80's 360 in a 60's mopar

Early oil pan wont work. You need a 360 specific CAR pan AND pickup. Also, your early A will need the V8 centerlink with the dropped center. Exhaust will probably be early 273 as I don't think the later Dakota manifolds are proven to fit (stand to be corrected here). Thin head gasket isn't going to help much...maybe .1 or.2 more comp. You'll also need 360/early A specific motor mounts....273's won't work. 273 distributor is fine. Use the early 273 timing chain cover and water pump to avoid having to change your rad inlets and outlets. While you're in there, you might as well install a true dbl-roller chain and sprockets. You can run the 360 2 bbl if you like, but a 340/360-port size aluminum intake and 600-650 cfm carb. will perform better. E-4 cam is too small for a 360...they are better suited for a 273 - 318 tops.

I'm sure more peeps will chime in with more info.......
