I had a few minutes to tinker today. I have several concerns. First I’m not sure I trust my “budget precision measuring” tools. Lol. I know better. I’ve double checked everything I’ve done so far and this is just a mock up anyway. Buuuuutttt, I can’t stand the thought of trusting all this work to plasti-gauge. Although I measured with that also. Plasti-gauge says .0015 on all mains. Great. Bore gauge was less. Like half that. Could be user error. I’m certainly not finalizing anything without some expert confirmation. Luckily my neighbor has nicer tools and has offered to double check my work for me. Honestly this is the first engine I’ve put together and scrutinized every measurement. Too much money involved here to just slap the kit in and “let it eat”.
Next, I’m only going by the FSM for the .0015” main clearance. There’s no documentation with the stroker kit saying what they want for mains clearance. Is that in fact what I want? I don’t want to assume anything, but you’d think the kit would be packaged to work together properly.
Ringed a single piston using a .016” end gap from an equation for N/A street application. Found TDC with a dial gauge and measured deck clearance using a straight edge and feeler gauge. Came up with .011” deck clearance. The pistons are -11cc, of course a 3.250 stroke, 5.4 rod, .047” compressed gasket and 4.100” gasket bore, all plugged into the equation using the 11R 190 56cc C.C., I come up with a CR of about 9.54:1.
Whew, if you read all that, thanks.
Next concern, I don’t see how the hell I can put that twisted wedge head on these pistons. Is that common to have a deck clearance of .011”. Obviously I’ll be checking P-V relation but I don’t want to waste any time or money here. I was told by LMR, the TW 170’s worked with the scat kit. I’m sure a bunch of people have done this, I just need reassurance before I pull the trigger on the 11R 190’s.
Sorry for the novel, but I want to be thorough here. Someone please talk me down off the ledge. Lol
My last thing is how much room should I have between rod cap bolts and cylinder skirt?
