I recently replaced my cam with a .550 lift solid roller cam. .587 with my 1.6 rockers. I measured my piston to valve clearance using Comp's checker springs and a feeler gauge and with .020 lash I have .250 clearance on the Intake at 10* ATDC and .266 on the exhaust at 5* BTDC. That was a lot...

I’ve had a lifter tick ever since my engine was new. I did all sorts of adjusting and never could get it to go away. I finally bought a second set of Comp lifters and replaced them. I used Camshaft Lube, Break in additive, and assembly lube all from Comp. I fired the engine and ran it between...

Had my 440 tuned on the dyno today and drivability really improved but my numbers are a little below what I expected. About 350 HP and 405 ft lbs at the wheels. HP begins tapering off around 4500 and drops at 5500. Is this about right for my combo or do I have an issue? My setup is as follows...

Just got back from the scales. the Duster weighed in at 3440 Lbs with half a tank of gas and no driver. Front end weight with 170 LBS of driver in the seat was 1970 LBS. Rear was at 1650. Thats not too bad of weight distribution for a big block car. Especially for a 4 speed. Here's my set up...

Well I have been trying to tune my freshly rebuilt 440 and for some reason I cant get it to fire when I shut it off once I have it up to temperature. It will crank all day long just wont fire. What are some things that could cause this. Another problem I have been having is that my engine will...

I have a freshly broke in 440 that I'm trying to find some good quality oil for. In the past I have tried to use synthetic motor oil but I had read somewhere that it is not a good idea to put synthetic in a freshly rebuilt motor. Is this true? Question 2, I have a custom ground cam and was told...

Well I finally broke in my 440 today with minimal problems. At least nothing major. First question. Some how I am getting oil on top of the valley pan towards the back. After running the motor for 20 minutes I had a nice little puddle and it was dripping onto my headers. Any ideas on where this...

I have a holley 4160 750 carb that I am going to run on my 440. Before I break in my motor I want to have it adjusted to run a little rich. I was planning on putting it on my 383 to get it adjusted so I know its good before I put it on my 440. My question, If I have it running a little rich on a...

I've had a rough idle on my 383 ever since i got it. It seems to rock back and forth like it has a misfire but when I pulled the spark plug wires one by one I couldn’t find a cylinder that wasn’t firing. I adjusted the carb yesterday and it runs a little smoother but still not quite right. I...

I am getting ready to fire up my 440 for the first time but want to be sure to do it right. I have too much time and money in this to mess it up. Here’s the specs, 10.7 compression, stealth heads, rpm intake First question, I have ceramic coated Schumacher headers installed. I just spent the...

The title sums it up. Do I need to use a gasket above and below the windage tray or is putting one below the tray enough?Should I just use some rtv? Application- '77 440 with a 187 pan and 440 source windage tray.

I have a custom ground camshaft and I dont know alot about what all the numbers mean. Could someone break it down for me and tell me how it'll run with my combo? It's a 77 block with a 69 forged crank, stock rods, kb237 pistons .040 over, 440 source stealth heads, 10.7ish compression, edelbrock...

Well, the title pretty much sums it up. I'm about to drop in my 500 HP (Hopefully) 440 and I hadn't thought about beefing up the frame. When is it required? If I get frame connectors do I still need torque boxes? Who makes a decent set of these. Preferably a bolt in set. I'd also rather not cut...

I've been searching threads and cant find much info on what I need. I'm about to drop a 440 4 speed inplace of my 318 3 speed. Will the z bar I have now work as long as I get the ball stud bracket I need from brewers? Or do I need to get the modified torque shaft as well. The only info I found...

I'm rebuilding a 77 440 with a forged 6 pack crank and hyper pistons (KB237's). Am I safe just getting the stock 77 rods resized or should I buy new? If I need new please point me in the right direction.

Before I get it all together and Find out I should've used a different part I want the pro's (you guys) to look it over. Here's what I got. 74 duster 3.55 rear end. 4 speed overdrive 833. Rear wheels about 25" tall. Car will be driven on the street but will go to the strip occasionally. 77 440...

How much power can a 77 cast crank and rods handle?

My machine shop told me to go with kb237 pistons and a MP purple camshaft for my 440. Any opinions on these? I'd like a little more info on what cam I need. Hydraulic, mechenical, What duration. So on and so forth. I need something streetable but I want it a little choppy. Suggestions?

I'm trying to hunt down parts for my 440 build but I'm hung up on heads. I had planned on getting the stealth heads from 440 source but was told to not waste my time and go with eddy's. I don't doubt that the rpm heds are better. But they also cost almost twice as much. How much more power will...

I just pulled a 440 out of my 77 new yorker and I'm now making plans on how to build it up for my duster. I found some cheap aluminum heads on 440source.com for $900 assembled. PN 200-1055. Are these any good or junk? What would be a good cam and intake to match up to these heads? This will be...

I picked up a complete duster minus engine/trans with the intension of dropping an engine in and having a driver for awhile and eventually reselling for profit. I then bought a 77 new yorker with a 440 727 combo with intensions of using it as my donor car. The engine runs good, No knocks...
