Block numbers for Kent engines

flockofseagulls · 24 May 2006, 18:18 (Ref:1618111)

Hello all.

Im new to this website so apologies if this information is already in here. I have recently bought a Jamun M89 (Nathan Frekes old one) and im after a spare engine for it. I have seen a number of crossflow engines but I would just like a bit of background info. I have been told the block number should be 711M 6015 BA, but there are 1600 xflows out there with 771M 6051 BA codes? I am told that the 711M was for RWD and 771M was for FWD. Will they both fit in a FF1600? Any input appreciated. By the way I am a complete amateur so go easy on the technical terms please. I live in the north west so will be looking to get 1 maybe 2 engines race tuned.

Many thanks.

I'm not sure what the block numbers are, but I'm sure Bernard Baxter will be able to offer some advice. He takes care of my engines, and is North West based.

I dont have his contact details, but will get Kartingdad who posts on here to send them your way.

711M is the block number you need. This is specified in the tech regs for FF1600 produced by Ford, but Ford don't want to know about FF1600, however perhaps we had better not go there! There are also casting numbers on the block, in the middle towards the top, usually beginning with a T. General rule is the higher number the newer the block, T16 being one of the higher numbers. Other people on this forum will be able to provide the tech regs you need, I have lost mine!! By the way, welcome to ten tenths and FF1600!

Thanks for your help on this guys. I've bought a 711M from Peterborough so that should be on it's way in the next few days. Unfortunately I've also bought a couple of 771's oops. Anyway that just goes to show my inexperience! Very helpful advice. Thanks for the welcome Verglas.

There are mainly 2 types of block. The 711m block was manufactured in the uk a million years ago.
More recently,just after the last ice age, Ford manufactured the identical block in S. Africa. This block, as far as I understand it, is made of a more brittle type of cast iron, which makes it more prone to cracking.

I think that there is a 3rd block which has been made in the last few years by Ford to keep ff1600 going. I don't really know how good they are.

Anyway, what you want ideally is one of the original 711m blocks which were fitted to escort mexico's, cortina gt's etc. Apparently, the cast iron in them 'weathers' and relaxes, taking any stress points out of the block. They can still be found lurking in breakers yards etc. and are, I think your best bet.

Bore wear isn't a problem as unless you find one that has about 1000 miles on the clock it will need linering anyway.

As Jnr Jnr said, in my opinion, talk to Bernard Baxter at BB Engineering for a more informed and down to earth chat. He will put you straight without any glammed up hype.

His moby no. is 07759 888930, but I suggest you don't call him until wednesday as he is running a couple of historic ff1600's at Pau in S. France.

Neil Bold Engineering prepare a lot of engines for people in the North West Championship and are based near Manchester. Give Neil a ring on 01204 571636.

The T number on the side of the block is quite important. The higher the number the better. Anything over 15 is good.

Mine is a T18 if I remember correctly

Many thanks.[/QUOTE The 2 blocks are different & they are not interchangeable, 711M 6015 BA is the FF1600 VERSION ONLY.

What about the AX blocks?

"711M is the block number you need. This is specified in the tech regs for FF1600 produced by Ford"

Not sure I agree with this - can't find it in the regs.

Thankyou everyone for your help. All this information has cleared up a lot of confusion from my side.

Cheers
