Hey guys, first post here. I'm around the other fe forum, and look in here some, but never posted here before. I'm in the stages of selling my 514 and building a 427 stroker for my drag car. I'm keeping the dry sump setup from the other motor and using it on the 427. I'm going to have Blair hopefully help on the top end of the motor, if not more, depending how my cash flow is.
Is there anything special I should know about hooking a dry sump up to an fe? I know if I have Blair do all the work he'd know, but like I said, not sure how this is all going to come together yet.
My plan is using a freeze repaired marine block I'm getting from hotrod. It's got a weld repair in the valley on each side. I'm not worried about the work, he does a great job fixing these things. I'm more wondering how much power a stock block can take. Sonic tested with thick cylinders yet at .060 over now and one sleeve.
I could have asked all this to Blair I'm sure, I left a message but didn't get ahold of him yet and when I do I don't need to tie up all his time.
Thanks guys, Darin

Nothing really special about running a dry sump on an FE. Aviaid makes a lot of FE-specific dry sump parts, you might want to look at their web site.
On the block, if you are planning to go over 700 HP I'd fill it if it's .060" over. I have a .060" over 427 sideoiler that has hundreds of dyno pulls at around 650 HP, without fill, so I know they'll take that at least. But I think I'd be leery of going over 700 without at least a half fill of hard block. JMO - Jay

Thanks Jay. I looked at their site a few days ago and I'll be after a pan and a couple other things there. I'm thinking about 750 or so horsepower, and it will be filled to the water pump holes.

I think with it filled you should be good for well over 800 HP. Good luck with the project!

Thanks again Jay! If my wallet allows, it may be over 800. I've wanted a 427 since Dad blew his up 30 years ago, it should be a fun project.

You'll find the most difficult issues are getting all the necessary brackets and mandrels to run accessories. I've done several dry sump engines and the easiest part is getting the pan and bolting it on....hahaha
Before you buy the pump and brackets, you'll need to map out how many stages you want on the pump. If you are going to have the pump pull vacuum on the crankcase, it will need an extra stage for that, along with the associated plumbing. Also, if you plan to run any accessories other than the alternator, you will need to know for when you buy the mandrel, spacers, etc.
If you go with Aviaid, have your game plan mapped out and I would suggest buying everything that you need from the same company. Dry sump stuff is cool....definitely not cheap, but definitely cool.

Brent, I've got the dry sump setup off of my 514. I'm selling that motor, but keeping the dry sump. I think all I need to do is some bracket modifying and a pan purchase. Probably have to make a few new lines, we'll see. I have no accessories to run, water pump has an electric motor, no alternator. I just run a belt for the pump on a crank pulley.

Aviad makes a balancer spacer with a built in HTD drive you can use. Makes it pretty simple to put the belt right behind the balancer.
Sell that pump and just buy a complete Dailey set up. You won't be disappointed in the quality.
