Hi all, this is my first post. I have been reading a bunch and have learned a lot of new things. I am new to the inline world, with my '64 Chevy II wagon having a 250 six in it. It has a Clifford intake and header, Holley 390cfm carb but otherwise a fairly stock rebuild.
Recently I ran into a problem where is overheated enough to cause the #6 wrist pin to get tight (not seized) and cause the piston skirt to be gouged and slight in the bottom of the bore.
Since I have things apart, I am checking everything. One thing I noticed is how far down the pistons are in the bore when at TDC. I measured this at almost a 1/4" (.24x). I have been reading and really haven't found the answer.
On a 250, how far in the hole should the pistons be at TDC?
Thanks!!!!
