Building a new motor to swap into my 89 GTA. I was thinking about building a v6 turbo but that may prove to more of a challenge than I first thought so without further adue..

Dart Little M, Iron Eagle

vs

World Products Motown

I was also going to go with 400 mains... does anyone here run a similar setup who could tell me how hot it runs? I have heard the 400's run hot, but this is an aftermarket block and I believe both claim to run cooler than a GM block. This is going to be a supremely tough engine that will probably see 800+ hp depending on which camshaft i use . I really want to pick a very sound block for obvious reasons and these are the only two manufacturers I can find any real info on. Any input is appreciated .

 

go with the dart little m block.

 

Any thoughts behind this choice?

 

Their are several people on this board running this block search the archives for more info. I plan on using the dart little m block on my next buildup it's a solid foundation for real power and dart has an incredible reputation but it's your choice these sites should help.
