I would like to see anyone running 17's on the front and 15's out back. Trying to figure out if 15's or 17's would look better. Thinking of going with weld RTS.
You definitely know your stuff. And you're right they are all 2550153. What's weird is 2 of the blocks are clearly different. They have different castings and are lacking the 2 side bolts going into the main caps. Yet they are all the same number on the block.
Got a pretty sweet stage 2 book too. Has all the engine tolerances, part numbers, casting numbers, break in procedure, etc etc. Would be cool to scan all of it for people to see.
Story is: got an 87 GN. Want it to go fast. Was exploring options. Ran across the stage 2 motor for a good price. Asked on here about them. Seemed to be a good fit for my build. Went down to pick it up. He had a whole bunch more and he didn't need them so he gave me a good price and I cleaned...
Idk I have to pick it up still it's a few states away. Supposed to be a fresh motor. I'm going to go through it tho. Probably have to lower the compression quite a bit and use some more sane spring pressures and cam for lower rpms. Nascar motors weren't exactly built for longevity. Here's a pic...
