My 360 Magnum build thread

Don't worry about a quench thighter than .039. The 360s not a big bore, the pistons are tall, you're running a steel rod, and you can go much tighter. If it was me I'd be aiming for .030-.032 for quench so I think you're fine. The less the quench distance, the better the more effective it is. On the bearings... You won't squich the bearings so much as stretch the bolts... This is really easy to do. However, if you have to replace the bolts, that rod needs to be re-sized.
Keep up the good work! (and welcome to blueprinting...lol)
