Send a PM to Fastcarl on here - he supplied my bolts and washers.

Looks very sweet Ben! Funnily enough i'm building an almost identical engine for my 1970 Morris at the moment. Only main diffrence is mines running an Eaton M24 Supercharger Aiming for a a low boost 100bhp.

Have you thought about running a cross pin diff? For the money it's really worth it compaired to just fitting the uprated pin.

Hey! Is this Matt?
hmm supercharged small bore.. sounds good! would like to see that.

Actually I have just ordered the minispares crosspin diff.. must update that. But yes I agree much better than just an uprated pin. I know its not going to be pushing the limits of A series but definately pushing the limits of small bore

How your website coming along?

Yeah it's Matt, well yeah i thought it would be a little different and with the small Eaton it should suit it well. I'm staying away from straight cuts though as it's a daily driver, i'll leave the noise for the GTM

Ah good choice with the diff! they also have a small effect on reducing torque steer which is nice! Your going to run tens arn't you?

We seem to have the slowest and most usless website designers in Devon! but yes should be done in the next week or so, thank good!

Different is good I must come down over the next few months and come you all... would love to see this engine. I love the straight cut noise so its got to be done the plan is for it to be a daily driver, but its slowly steering away from that lol

Yup im going to be running spectrums they are stashed away safe for the moment though!

Oh awesome, well I hope its up soon.. thats taken ages!

Right... A bit of a problem!

I was just checking the measurement between the top of the pistons and the deck of the block to let Swiftune know, so they can work out a CR, now... here comes the problem...

I had all the pistons decked by 18thou so they would be close to the top of the bore on TDC as the block had been skimmed by the previous owner.. now the pistons are in and on cylinders 1, 2, and 4 the the piston sits at an angle to the top of the block by 6 - 8thou either side.. so sitting 8thou down on the left side (flywheel) to 2thou down on the right side (rad)..

Now I know the pistons have all been decked flat, so do I have 3 BENT RODS?!!?!?!

Also, on those 3 cylinders the piston doesnt sit in directly in the center of the bore.. I cant get a 10thou gauge all the way around the piston but can on cylinder 3.

Help!

[benpopham]

Update...

4 rods back at Saunders, to be straightened.. 1 step forward, 2 steps back!!

Also received my new modified head gasket from MRA minis, nice work Martin!

[AndrewJ530]

Could you see the bend in them once you'd took them out ben or was it too slight to make out?

[BJst416]

lack of knowledge on the matter really: I've been told with +080 you need to offset the bores?

[benpopham]

Hey
they were all between 4 and 6thou out which is only a very slight amount and impossible to see by eye, but enough to ruin my engine!! glad I found it really

[jayare]

That's a pain in the rear - best to get it sorted now though and good job you spotted it,

[GreaseMonkey]

That sucks sorry to hear about it, hope you get it sorted quick

Really good that you spotted the problem now rather than later on

[benpopham]

OK.. now Im really cofused, The rods have all come back from Saunders and they are all straight so now Im thinking that maybe when the crank journals where re-ground to +10thou whether they were done badly?

Because if the journal was 1thou out, by the time it got to the top of the piston it could be as much as 8thou wrong?

Very confused! Oh well.. going to reassemble it tomorrow and take another look.

[benpopham]

Right... block to piston height fixed going to pick up the engine again on Monday and the build can carry on!! wooo!!

Spoke to Swiftune today and the rest of the bits for the engine are looking good too

[Tim1970]

Glad to hear it's all sorted now.
What did it turn out to be in the end?
Look forward to seeing the bits from swiftune.
