i strongly agree with both of you... :)

another thing that caught my attention, the airbox for these engines is really small in terms of air capacity.

What's your desired compression?

What's your desired compression?

Kit I have should give a 12:1 ratio with custom headgasket that was included.  Builder said he was checking compression ratio today.

hi, not said much lately  :o

So things changed abit. after the builder checked they compression ratio we found that it came to about 14.4:1 I think it was. So ive had to get the pistons machined. he machined some of the edges then machined all the piston down 0.5mm giving me a ratio of 11.8:1 with a cometic headgasket that he has had to order which is holding the build up now. The block is now completed and back together and the head is completed.









im not gonna' lie I cant get enough of pictures of the block! shame its all going to be hidden  :(

Hi

It is a pitty that it all gets hidden.
Did you get the crank balanced with flywheel and clutch?
To get 14.4:1 what connecting rods where you using?

Cheers

Yes its a pitty! It will be worth it i hope :P

Yes bottom end has been fully balanced

Standard length rods! Both head and block have been skimmed so maybe this has something to do with it?  I do not know. I never questioned it.

Good news today. The engine is now fully built.

So hopefully we will have an engine next week!

Looks like I'll have a busy weekend ahead of me!

final update before the engine comes. (ill be away all week when this engine arrives  :-[ )

ive baught a second hand mocal oil filter take off plate. the guy i bought it off had a supercharged m42 i belive. and he had to relocate the alternator to the exhaust side of the engine. but ive made a few guesses and I think I could make it owrk with original m44 alternator mount in place. and also using bango type fitting rather than straight or bend type fittings to the pipe. Also I purchased a plate to relocate the oil filter. The guy was a mocal dealer and suggested I wait for the new caps that screw in plate above the filter. but I wasnt kean on this idea as everytime I would need to change the filter I would have to remove all the pipework, as the m44 cap is screw on.


This also has a hole for a oil pressure warning light


here is a few pics of the crank sensor mount for the front off the m44 timing case





I will however beef the mount up as it has been suggested to me and possibly make a guard for it. as it is rather exposed.








And over the past few weeks ive rewired all the wiring that I have previously doe to try and tidy the interior and under the bonnet. I have also relocated the battery to the rear and fitted a master switch etc this pic is half way through, you can just about see the new switch panel and master switch panel

Hi

I'm surprised you don't go m42 head as getting springs and hydralic lifters for 10k can be attained fairly easily.

Just need to make sure the rest can handle it.

Cheers Rohan

Hi Rohan.

You are right I could have but at the time I wasnt sure if the m42 head would work. Thats why I havent gone "all out" with this head and gone for regrinds and a port job. Im going to see how happy I am with it. And in 2/3/4 years when this engine is going in the stage car with itbs and standalone I will then consider a m42 head, solid lifter, cams , and possibly valves.
