crossflow
Hi guys,
I'm looking at buying a 1600 crossflow for my Haynes Roadster and I'm aware of the different blocks - 618 and 711M. Because I'm on
a bit of a budget how much worse is the 618 block than the 711M as there seems to be a significant price difference. Also, are the different blocks
interchangeable? so if i got a 618 block engine can i change it at a later date for a 711m block? or should i just man up and buy the 711m block
now?!
any help on the blocks and what you can do would be much appreciated!
Ben

Thinking along the same lines myself. I ran one on the road with no probs when I was a youngster, I’ve got no intention of racing it , just want a bit
more than the1300. I know in my old Mk2 cortina I rebuilt the engine with a flat head, BIP pistons a cam of some sort, twin choke weber & a four
branch bunch of narners and it went hell for its day. Maybe what I’m doing now is trying to relive my youth. (Sad sod). But of all my cars that was my
favourite. But if you were going to drive with your foot on the floor all the time I think I would go with the stronger 711

Well I'm not going to seriously race it but thought i might try some hill climbs and sprints and inevitably in this kind of car i'm going
to want to put my foot down so thanks for the advice and I'll hold off for the better block.
What kind of rev range can you expect from a fairly standard 1600. i hear they don't rev amazingly well?

I cant remember how well it reved but it wasn’t standard for very long and I know it didn’t rev as freely as my present 1300

711M block (AFAIK) is the one to go for. I had one years ago and with relatively simple mod and work they can be made to rev reliably to 8000rpm. In
fact back in the early 80's I found the weakest link was the early single rail gearbox (mk3 cortina) which was around 20k miles to a full
rebuild. Where as I liked rebuilding the Xflow at 40k.
spec was 1662cc, 11.0:1 compression, full race head (flat face), power max twin-cam pistons, lightened, ballanced, twin 40's, fast road/race
cam, piper ladder rocker box, ....... cost me nearly £1600 back in 1980.
In my mk1 Cortina it would pull 8000rpm in top with a 3.77 diff. (top end of nearly 140 if you work it out)
Cruising at 70mph it would give me nearly 30mpg as well.
Beware of the Goldfish in the tulip mines. The ONLY defence against them is smoking peanut butter sandwiches.

Not a crossflow, but surely a better option:
*BRAND NEW* Ford Zetec Engines 1.8L Black Top - 3 Available | eBay
Similar things must come along every now and then.

Yeah i did think about a zetec but i would like a crossflow for classic appeal and also they're mechanically easier than a zetec where i would
really just buy an ecu and get someone else to programme it which i wasn't keen on. also, i can only see crossflow prices going up so i'm
calling it an investment in the future

1300 block + lotus twin cam pistons + 234 cam + lightened & balanced everything = awesome budget 'screamer' crossflow

I have a 1700cc Crossflow that I need to sell, but I won't be back home until some time around December. It's got a couple of bits removed
for my new engine but otherwise it's got nearly everything needed to run. It was tested at 110bhp last year.

Sounds brilliant how much were you wanting for that?

There are 711 engines about . I gave a load of parts away a few months ago, enough to build a complete engine apart from a sump.

If you want an even better crossflow block i have a thick walled ax block just needs a rebore but you can go past
1700cc with the ax block. Also got loads of other bits. 2 heads, crank, +90 pistons, 234cam that was ran for about 40 mins.

Also, does anyone know if any parts from the 618 block and then 711 block are interchangeable?
