The parts I have are: New 4.375 stroke K1 Crank still in original box and in the original protective wrapping. Has chevy rod size and stock Chrysler Mains. 8 bolt flywheel flange. New K1 Carillo H beam Rods, new in the box. 7.10 length w .990 pin size Zeeker Aluminum Heads. Max wedge port...

Did you ever swap over to the TF240 heads? From what I've seen on the dyno the TF heads would be worth 50 to 100 hp depending on the rest of the engine. I've seen a couple 700 hp pump gas 470 engines with OOTB Trick Flow 240 heads. Never seen Stealth or Edelbrock heads anywhere near that number.

First I've heard of seats dropping out. They have had issues with the stock 7° locks in the past. I went 10° locks/keepers, cnc ported, stock valves, and spin in to 6k often.

First off, what are your goals for this build? Seems like it's primarily a street engine, but how heavy of a vehicle are you putting it in and what gearing are you going with? The 413 is just a 440 with a smaller bore (with thicker walls) so aside from the big valve heads, all the same 440...

I have TF top end with TF HR cam and Howards lifters 91767 on a new 440 build. I recently had multiple emails back and forth with a tech person at Howards. He said those Howards / Morel lifter must be at 380lbs open no more no less (design limit for that lifter). That is what they can take and...

At that point, maybe you should consider a stroker kit from 440 Source?

Headers? what cam did you use? what is your engine vacuum at idle?

I use the NGK plugs also. I would start at heat range 6 and then check the plugs to see if they should be hotter (5) or colder (7) I opt for the slightly shorter ISO plug length 1.98" (BK) vs the JIS 2.086" (BC). Gives a bit more clearance on cylinder #4 to inner fender on my 440 block with...

Ok so overall the kits from 440 have been pretty decent and reliable?

For sale is my 1970 Super Bee. One of 599 440 six pack 4 speed hardtops made. It’s a pretty basic bare bones muscle Mopar, with manual steering and brakes. Just buckets, tic toc tach, AM radio and the hi impact FC7 Plum Crazy paint are the only options that the original owner ordered in late...

My bet is the answer lies here. Dry threads. The torque wrench would show the correct reading. But the fastener wasn't stretched far enough due to the friction of dry thtreads. If the head and block are flat and undamaged? A new gasket (I like the Fel Pro 8519 idea in this apllication) and...

Hi all. I have done a bunch of reading in the million threads and think I have a general idea of what I want to do based on my budget, but figure some input from folks with experience would be good before diving in. My 440 is fully disassembled and has been inspected, it appears serviceable...

The motor has 440 Source heads. You think this could be part of the problem? I have TTI headers but they need cleaning and Im trying to get away from headers.

Didn't you give the shop a piston to work with and the specs before they machined it ??

A friend convinced me to at least partially assemble my rough 67 GTX while still working on trying to do a decent job on my 68 Coronet. The thinking is if I can get the GTX to at least run and move under its own power it will be easier to sell if/when the time comes. The plus side is we can...

So you are not using raised port heads on a 1969 B Body Coronet in combination with the 440-218 TTIs? As per the TTI website the 440-218s are not designed to be compatible with 440 Source Stealth heads which are on my factory 440 block. Do you have a part number of this Summit mini starter so...

The 4.25" stroker kits (505" @ 4.350" overbore, or 512" @ 4.375" bore) are pretty easy to build. The crank pins are 2.20" GM size, so the rod big ends usually clear the bores without needing to be notched. I haven't bought a Stroker kit from Hughes, so I can't comment on that. Got CNC heads...

In another thread, I’ve asked for and received help on my car which turns out had a lifter failure. In this one I’m going to solicit some advice about changes I might make when it goes back together. The car itself has great pieces- TCI 727, 3500 stall and Dana 60 with 3.91 gears, all of which...

I did not, I have Trick flow 240 heads on mine, not sure if that makes a difference compared to 440Source heads or not.
