Re: 400 Engine Build (phxraptor)
I thought the price of a Vette servo was more than it actually is.
Here is a little info on the servo upgrade. A Google search should provide many more links to information than this one alone does.

Re: 400 Engine Build (phxraptor)
There's a four bolt on EBay now. Don't if you want to stick with the 2 bolt. Hopefully this won't lead into a 2 bolt vs. 4 bolt battle...

I had a 400 in my last vette and it was fantastic. To me, they are a great blend of performance and streetability. The advantage of displacement I guess. I'm in the process of putting a 400 in my current vette.
Good luck with your project!

Hey guys, don't you just love spending other people's money? :lol:
Dean, here's another 4 bolt on E-Bay, it's in Az:

A factory 4 bolt will be just fine if you don't run 500+ HP or beat it to death
:cheers:

Re: 400 Engine Build (Caboboy)
:confused: I thought the 4bolts were prone to overheating causing cracked cylinder walls? Don't forget I live in Arizona,115/118 degrees in the summer(But it's a DRY HEAT) :lolg:

Re: 400 Engine Build (phxraptor)
I've never heard that :confused: Maybe someone else could chime in.
What you do hear is that factory 4 bolts have weaker webs because of the extra holes, but I don't think that's an issue for a motor that isn't beat on. If I didn't have the nitrous, I would've done a 4 bolt, I just figured I'd be better off splaying the 2 bolt. :cheers:
Good luck!

Re: 400 Engine Build (phxraptor)
Contrary to popular belief, I think you'd be fine. There was quite a discussion here on that subject about a year ago, and most of the more experienced 400 block guys seemed to agree a 4 bolt would be OK under these circumstances.
But, that being said, if you intend to run that kind of power and don't have the block yet, I'd go 2 bolt splayed. Better to be safe than sorry IMHO..... But, keep in mind this is my first (and probably only) 400 block venture :cheers:

Re: 400 Engine Build (phxraptor)
A stock 4 bolt may stand up to moderate power increases. The 2 bolt block, stock, is stronger than a stock 4 bolt. The weakness, isn't because of the material removed in the drilling for the extra holes. The castings are thinner and weaker to begin with. The siamesed cylinder walls, overheating questions, and the drilling of steam holes, are discussions of 4.125" bore 400 blocks, independent of the 2 vs 4 bolt situation. If the price and availability of a 4 bolt is right, and you deem it suitable for your application, go for it. Just be aware that it is LESS desirable than the 2 bolt. Don't be talked into paying a priemium for an inferior 4 bolt block. Too many people are unaware of the 4 bolt's weakness, including some sellers. Those people, falsely, place a premium on the 4 bolt. Caveat emptor! Good luck, and...
