Well, heavy metal, enough of it, 'will' fix it, but if it's truly "way out of wack", and if particularly a cast crankshaft, I would question the advice of the effort or expense?      :-\
 

Great feedback on all of this! Yep, my thoughts exactly. I guess we will see what he comes back with as far as how much heavy metal it will require and go from there.

The sad part is, this was supposed to be somewhat of a budget build for my brother's 63 unibody truck, which is to be maybe 450 hp. Nothing too radical. In hindsight, I probably could have or should have just gone with a 3.98 stroke or 4.125 to help reduce the offset. It's been very tough to get any parts during Covid, so we have really scrambled even to get the parts that we have. So I'm really hoping one way or another it works out. I'm not afraid to add Mallory up to a point. But, as an example, if it goes past say $600 in mallory, then it would have made more sense to just get a forged crank. But we are kind of stuck with it at the moment.

Thanks guys!

I want to first make it clear that I'm not questioning the shop. If that's the way it sounded, that was not intended. This is a shop I have used a lot and I like them. I was just asking generally if is expected to add Mallory to the cast 4.250 cranks and if it's a lot. It doesn't surprise me at all that it would be the case.

One thing I found after I have started weighing the components is that the rods and pistons were heavier than I expected. The rods (I-beam) are 840 grams and the pistons are 620 grams with the pin. So maybe that is a problem. I do have a set of Eagle h-beam rods that are 810 grams. So that may help.

At this stage, he seems to be concerned that it's "way out of wack" and he's unsure if Mallory will fix it. His balancing guy was out today, so I may hear more tomorrow or another day. We'll see what happens. I'm pretty much just telling him, if it needs Mallory, it needs Mallory and I am fine with that. I could potentially use the H-beam rods and maybe get a lighter set of piston pins to help reduce the bob weight.

I have a Scat cast 4.250" crank at the machine shop now to get it balanced. They are telling me that the front needs a lot of weight added. He thought maybe we needed a counter balance spacer to add to the front. I told him it's supposed to be internally balanced. He seems to think it may take a lot of Mallory. Is this normal on these cranks? The components are all light weight.

I know on the Scat 460 based cast cranks, it's pretty normal to add a lot of Mallory. I just wasn't sure what's normal on an FE.

Don't forget hedman and Dougs both have a set of headers available for your fairlane .

Interesting... I just looked up the Doug's headers and they look totally identical to the Hooker headers only slightly cheaper. Makes me wonder if they both come from the same factory.

Nightmist66, that is a sharp looking Fairlane. I like it!

I guess we'll just keep an eye out for some headers that we like. I'll definitely check into the FPA headers. I also noticed Crites sells some, but I'm not sure on the quality of them.

Good deal. Thanks guys! Also Jay, I discovered your intake camparo book and I've been studying it. That's some great info! I've dealt a lot with 385 series engines over the years, but only have a little experience with FEs. But I am extremely excited to build one. I'm reading everything I can right now.

Right now the combo we are thinking of is something like this:

445ci stroker (or bigger if we get a 427 block)
MR Tunnel Wedge 2x4 intake with two 600 or 660 Holleys
11 to 1 compression (depending on a lot of variables)
C4AE heads with either 2.09 or 2.15 intake valves and 1.66 exhaust
Heads ported by me (I've done quite a bit of head porting over the years)
Solid flat tappet cam 250 to 260ish duration @.050" & .620"ish lift 108 lsa

This will be going in a 66 Fairlane replica of a factory 427 car. This car is for my brother. He had a 66 Fairlane with a 428 cj back in the 1980s and it's the reason I got hooked on muscle cars. He had to sell it several years ago and has always wanted a Fairlane again.

The heads are C4AE 6090G. The intended use will be street and strip. Probably looking at a 445+ ci with 500 to maybe 550 hp.

I thought I saw someplace that the hooker headers would not work with the 8 bolt heads.

We had a 66 Fairlane back in the 1980s with 428cj heads, with hooker headers, and it was quite a pain to deal with the headers. It would be nice to have some headers that would work with the 8 bolt heads and possibly be a little bit easier to install. But I also know some of the choices may not mix well with trying to go over 500 hp.

Hey guys, I am new to the forum and this is my first question. My brother and I are about to build a 66 Fairlane with an FE.

I am wanting to know which headers we can run if it has the 8 bolt exhaust flange?

Thanks,
Mike
