I’m building a 2.4 to put in a gravel Mk2 Escort and just have one question I can’t seem to find a definite answer on. I’m using a 2.5 Mazda 3(Australia) block, a 2.3 Ranger keyed crank & Supertec 2.5 pistons. Can I use any off the shelf aftermarket 2.3 H-beam rods(will they be the correct sizes Andy lengths?), or do I need custom?
Hey mate, i am also on this journey and keen to know what else you have found out..if your happy to share
