I have a 20XE that was destined for the Locost that I would be happy to use, but even with it's Westfield shallow sump it's a big lump and
I'm almost certain it wouldn't fit without bonnet mods (though I still need to measure up and confirm this). My locost frame is 1"
taller than standard with a fairly tall bonnet so the 20XE fits with reasonable ground clearance.

The general concensus seems to be that the 1.8 head is a non starter for tuning. However I think it is possible to fit the 1.6 head to a 1.8
block.
My understanding is that the pistons need to be changed to keep the compression ratio up - 1.6 has same bore as 1.8 so I suspect these can be used.
I would have thought the above combination with ported 1.6 head and some decent carbs should make a good cheap engine.
I could be totally wrong though - once I'ce SVAd my car I'm going to have a go at building one so I'll find out one way or the
other.

Aren't Xflows fitted to older Fiestas?
I was in my scrappy yesterday and they must have had 10 of. I'm going back at the weekend if you want me to look for you.

I've been told that the FWD xflow block and crank are different. The block also dosen't have the RWD engine mountings cast in to one
side.  Thanks for the offer though.
