I used to drive this car back in the day but mine had a 318, now I found another in pretty good shape only hangup is the slat six not thats it bad... I just want alot more power!!!
I would really like to drop in a built 360 pushing 400+ h.p. with a 727 tranny, dana rear end... you guys know what im looking for a street/strip hotrod.
I can honestly say I have no real idea where to start...
anything you guys can help me with would be greatly appricated, I will also be needing the motor/tranny/rearend if any of you guys has them up for sell...

Your local wrecking yard will be the best bet to find a motor and trans. Try and stay with the 727 although a 904 built properly will do the job. My preference is a La style motor over a magnum, but again they both have their advantages. Schumacher motor mounts will have the proper mounts. You may have better luck finding an 8 3/4" rear end over a Dana. The 8 3/4 is plenty strong for the small block and even stands up well behind a 500+ horse big block including hemi's. Good Luck

thanks alot for your imput! and I agree I really do want the 727 over a a904 even if its built. I heard you could accually use magnum heads on a early block is that true? im just asking because the guy accross the street from me just started to part out a late 90sdodge truck with a 360... offered me the motor lastnight for $200.00 bucks! he also says the rearend is a dana 60!! which I dont dought as I checked online lastnight and several dodge trucks have them, but if it is whats it worth? whats a far price on that?
and again I really appreciate your input!

sweet!!! just need to change out pushrods! ok, what about going carbs instead of the EFI currently on it... I would really prefer going this route instead of using the EFI.
alright, this may seem like a dumb question but please bare with me here... Is there any issues or do I need a special conversion kit for the newer block to the 727?
I need to redo the entire electrical, any one have an idea where I can get new electrical harness?
appricate all you guys are doing for me! I'll get some pics up of the cars current condition soon.

I once changed the K member in a 1982 New Yorker to upgrade to a V8 and with the torsion bars and everything on it it is a heavy sob, I recommend Schmucker mounts, a little price to pay for skipping a ton of heavy work. If you find a police package volare, gran fury or diplomat in the salvage yard I would pull the torsion bars, antisway bars front and rear, leaf springs and heck the rear axle too, the 8 1/4 is plenty strong for any 360 and ALL the police package furys and diplomats came with 2.94 sure grips and 11" drums from the factory but check it to be sure somebody didn't change it, you could even pull the k member if you don't want to spend $150 for conversion mounts it just depends on how ambitious you are. The 8 3/4 swap is not dead nuts on, the closest thing is a 8 3/4 from a b body and when I measuered for my car there was 3/4" difference so my opinion to just sticking one of those uncut in there is hamfisted at best, yes the bushings will flex enough but it is just red neck rigging at it's worst. I used the larger front discs off a 1979 Dodge St Regis, 11 3/4" as compared to 10 7/8" on all f/j/m bodies to go with the 11 inch drums in back, you can't have too much brakes cause getting the turd stopped is more responsible than launching it forward at warp speed, saves lives that way and less blood to clean off it, trust me. I am no fan of the magnum heads at all, has everybody forgotten how chevy's were notorious for plugged pushrods and smoked balls and rockers? Plus I have seen magnum heads in person and the ports don't look so great to me, maybe if you spent a year porting them but they are still just inferior design with the oil through the pushrods and no rocker shaft, plus a machinist friend of mine said that the magnum heads are notorious for cracking, he told me almost all magnum heads they magnaflux are cracked. I over heated a 1984 318 police engine so hot one time that I burned huge holes on two pistons and the grease on the outside of the block was trying to flame up, literal fire and a machine shop bought them from me with the deal he was going to magnaflux them then he would pay me or bring them back, well he never brang them back and his check cleared the bank. I would go with J heads with hardened seats put in(use only a very, very, very competent machine shop for that trust me), or the heads from a early to mid 70's 360 for factory hard seats, as the seventies progressed the exhaust ports slowly but surely shrank. I gave a fancy looking BMW sports sedan a neck and neck race to 70 mph (we had to let out we were in city limits) with my 1984 Fury hi po with a stock 318 police engine except for I had very lightly ported the 360 heads and stuck in the 268/272 450/455 mopar cam and cheap headers and dual ehaust, everything else was stock on it. If you are going to rebuild the 360 I would recommend sealed power 116cp pistons, for god's sake save yourself the misery of Keith Black hypereutectic pistons, they are detonating ring butting pieces of junk, I have a set on my shelf with chunks gone from the top of them cause the rings butted and tried to rip the top off the piston and I had even given them the ridiculous almost .040" ring gap the instructions said to, I have never had a problem with the 116cp from sealed power pistons. Definately use moly rings your bores will thank you, why do you think newer engines last so long? Moly rings. I have torn down lots of 318 police engines with over 200,000 miles and no ridge at the top of the bores cause they put moly in the police engines. Run the mopar 268/272 450/455 cam as a minimum, if you want more then go for it, just don't get carried away. Oh and put 2.02 intakes in the heads. With the mopar cam above you can expect at least 360 hp without breaking a sweat but over 400 is quite possible with say the 284 484 mopar cam but you better have a high stall convertor for the weighty Volare, Mopar Performance has some real nice cheap hi stall units that are economical but good quality. Even with the 727 I would put a shift kit of your choosing in it just to make it live a long time, nothing worse than wasting your weekend on your back with used junkyard trannies. Well there's a bunch of hopefully useful info, if not print it out and wipe your butt on it. Good luck and happy Moparing.
