Anyone using a 500 stroker kit in their 440?

Why not try adding a good package with heads (edelbrock), a cam, intake, and carb. Then see where that gets you? It would be a lot cheaper and easier to install too. Besides if you add a 440source kit then you'll need all these things anyways to get the most out of it.

I have a 440source 512 kit in my 440 and it runs very good. Machinist liked everything when putting it together except for the main bearings. Just stay away from their water pump and housing..

Using stock replacement pistons has most likely been the 'bad' decision during the earlier build-up I would think.
You probably ended up with less compression an above that the, I suppose, composite headgasket used lost you some more compression. With stock pistons and open chamber 906-heads you won't have any pistonquench either.
You could try to advance the cam to see if you can build some more cylinder pressure at low rpm, but don't expect much from that.

i agree with Randy, but in the end, you 'know' you rather want that stroker motor under the hood

I'm running a 500" in my heavy 1960 NewYorker.
Stock Edelbrock heads with shorty headers into a 2.5" dual exhaust. It gets 17mpg with the 3.23 gears in the back, but still roasts the 275/60-tires through first and second gear. With a stroker you don't really need anymore gear in a street car.
Oh, my heap runs 8.6 on the 1/8 mile.

I had a quick question regarding what carburetors you guys are running on your 500+ strokers.

Would an 800 Thunder Series Edelbrock work well?

Thanks.

Low compression? Mild cam? Need power?




maybe

I was hoping for an affordable street motor that made decent Tq/Hp.

Thanks for all the tips. I know I'm missing something somewhere. I'm kind of stuck with the converter since I sent the wrong core to be rebuilt and ended up with a 19 spline that I could only find one converter for from Summit. With the AG hood I'm kind of limited on space. I don't know if I could squeeze an RPM Intake in there. I already have a chopped and lowered fiberglass base plate. I think I will check my timing, it may be off also. I quess I should re group and start with all thew simple stuff first before I go and spend a bunch of money.

Which stroker kit, the 4.15" or 4.25".
I have a 440 source 4.15" stroker kit on a 400 block (499 cid), and I am about to start building my 4.25" stroked 440 in 0.030" over, so it is really a 505cid engine, but uses the long 7.1" rods.
The 4.15 kit went in pretty easy, only had to take a small amount off the oil pickup boss for clearance.
I am hoping the 4.25" kit in the 440 drops in without having to clearance the block? The 7.1" rods use the smaller chevy rod bearing size, so that should help with the clearance issue.
The 400 with the 4.15 kit is more of a high RPM hot street/strip combination with 12.4:1 compression (using the flat top pistons), a decent sized roller cam, and max wedge victor heads.
The 440 with the 4.25" crank is going to be a milider street engine, 10:1 compression(the 17cc dished pistons), hydraulic FT or hydraulic roller cam, and the 440 source stealth heads (I want the look of stock heads.)
With 500 cid, the 906 heads will limit performance. I have even been thinking of getting the stealth heads ported for my mild 440/505 engine, but I doubt I will as the car that engine is going in won't be raced, mostly just street driving/crusing.
