And no offense, you shouldnt be talking about how long it takes for someone to build their motor since your not even doing the build yourself
Not my point.

Ricky isn't building his either.

Spite is just a good of reason to NOT pick a part as "I know a guy" is to choose one.

Good luck with the build, it sounds exciting. Can't wait to hear how it goes. And if you are able to take Tony up on his offer, can't wait to hear about that either. Even if you can't test it under perfectly ideal conditions (efi intake) it might still be neat to see what it does with the different heads.
Thanks, if I could work out the logistics, I'd love to take him up...may not be possible. Not my call. It's a time/money thing.

Are you keeping the cam specs a secret? Isn't normal for you not to respond.

We talked about 232/238 112* but Pat wanted to put a little more thought into it. I called yesterday to get the final spec, waiting for the phone call back. It will be a split cam, custom ground, in the neighborhood of 232/238.....

If you dont need a small base circle they make a 234/240.

You're looking a bit more radical than I am. I want something that's a little more tame.

I think the block accepts a small circle base.

Default dart block

why have you chosen the dart block with the 2 pc rear seal. there are blocks that have the 1 piece seal. in all the motors i have built the 2pc seal eventually gives way to a leak. i have not had a 1pc seal leak in the past 5 years. also you will have to go to a flywheel that was not meant for the trans in your car. all this seems to add up to problems in the long hall. also would like to see what the emissions are on this when you finish.

Both are true. I have an auto, and we already have a new flywheel that will work.

I have no idea why Dart is making it this way....I am a bit concerned about the leaking...

I can't for the life of me think Dart would launch a brand new series of blocks that would have a two piece seal that would have problems.

I'd appreciate comments on this if anyone has one.

Another thought. This SHP block was designed as, well, Special High Performance as Dart says.

They have thicker walls for bigger displacment, there's some design elements that make it superior to basic 400 small blocks.

That being considered, wouldn't the current design elements outweigh the older design of the two piece seal?

I don't see this as being all that big of a deal.

I would not worry a bit.
The builder usually offsets the parting line of the seal aprox 1/4 inch, and puts a thin smear of rtv on the edges that butt together,.
2 PC seals worked for 30 years, and still do.

I did receive the check. I presume the converter arrived safely as well?
