Flywheel install adatper/cone???
 

Finally warm here in Wyoming. I’m finishing the last pieces of the build. I ran into a problem though. Flywheel doesn’t matte up. Is there an adapter I need for an after market wheel ? No way it will fit over the ring in the picture .

as a refresher. Here’s the link for the 454 build. My wife went back to Mayo Clinic again but makes progress every day…albeit very slowly.

Flywheel is a ram billet steel 168tooth neutral balanced wheel.

You need a flywheel for a one-piece rear main seal. The one you have is for the older two-piece seal style crankshaft.

It's supposed to be for a one piece rear main seal. Here is what I got. Ram 1550 Also, I saw that one you linked is for external balanced engine. Mine is internally balanced. Not a big deal though.

I think I figured out my issue. I ordered one with a 0.4 inch larger center bore. Ram-1550X

The 1550X is an LS flywheel, not for a big block.

Pretty sure you need either a Ram 1501 or 1502 depending on if you want 30lb or 40lb. A stock GM flywheel is about 32 lbs. I actually weighed one today for someone.
The first two on this list:

well crap! I really should pay better attention.

It happens. Big projects, you'd be hard pressed not have some mistakes here and there. Limiting it to minor things is the trick.

For sure. I took my time. This is the flywheel I need. My motor is internally balanced.

Tartilla,

I hear this.... I bought a Livorsi oil temp gage to match all my Gaffrig gauges. :rolleyes: Still haven't got it sent back yet.

Thanks. Brad.

This doesn’t fit either. To small. Been super sick and finally got around to taking it out of the package. Time to buy a bunch and see what fits then send the others back

That flywheel is not correct. It is for a one pc seal Small Block You need one for a 2 pc seal small block or any big block. If you want a Ram it will be the 1501.

I have 1 piece rear main seal.

I updated my post, auto text turned “ bunch” into “gun” for some reason. Whether the flywheel is for a single or two piece seal I don’t think matters much as the balance does. The 1501 is one of the 4 I bought.

I understand that but yours is a big block. All of the Big Blocks ever made, both 1 and 2 pc seal are the same size where the flywheel bolts on. The only difference is the balance. They are also the same size as the older 2 pc seal small blocks.
The only 1 pc seal cranks that are different are small blocks. Believe me the 1501 is correct. If it does not fit then something else is wrong. It might be a little tight, they all are when new.

Do you have a good way to measure it and the end of the crank ? I just measured 3 different Big Block cranks. One was a 1 pc seal 454. Another was a 1pc seal 502 and one is a 2 pc seal 396. All three of them measure just about 2.485" I also checked an older 350 2pc seal crank and it is the same.

The one in the picture is a 1 pc seal Mercruiser 502

Here is what the inside diameter of the flywheel measures. You can see its only a couple of thousandths difference. This is a used one and has been on and off a few times. Like I said the new ones can be a little snug. See if you can measure the id of the 1501.

I will add one more thing. I have been really disappointed lately in a lot of aftermarket parts so it would not surprise me a single bit if it is made wrong :( :(

I seem to remember having a problem with one last year but cant remember if it was a Chevy or a Ford and what brand flywheel it was.

I’ll measure when I get off work tomorrow. I’ve got digital one I used to measure pushrods

Bat,
I remembered which customer was having the same problem. I just called him and his was a RAM flywheel also :( He sent his back and got a McLeod one that fit perfectly. I guess you will find out when you measure it.

didn’t get off work till late. I work tomorrow too. Gota measure it because all the flywheels are here. Hopefully by Sunday that mess will be over.

there we go. 6.316cm in metric. The 1501 is correct. I love this forum! Everyone here is so helpful.

So the 1501 went on ok ? Glad to help :) :) :)
