Quote: Did anyone order their block with the oversize sleeves. 4.7 vs 4.62? Any drawback to going oversized to get the .100 thick at 4.5? At 4.7 OD on the sleeve that only leaves .050 aluminum between the sleeves. Would that lead to cracking problems?
I'm getting ready to order a block. Ay input would be appreciated.
Thanks
Oops, looks like I replied before but...
My low deck block has the 4.700 sleeves with o-ring grooves. It is currently bored out at 4.538 and still going strong, but this build up is probably the last time before it needs, er I mean gets new sleeves. It has lead a hard life on spray and with me lots of RPM.
