okay i have the orders " get rid of all those car parts"... but i havent been told how so heres the idea,
* a12 block bored out to accept a15 pistons (76mm bore to 79mm bore as per specs on datsun1200.com) and fitted onto a12 rods (what nees modifying again?)
* this all to be topped off with an a15 shaved head to inc compression and line up with a12 bores with a webber 32/36 (that ive almost finished.

the reasons for this are that i cant be bothered with the engineers or other methods of a15 block insertion linto the 1200 so next best thing.

will the a12 block have enough meat to be bored out that much and will the a15 pistons be okay on the a12 rods? and why has my a15 fuelpump got two lines running from the pump to the carb? never seen that one before.

Ideas and comments would be appreciated.
