thanks dodgeman i intended to replace all the bolts anyway. as i stated in my original post suppliers i have talked to havent been that helpful, perhaps im not asking the right questions. does any body in brisbane know of a reputable supplier who may help?

hey guys hit a snag in my l 18 rebuild and was hopping someone may help. i broke a bolt on the rear main bearing when i torqued it down to measure the journal. all of the suppliers i have asked tell me that they are unable to get l 18 main or head bolts and can't tell me if the l 16 or l20 bolts are the same. has anybody else had this problem or can someone tell me if these parts are interchangable. from memory the main bolt thread patern is m10 X 1.75 x 75 long.

edit:- may be 70mm long

i run a tf gemini radiator in my ute (same hose size) got it for $200 new about $80 cheaper than a recore. can see the gauge move as the thermostate opens and closes. unfamiliar with these condom filters though that may explain the kids

74 1200 ute a15
72 1200 coupe (awaiting rustoration)
79 pa10 stanza (l16 soon to be l18)

wow what an epic read. keen to see the end result. your dedication and craftsmanship are a real credit to you. hopefully you will have it done in time for the dat nats meeting shouldnt be hard to find a buyer there.

take the struts down to your local engineering shop they will spin a couple up for you. It could cost a bit to have some made, alternatively they should be able to tell you the thread form so you can hassle any industrial bolt suplier.

I have one in Brisbane on the south side

thnks for posting that pic saved me the trouble. If this is the norm how should i go about flowing them up a bit? i am not building anything extreme i was just going to smoothe out the bends a bit. I have lightened the flywheel and knife edged the crank in the hope of a few more rpm. i will probably get the standard cam reground, and have a pair of su's and flat top pistons. can any body tell me if there is any need to even out the exhaust ports.
