In the process of putting a plan together for my slant. I’ve read a ton on here and the info is priceless. I want to raise the compression on this engine. What determines if you mill the head or the block or both?
There are no pistons for the slant 6 to raise compression using matched factory parts. Unless he wants to use the 198 connecting rods and Chrysler 2.2 4 cylinder pistons, the only way he has to raise compression is milling the head and or block, OR expensive custom pistons to match the 225 connecting rod length and crank stroke. Milling is by FAR his most cost effective option. There'd be no reason he'd need to "put it back" anyway.Just remember that whatever you machine off of the block or heads, you can't put it back. If this is just an exercise in upping the compression, do it with pistons. Just square the block and heads, flat and straight.
Sorry for the x, but the Slanty pistons are already heavy enough for the bore, and long as a can of baked beans as is! Lol!Just remember that whatever you machine off of the block or heads, you can't put it back. If this is just an exercise in upping the compression, do it with pistons. Just square the block and heads, flat and straight.
if one was using long rods and 2.2l style pistons and followed the instructions sequence in post #7 they would certainly notice that the pistons were at or nearly at 0 deck height prior to milling the block.You didn't say what the goal & budget is, as long as You are NOT going to use the long(198)rod/ 2.2 piston combo, the above is accurate. You have to modify the amount that can/should be taken off the block if You go long-rod...
They are close before milling. Yes.if one was using long rods and 2.2l style pistons and followed the instructions sequence in post #7 they would certainly notice that the pistons were at or nearly at 0 deck height prior to milling the block.
Got a part# for those gaskets?Whatever you mill ... you CAN put back by means of a cometic/mls head gasket.
I'd mill .020-.040 off the block and .060-.080 off the head.
Custom. 180.00 bucks.Got a part# for those gaskets?
Certainly so Sir, thus impressing the importance of making goals, decisions, & detailed checks before doing anything...if one was using long rods and 2.2l style pistons and followed the instructions sequence in post #7 they would certainly notice that the pistons were at or nearly at 0 deck height prior to milling the block.
Well, that ain't too bad for a mulligan......Custom. 180.00 bucks.
Had some made @.080
Nightmare at the machine shop years ago.Well, that ain't too bad for a mulligan......
Mine were .055" below the deck surface. Not anymore. lolif one was using long rods and 2.2l style pistons and followed the instructions sequence in post #7 they would certainly notice that the pistons were at or nearly at 0 deck height prior to milling the block.
