skimming a m44 bock i have am m44 that i am going to build for my rally car, i wanted a m47 crank for it but them seem to be hard to get. so option 2 is just to skim the block and get the compression up, but i was told by a guy who builds engines taht it would create headaches due to teh ciming chain covers... is that true? i want about 11.5:1 i also have s52 3000cc pistons for it. Is there any other pistons i could use that are taller? I have heard of vauxhall ones, but i havnt a clue which. Also, reving to 7,000 do you need arp bolts? is there any other tuning tips you could give me please? thanks Last edited by bmw2101; 02-08-2014 at 07:46 PM. |
