building a mild Daily driver 318

Well after doing a lot of research on line and talking to a lot of mopar people add the casting 302 last digits on the casting# these will take the 188 and 160 valves and then get the P434 9557 Mopar head gasket these are thinner 0.40 the pistons in the 318 can be any where from 30 to 80 thousands in the hole from top dead center just remember the thinner the gasket it might throw the intake off a little that just means machining the intake to get the bolts to line up. Just to let you know the 302 are getting hard to find but that depend on your scrap yards that you have available and also these have the hard seats for the exhaust valves early 318s heads do not.I am dealing with all this as i write this. I have found the 302s and having them done this month. The cam is going to be a comp cam but we have not came up with the numbers yet. Just a dual plane intake with a 600 cfm carb with vacuum secondary is what i have coming. Performer intake everyone has an opinion on intakes just remember a dual plane.To get more dual exhaust i was told either way headers or manifolds.I went with 2.5inch with headers. The motor I am using is a 67 that someone had gone 30 over on the pistons but did not know mopar had the issues with compression right from MA Mopar so that is why i am just changing the heads and adding the 4 barrel and duel exhaust. With this all being said hoping for 330 HP will not be able to dyno it till spring to fine tune it up. So i am also dealing with The 8.75 rear end the A body cars have the lousy 1 1/2 drum brakes. The drums are getting hard to find for these and if you do find them it would cost just as much to put Disc brakes on and then the rims are also a pain 5 on 4 inch to put decent rims on you have to up grade the axles to 5 on 4.5 $400.00 and another $ 400.00 for the larger drums or disc so if the 8.25 is good enough go that route. Does not cost $800.00 to $1000.00 to have a drive shaft cut down and to mess with old crap when modern stuff is available. And all this is for the love of a Demon.Good luck
