Just tore down and cleaned up my 70 B-body 8 3/4 rear. The housing has this terrible welding on it, yet the inside is as it should be. Looks like the flange washed out and it was built up with terrible weld. Factory???

70 440 electronic ignition, long tube headers. I bought MSD Street Fire wires many moons ago and am just now installing. They have straight boots on the plug side, and 6-90 degree 2-straight boots in the distributor side. Straight boots are only long enough to reach 2 or 4, maybe 1. Also, the...

Is there a special coil bracket for the offset (height) coil bracket mounting bosses on the edelbrock Performer? Or, do I just need to make a nice spacer? Thanks

Does anyone have the specs for a dipstick tube o-ring. Doesn't seem to be available as that part from the autoparts and I don't have time to order one online. If it is a standard o-ring size and material I may be able to get from grainger next day. Thanks.

I ordered Mr. Gasket header studs for my 440 906 heads and to my surprise they have no shoulder with a continuous thread from end to end. I know the shoulder is not a sealing surface, but I imagine the shoulder interrupting the spiral leak path would help with reducing the leak path. Any...

Is this seal just a metal “conical” washer, or is there supposed to be rubber molded on it?

Looking to replace the wheel studs from L to R hand thread since the disk brake conversion is R hand thread. Is the room to change the Rear Studs without pulling the axle?

Valvoline max life (high mileage) Dexron VI synthetic is really cheap at Walmart. Like 18 bucks a gallon. Planning to use Synthetic Dexron VI in my fresh 727 rebuild. What is the big difference between the max life and the regular Valvoline Dexron VI synthetic. Max Life advertises special...

I am using ARP Flex Plate Bolts, Torque Converter Bolts and Bell Housing Bolts for my 440/727. The only torque value I found from ARP was for the Flexplate Bolts (7/16") - 75 ft-lbs using their assy lube. For the other bolts they simply refer you to a spec sheet, which requires you to know the...

I am surprised at the huge range in prices for header bolt sets. I am putting Doug Thorley headers on my 440 (906 heads) in a 70 B-Body. What bolts do you all prefer and why? Thanks-

I am looking at putting some NOS pistons in my 440. They are NOS pistons, PN 3420214, correct for '70 (w) 4bbl......listed as 9.75:1 CR. I was told they are flat tops and the compression height is 2.000. However, when I run the CR calculations, I get closer to 9:1 with open chamber heads. I...

Does any one know if a 78 440/727 in an RV had a higher designed stall than a pass car application? Posting my RV trans to Craigslist and trying to decide if I should hold onto the convertor.

I am about ready to start my new motor up. Pump Gas motor, not looking to squeeze every last HP out of it. It is an iron head, 440 with ~9.3:1, 270/.470 Hydraulic cam, an 800 CFM Edelbrock carb and headers. MSD Blaster coil and a Procomp electronic ignition set-up. What plugs and what...

Looking to rebuild my first 727. Bought a video, read a book, have the service manual, read the great blogs here.... ready to do this. Lots of you guys have heavily modified and impressive transmissions. My car however is a cruiser, mild 440 build, hemi converter, likely a 3:23 suregrip...

I have received a couple of opinions to use a Hemi converter as a budget minded option and get a bit more stall over a stock 440 unit. Looks like this could run about $100 for a Daaco reman unit, plus another $50 or so for an aftermarket flexplate to accomodate the 10" bolt circle. Is...

Came across this max Wedge picture. Not sure who the individual is, but I enjoyed the old internal Chrysler picture and thought you guys might too.

Ring Gap for New Speed Pro L2355F40??? Bought an engine rebuild kit from Summit, which included a standard fit ring set for .040 over 440 (4.360). The ring set is ZE424K40, cast iron moly coated top ring, cast iron non coated 2nd ring. I am surprised at the ring end gap, which is .035-.036...

My car came with a 6 bbl style air cleaner (but not on car), with base to fit my single 4 bbl. I have seen some cautioning about checking hood clearance with a Performer RPM intake manifold. Does anyone know if a 440, with RPM Manifold, 800 CFM Edelbrock AVS and 6 bbl style air cleaner will...

I am rebuilding a 1971 440 that is riddled with aftermarket chrome fasteners and very few washers. I am not seeking an originally correct fastener rebuild, but would like to replace these chrome fasteners with bolts of the correct length and washers where originally used. Main concern areas...

So, now that you guys helped me decide to stick with my current cam, I need to choose a converter. Again, this car will be driven on the expressway a fair bit, plus cruising with family. Engine specs below. Currently a 2.94 gear, hoping to upgrade to a 3.23 suregrip soon. The coverter now...
