bludestiny Posted November 11, 2016 Author Report Share Posted November 11, 2016 So my plans of a stroker have been dashed, mostly because I came up on a good deal for a set of rods and a new crank from Mr. Ermish. The machien shop I am going through said for the price that Troy gave me vs having him fix it up, I should just go with Troy's stuff. I do want to still overbore the block. I know the Z dished pistons are a fit in terms of pin height and dish. I am going to be going with some ITM +1mm overbore pistons. That would be a 2mm overbore which should be safe. This will also be a pretty cost effective build. 1 Quote Link to comment
bludestiny Posted November 12, 2016 Author Report Share Posted November 12, 2016 So this sage just gets more curious. I went out today to actually confirm I had a u67 head, but turns out I have a closed chamber A87. Plan right now is still to try and find some +1mm L28 dished pistons and bore the block out. According to Ozdat the comp ratio will be 9.4:1 If I use a 41cc chamber size which I read off of the dime quarterly. I took some picture of the head, chamber, valves etc. Valve sizes Intake/Exhaust Quote Link to comment
Stoffregen Motorsports Posted November 12, 2016 Report Share Posted November 12, 2016 It's probably got soft valve seats in it. Unless you know otherwise, be prepared to have hard seats installed. 1 Quote Link to comment
