Jaydee Posted September 11, 2019 Posted September 11, 2019 2 minutes ago, 370steve said: can i do that on stock liners? or is it big block time? Should be okay with bandit 1200 pots. A bandit 12 with a 1246 bore should share the same wall thickness (in its liner) as an 1127 with a 1216 bore. 1 Quote

Then there is the possibility of breaking into the oil gallery in the cases - bores bigger than 81mm with corresponding bigger liners tend to use external oil lines and go dry block. 1 Quote

Diebythereaper Posted September 11, 2019 Posted September 11, 2019 1246 on standard B12 block - Building one myself - Best way to go IMO and saves cost and heat issues with big block 1 Quote

Diebythereaper Posted September 11, 2019 Posted September 11, 2019 JE make them as well - Dont know about a link, bought them from Sir Upperton a good few years ago, he looked after the boring of the block for me and ported the head as well 1 Quote

Lees 1340 never had a problem and a certain poster with a silly boosted one seams to get away with it 1 Quote
clivegto Posted September 12, 2019 Posted September 12, 2019 I have a 1340 big block motor with all the oil ways in tact in the crank cases where it's been opened out. 1 Quote
clivegto Posted September 12, 2019 Posted September 12, 2019 Think Warpspeed racing would make you a billet big block, the ones I have are sand cast. 1 Quote
