For a 440 RB block: 4.500" stroke. 7.1" rods. I'm sorta considering one. I would need the extra wide flange #3 main bearing (for my later block) and I wanted file fit rings

I built a 535, 4.5 stroke, 4.350 bore. It made a ton of torque with 906 ported heads. It can be built into a great street motor because you can shift at 5400 or so and maybe less for best performance. I was shifting at 5700 with a 590 cam and I may have been over revving it. The nice thing about that many cubes is the ability of running a very tight converter and a low (3.23?) rear gear and it will still fly. The key to making it live is keep the revs way down and be conservative on the tune. They also make great bracket motors if you want a very low rpm reliable deal. I believe the torque peak using the McFarland formula would be about 3900 rpm. This is not a motor to push over 650 hp, or big port heads.

I have a 4.25 crank with the 2.20 BB Chevy Rod size and journals.
It's pretty close on the oil pump pickup (within .050) and it still easily clears the bottom of the bores with no issues.
I put together my own "kit" using Molnar crank, 7.1" rods and Mahle pistons. It balanced really nicely with just a little weight being removed from the crank. It was also cheaper than the source kit and utilized, IMO, better rods and pistons.
The Molnar stuff is very nice and dropped in with no fuss!

Cons ... external oil pickup lines because the stroke is too long to clear an internal pickup tube.

I would need the extra wide flange #3 main bearing (for my later block) and I wanted file fit rings If the crank doesn't have the extra wide flange you don't need them , the normal flange fits that block just fine ... and good luck finding them if they are anything like the low decks ... not made anymore.

Thanks double R, its been on hold for quite awhile but I will check into that & see what I need to do/not do/change. it is a pricey deal & I did already grab a bolt in pickup for external oiling that 'source had on (clearance) sale for dirt cheap (not a big start but every bit helps) & the one guys' post on the cheaper Molnar crank/Mahle pistons deal sounds worth checking into especially since I wont be racing it, just an occaisional street blast

Even if you have the wide flange crank ... which I doubt it is ... you can use a narrow flange bearing , it won't hurt a thing.

the block I have is a 74 with the wider flanges. it'd be the 'source kit (their crank). iirc I asked em about the later bearings which were extra. just not sure at the moment if 100 extra cubes is worth a 2K (& then some) $$$ outlay

Haven't done a 540 but we have done 3 of the 440 source 512 RB kits. I like everything about it except I wish the rings were a little racier. We are gonna try the stealth heads on the one we are doing now.
