I have a 1966 chrysler new yorker with a 440 bigblock and 727 torquefligh transmission. Im planning on doing a complete overhaul of both and looking for around 500hp or more if possible.  I was curiouse what parts i should use to achieve this, i plan on completely "restoring" the car as well with a front brake disc conversion kit, entire new fuel system. so im starting from scratch and can build what i want but i just dont know what i should put into the motor to achieve atleast 500 horse.

My Daddy always told me there were three secrets to making horsepower. The first two were cylinder heads. The third and most important was cylinder heads!

What fuel do you want to use. How are you going to use the car? How docile or radical do you want the engine?

Performance 101... the engine is just a big air pump, what goes in must get out efficiently... find a good quality machine shop, not just the local yokel, I highly recommend LaRoy Engines out of Challis Idaho, talk to Jim & Cody... Like IQ52 said.. "Cylinder heads 1st & foremost", any type of port work will help a BB wedge tremendously, they are known for being the choke point hp robbers for the engines performance capabilities, then a better fuel system & larger pick-up & lines {more fuel delivery}, better camshaft with more lift/duration, with matched springs retainers & lock, w/good seals, "that will suit the engine intended usages", more compression, "actually good round bores" & better sealing rings, a hotter electronic ignition system, distributor & hotter coil {like CEI Distributor & orange box at a minimum} & ultra-low ohm resistance spark plug wires, a free flowing 1-3/4" to 1-7/8" headers & a free flowing mandrel bent tubing exhaust system 2-1/2"min. to 3", with either an X or H-pipe, a good induction carb & intake suited/matched carburetor cfm/size for the engine combo, a good free flowing gauze type air cleaner {like a K&N X-treem} with a 440 500hp will be relatively easy if you use that as a guideline, especially porting the cylinder heads or buying better flowing, intake & exhaust ports & combustion chamber size/design heads to begin with, then tune the combo properly, 500hp with 383-440ci easy peasy...

Then too, very important. What is the budget?

Yep Budnicks, we're adopted automotive twins, 'cept you like to type longer answers than I do.

thanks for the info, what do you think about just replacing the heads all together with 88cc aluminum performance heads from edelbrock? and 500hp was just a baseline, im hoping for upwards of 800-1000, but i dont know if the block will handle all of that untill i get it taken to a machine shop

So, if I understand correctly, we are gonna stuff 800-1000 HP into a '66 Chrysler New Yorker and drive it around on the street?

I think we should start with the 500 HP 440 and plan a whole new engine for the 1000 HP, unlimited budget project.

What do you say?

When we start out to dream and build, we need to think and plan carefully. A budget is extremely important, you may get started and never be able to finish this honor to your grandfather. What you want to do, can be done. I have built normally aspirated, pump gas 440s in the 500, 600, 700 and nearly 800 (787) HP range. With Pro Chargers and turbos you can drive the street and get 1,500+ horsepower to the REAR WHEELS, but the car itself needs to be prepared for the stresses put to it in high horsepower applications. 500 HP will be a very radical ride in a 66 Chrysler New Yorker, something like trying to steer an arrow. Proceed with caution.

thats why i posted on here was for advise so i didnt get buried in debt, i said no budget simply so that i could get answeres without money being a factor, even though it obviously will be a major one.  im thinking to put it between 500-700 horse and not much more and definatley no less.

For 500-550 horsepower, if you do all the assembly, your looking at $6,000-$8,500. Offset ground crank 3.90 stroke, h-beam rods, forged pistons, Edelbrock RPM 84cc heads, Edelbrock RPM Performer intake, hydraulic flat tappet cam 240/240 @ .050 .525/.525 lift, 750 cfm carb, roller rocker arms, good pushrods, after market ignition and distributor, headers. That's a good generic start.

i would much prefer a roller cam, i understand that its much more expensive but id rather have one than a flat tappet, i do know that the lifters and cam from comp cam is about 1500-2000 dollars (main cost is in lifters)

$6k for a 500 horsepower 440?  no way lol!  not when you can make a 400 hp 318 for less than 2k.  

for that '66, i'd do what the others said and get some GOOD head work done.  add in a cam, headers, and a decent carb and you can easily be in the 500-550 hp range.
