Goodday, Iam in the process of putting together a street/strip 360 for my demon. This is my first small block and iam pretty much clueless. Ive owned b/rbs my whole life so its gonna be an adventure. I pulled a 35k 360 fron a 1985 d350 that runs exellent. Iam not trying to make 500 h.p. just something to push my 3200 lb a body into the high 12s low 13s without to much trouble. I really dont wanna tear into the short block but iam sure the comp. ratio sucks so I may have to. I figure 350 to 400 h.p should get me close to where I want to be. So what heads,cam,intake would you use? I have two 318 magnums laying around so if the heads on that would help I got them. Any suggestions would be appreciated. Thanks for your time.

The heads and the rockers of the magnum would be a great choice actually the best IMO "in terms of stock heads" RPM air gap intake.headers and a nice came some where around 233 @.050 and .485 lift. Try to get the thinnest head gasket to bump compression I think there used to be a .028 but it is hard to find. Keep in mind the magnum rockers are 1.6 ratio when choosing a cam. Also you might want to get the guides cut down.

Thanks! When swapping on the magnum heads,which pushrods should I use? I remember reading somewhere that the magnum heads are oiled diferently than the old school la heads. I also remember they respond well to port work. Iam no porter by any means but iam capable of some minor gasket matching and cleaning up the bowls. Is it worth the aggravation? Or just bolt them on and gas it!!!!!!!! Thanks again!

Use pushrod oiling and the best bang for the heads is to do the bowls and just clean the runners

That would depend on how much you want to raise it but the thin head gaskets might do what you want... you need to sit down and think out your out come and budget... but if you go with the magnum heads you might want to have them trued up anyways so that would be the time to do any compression changes

Good Idea. I think just a small shave to true them up would be good. Iam trying to be budget minded. Iam putting together a 470 low deck and I would rather dump the money in that then to have a couple grand in a temperary engine. Thanks alot for your help! Nice car!!!!!!
