I'm in the middle of clearancing my LT1 for the 383 crank. I'm using 5.7 H-Beams (basically Eagles) The cam I'm going to use is a comp cams 224/224 568. I've done a search and couldn't find an answer to the question I'm about to ask.
Are there particular cylinders that will interfere more than others that I have to watch out for. I did read 2 and 7 were a problem for somebody but I don't know if that's for all. I want to get all of this done before balancing if i have to grind on a rod. Which leads me to a second question....What part of the rod interferes? and a third....Do I have to mock up the ENTIRE assembly to do this or just 2 at a time and is it possible to do it without the pistons.

Any help would be appreciated.

Thanks,

Bryan

 

Just mock up the entire bottom end. They cut the BLOCK not the rod where it needs cleared.

 

O.K., now I'm confused. I'm clearancing the block for the rod swing on the crank, but I thought there might be interference with the cam inside the block???!!!

Please clarify this for me. I don't want to do it twice. It's taking too much time and too much money as it is!!

Thanks,

I have been walking for 18 months... and spent 13K on my motor... trust me, I know what time and money is.

On my motor... I ran into block clearance problems on the bottom side... where the rods would not clear the block. I was also VERY CLOSE on piston to valve clearance. I did have to cut the rods a little for the cam also... however, my cam is a hell of a lot bigger then yours.

 

Thanks for the quick replies. I'll just keep doing what i've been doing.
