rite the my mini has a 998 a serise in it which need a cylinder resleveing and skiming but have been offered a 998A+ bottom end crank, block, pistons so what im thinking is can i use the a serise crank(already been reground) in the A+ block, pistons and rods other than that and the distributor are there any other complatible problems .

thanks alot rob

Yes - that should be fine. Take the chance to fit a better cam while you are in there!

[Cooperman]

Use the original primary gear as the A+ transfer gears are different.
As 'bmcecosse' says, a better cam such as the MG Metro or Kent 266 would be a good thing to do whilst it's in pieces.

dont bother with the webber just keep the su or upgrade to the hiff38 with the head you have i wouldn't go hiff44 but others do and works ok but i have found you lose a little bottom end power. you wont need straight cut drops for that spec but assume your going for the noise. 998cc straight cut drops are not cheap

[bmcecosse]

I agree! Dump the ghastly Weber - and straight cut drop gears are a waste of money except for full blown race/rally engine. As many on here will know - I prefer the 940 head - but try the 295 since you have it! It will be fine.

hiff38 you wont need straight cut drops for that spec but assume your going for the noise. 998cc straight cut drops are not cheap

already have a hif which works REALLY well but the webber was just a stand out from the crowd abit and the striaght cut drops i love the noise and if there going to cut down on transmision losses even better

thanks everyone robert

Be sure to put a centre oil pick-up in the box!

Be sure to put a centre oil pick-up in the box!

way ahead of you there did it last winter when i rebuild the engine and box

[bmcecosse]

Excellent!

[valve bounce]

thought id add 3.4 diff and 10 inch wheels will be used,
does anybody have any other sugestions on the spec

[bmcecosse]

!0" wheels are what the car was designed with! Go for it. Final drive ratio is your choice - but for climbing up Shap.........

[In-a-mini]

straight cuts dont really save any power losses unless they are the roller bearing ones which help a bit. they are just stronger and dont side load the cases. i know what ya mean about the noise tiss good.
