Ok guys, i want to mill the head of my n/a 2.3L mustang. How much do you mill? .050, .075, .150 Its not a daily driver, its a road course car oh BTW the sn95 T/B swap is awesome, talk about your top end charge WOW.
There's no one answer for this. It depends on the pistons you use, head gasket, deck clearance, piston to head clearance, compression ratio, etc. Talk to a very experienced builder of the 2.3 or find a recipe that you want to copy and get the full specs on it.
as per the rules the bottom end is stock. it is all new though. the head has a little porting and you can only use the stock cam. i have heard of the others milling but i can find out how much.
Read. There is plenty of write up on these motors in the Hobby Stock magazines, on the internet, etc. Zero in on the engine build articles. Be sure to look some years back.
