Are the bores different at all on these? From what I read all the bores are 3.780, had a set of pistons that by part number say they are 3.810 which would make them 0.030 over but they aren’t stamped .030 over, don’t have caliper to measure them, but they fit right into a stock 91 2.3, are they just actually not .030 over pistons or was the 91 block bored out at some point? Motor only had 91k on it, pistons are for 5.7 rods and from what I’ve seen cant order stock bore pistons for 5.7 rods. Also motor had a 8 plug head on it, worth it to plug off Intake side and put a carb intake on it and run it like that?

Hello I’m new to compacts but wanna build a 2.3,does anyone have any updated info on building these before I read 70 pages from 10 years ago? I currently have a 83 2.3 with a lil rod knock and a good 90 2.3 and was planning on shaving 20 thousandths off the 4 plug head and putting it on the newer bottom end with arp studs, the 83 distributor and a msd box. Also thinking about using the newer cam and rockers or should I just get a aftermarket cam? I also have a 3 speed with linkage is that the right 3 speed? What bell housing is easiest to use?
