To my knowledge (does not mean I think I am right) the problem doesn't come from water volume. I think that if you didn't have the holes between them cylinders the water would make a hot spot and turn to steam. It would trap the water and just keep heating it. The holes prevent steam because it lets the water flow. I could be wrong though......unsure....??
I guess if money was no object I'd have a couple of them 1750-2300 dollar blocks. Hell I'll even take donations from you.Quote:

I quit reading when 75TA said he was pulling a 383 to use a 421 and is overlooking the 377 build. OH MY GOD, I thought all these 'rock throwers' knew thats the only logical thing to do with a 400 block. Well,,,,,,,there is this road on Pikes peak that has a very narrow curve and I just think a 400 would look so lovely going,,," help I'm going to starve to death before I hit the bottom ".:LOL:

A 377 has no place in a street mobile. That engine don't make power till about 4000 rpm. Unless you want to run a big stall or a manual and a deep gear is a must. I like torque and long strokes equal long torque numbers. Cubes is where it at on the street.
cause i had 1 and i cant change my name and i never thought i'd own a 406. 400 block if u will but u know now that i have ran 1 i will never go back ok. everthing i say is JIMHO. Steve Morris helped me with the combo and put the rotating assembly together degreed the cam and i did hte top end cause i just gotta have my hands in it. I am set in my ways u are set into yours and lets agree to disagree and no donations from me either. and my next motor will be a 406 and the 1 after and the 1 after that and the 1 after that and the 1 after that and the 1 after that:DQuote:

This thread has turned in to a fricking joke! :(
Most of the Gen I small block blocks GM is producing nowadays are of a 400 bore (4.125" or greater), some do have 400 mains, and most have siamesed bores, just like the 400. Heck, even the new LS2 and LS7 motors have siamesed bores. There is nothing wrong with cylinders that touch.Quote:

If you will notice I am cracking the blocks.Well over 650 h.p. maybe in a drag car for 6 seconds in the 1/8 or maybe a 10 second 1/4 mile pass but never in a circle track car lap after lap.You might get 10 -20 nights out of one if you are very lucky.Better say you hail Mary's if you are really making these h.p. numbers.
