Leave the stock crank in my 440. 3.75 stroke.Or buy an eagle crank and stroke 440 to 505 cubes and 4.25 stroke. It is going to have max wedge heads and crossram and stock cast iron max headers. 9.5 to one compression. I should just do the 505 cubes .I think it will be more fun. What do you guys suggest?

The 505 cubes. My next one will be a 535 (30 over/4.5" stroke). No one that I have ever spoken with has lamented after the fact that they just have too much power

awesome, I am gonna do it. I just never had a stroked motor and just wanted too know what some of you dudes thought. It is going to be a max wedge clone car. The car will appear stock. But it should be a beast I hope. I have both sets 0f 3447 carbs or 3705 carbs. Will the larger 3705 carbs be better for the 505 cubes? I would think so.

Your my kind of guy . I would think the larger carbs would definitely be the way to go. I am going with some super stealths (they're bare but only $100 more than complete regular stealths & I already have a set of 2.14/1.81's sittin on the shelf. They do need offset rockers on the intakes & an external pickup for the pan which ain't no big deal

Dude, you do know that the rear tires are the limiting factor on how much power you can put to the ground, correct? I've owned and raced several Max wedge cars over the years, a couple of Street Hemi cars also . I ran both size carbs, the 3447 on the M.W. Stocker and the 3705 on the M.W. bracket car, the bracket car had a 440 short block and it had a full 12 point cage so it weighed about 250 lbs more than the stocker, it had a Dana 70 in it with big tires and wheels on the rear, it was right at .2 ET quicker and 2.0 mph faster than the stocker They where both fun to drive My last pump gas street and strip car was a 512 C.I. 400 stroker that started off with a set of ported big valve 906 iron heads and a stock type low deck six pak, it ended up with a set of Indy SR heads with M.W. ports and a single Dominator 1050 CFM carb. on it, it was a flat out blast to drive If your going to run stock type iron heads don't shoot for or use more than 9.5 to 1 compression My 512 C.i. pump gas stroker made 612 Hp at 5600 RPM and 644 Ft lbs of torque at 4500 RPM on CA pump swill back in 2003 with 9 1/4 to 1 true compression ratio with the 906 heads and six pak, yours will make quiet a bit more HP and torque than that with the M.W. heads and intake and carbs, trust me on that Get ready to live your dream or be scared to death

Definetly go for the cubes. I did as I made my 440 a 493 with just a 4.15 crank. And I tried to make my car look like a Max Wedge from the 60's. I want my eng to look close to a Max Wedge as I painted it orange but I only run one carb on an Indy dual plane intake right now. But I love it and I raced in a NSS class two weeks ago at the track. And most of the time the hood is closed so then it looks just like a Max Wedge. Ron

Here is my eng. If I go to a crossram it would look real close to a Max Wedge and might fool some people. But it drives and runs so nice with the single 850 DP and Indy intake. It will run 10.70's driving it to the track on pump thru the pipes. I have a blast driving the car. Ron

I be strokin. Hey that red 63 is awesome. Going to be using a Miloden circle track pan. I don't want it hanging down too far. Heard I will have to notch my K-member. I would rather just beat my pan in a little.

Don't want to rain on the parade but make sure your heads can support the cubes. There have been a ton of disappointed guys with 500+ inch strokers. There's at least one or two a week lately. Everytime it seems they build a monster bottom end and think the same heads that worked on there stock stroke should be just fine on the new motor. Do your homework. You can easily make 600+hp with stock stroke, less cash, your heads, etc.

Thank you for the kind words. I am using the Moroso oil pan and it has good clearence as the angle of the pic makes it look less but its a good 5 to 6 inches of room. And it fit in the K-frame with no cutting or modifying anything as the eng dropped right in. Been driving on the street since 2006 and the pan has never hit anything. Ron

So the only thing you need to stroke a stock 440 is a bigger crank?

I just rebuilt my 440 with stealth heads, cam, CH4B and 800cfm and am now wondering if I should have got a bigger crank if that's all it took?

You would need pistons with the wrist pin higher in the the piston(stroker piston).

Depends on your end goal.If you are going to run it hard,maybe do a little racing fine,if you want to just drive it and make it look pretty,put your money somewhere else ! I have a few friends that have them just for the "I've got a stroker wow " ! No interest but that's just me .

If you're going to be rebuilding the engine anyway then stroking it doesn't add much to the total bill. You need new pistons anyway so that is no additional cost. If you need a new crank then you're dead even, if your old crank was still good then you're only out the difference of a new crank vs. rebuilding your old crank. So maybe $300 difference for the extra cubic inches.

Adding the extra inches will lower the torque peak of the engine which is good for a street car. It might not go any faster at the track, but it will give you a nice thump in the back when you jump on it going up a freeway on-ramp.

Haven't completely reread the OP info to see if he's starting with a cast or forged crank. If cast, time to upgrade, go stroker for no extra cost. If forged, resell to a guy that wants to cut it down for a 400/451 build.

Strokers/torque rule on the street!

Just playing devil's advocate here, but I was racing against a guy with a full interior '62 Belvedere a few weeks ago. He had a stock stroke 413 with max wedge heads, and the A&A repro crossram. He was running 7.35s all day long in the heat on 9 inch slicks. 1/4 mile times would be like mid-11s.

I am kind of on the fence about doing it now. It will only grow 65 cubes and that doesn't really seem like too much. But will there be a difference in rpm. between the two? The stroker motor will not rev as high will it? And I need a high rev to get the free supercharging from the max wedge intake and breathing system. Maybe I am looking into it too far. My car is a 4-speed -23 spline 8.75 axle 3:23 suregrip. And I want too keep my dog dish hubcaps and 14 inch wheels on Stroke it or not I know It will be easy to turn those tires over. I am not going to be going to the track with it. I just like to burn up the back roads Dukes of Hazzard style around my house and occasionally wax a mustang or ricegrinder or two. If I stroke it with the Eagle crank I was told I will need a new flywheel. Is this the only item I will have to swap out for my 4-speed set up?

Add the stroke. You will enjoy the performance.

Trust me, 65 extra cubes is nothing to sneeze at. The reason the Max Wedge stuff needed to be spun up rpm wise to work was because it only had 426 CID of air to displace. 505 CID is gulping 79 cubes more air every rev so it will take much less RPM to keep the air in the induction system moving at the speed where it is efficient.

You can't buy gas that a stock Max Wedge would be happy on but a 505 at 9:1ish should make as much or more HP in a 3.23 gear happy rev range and all that extra torque that starts at just above idle will make it feel much bigger.

Just do it. You will have zero regrets.
