that will put the top of the block 16 inches above the top rails:eek: without any sump mods that is :confused: :confused: :confused:

wot clearence is needed betwean the sump and schassis?

16 inches or 16 cms ?
i haven,t got my car at home with me but i think the std bonnet sits 17 cms above the top rail at the bulkhead end if my my memory serves me correctly, my own engine is only the 1.8cvh, but it sits level with the bottom chassis rail & still fits below a std bonnet, in fact with approx 3 cm spare.

hmmmm head scratching time :confused:

Just going back to the chassis mod.

This is what I would do.

dogwood is on my wave length. that is the pic i shuld of drawn first. thank you.

andy. inches is right. i was looking at a 12 inch tall scuttle panel witch just clears the rocker cover to a custom nose cone work will make for me. the bonnet bump for the intake manifold to sit in will again be 12 inch tall. this setup i can see over. just. lifting the sump above the bottom rails will add 4 inch to this. though i can take 25mm or 1 inch of the bottom of the sump but that is still a 15 inch high bonnet and i am not that tall. ????????

wow, that is a tall engine :eek:

in that case i,d go with Dogwoods suggestion, just ensure you plate & fully weld the extra tube in place at the front area where it meets BR1, the engine mounts welded to BR8 & BR1 will help too.

good luck with fitting that engine :cool:

cheers
andy

ok. i will get on to that tomorrow..

thanks for your best wishes. i feel like i need it today lol

What about fitting a similar tube to the opposite side of the chassis so that the mechanical properties of the chassis are symmetric?

i dont know if i would like to cut the other side as it is not needed. i may then end up making the un cut side stiffer and the cut side the same as it was before.

i may be off the mark?

Keep us informed about the mods Leon as I am fitting the BMW M40 motor initially but fancy the idea if the twin cam once all IVA bother is done.

Leon,ask Spud about bonnet height. I could be wrong but I am fairly certain that the mounting flange on the bonnet that sits on the chassis rails on his car was cut off by about 25mm to fit the nosecone and scuttle as it fits to the chassis instead of the 25x25mm box section on page 99 fig 8.16 that sits on tr1/2 and tr8.
