i'm saving to build a 393 for my notch i was wondering if anyone has experiencewith this blockor knows if this a quality block? also should i go siamese or non siamese? http://www.latemodelrestoration.com/...1&comp=LRS

the reason for going with such a strong block is eventually it will be a turbo motor, and someday i hope it will go into a cobra kit car so i want a motor that will last a long time at decent power levels, and can handle a couple rebuilds if necessary

thanks in advance

um i do not have experiance with this block or any....but from what i have read on the page that sounds like a pretty damn good block to build off of, but dont take my word for it wait till someone else chims in. but good luck on your build man

but im not sure about the whole NOTE: Siamese blocks are solid casting between the cylinder bores. There are no water passages between them.This is done to increase the strength of the block. thing because wouldnt this cause the engine to over heat quickly?

thats one of the things i was wondering, it will be primarily a strret motor so it needs to cool properly

ya i was thinking about righting that block down as a possible block for my build...but then i saw that and it made me question whether or not this is a race block, What are your expectations for the engine cause if you get a 94+ block they accept roller cams, and if preped properly/tuned can handle something like 700hp.

they do sell that block in a non siamese bore just so you know

Yes you can buy that block in a non-siamese bore. However having ran the siamese bore block for a number of years I can testify that I have never overheated a motor.

BTW if you are going to go through the trouble of building a 393 why would you not jump up to the 408?

iwould like a motor capable of decent engine speed, i know a turbo is gonna make the motor wanna keeprevving, andusually more stroke=less rpm....but keep in mind i'm not completly sure what these blocks can handle. Is your 408a turbo motor or n/a?

You might want to check on the price of a DART block. It comes already machined whereas the Ford Racng ones don't. You have alot of machine work to do to get it ready to use.

i didnt know dartblocks were already machined i'm happy you told me, the price will probably even out but the dart block is stronger
