Now that I am done fighting with the FW in the Holley sniper, we have the Nostalgia Gold (old) Cup this Saturday, and hoping for a first outing with the Hemi Cuda....Almost ended up putting the carb back on it. But thanks to a helpful Dr. EFI, I was able to get it updated.

So last year at the end of the season, I ran the car, and it went a mid 6 with a broken valve spring and spun another bearing...This was after driving it all summer to all the cruise nights and such and working out the cooling system bugs. Plus the logger showed it dead lean for 0.5s off the hit.

So over the winter, we put the same rotating assembly in a new block, with all new bearings, and I coated the block with Glyptol, and added intake valve spring spray bars. We also put smaller restrictors in, and I am running an extra quart in the oil pan after checking the oil depth in it, and we removed the restrictive windage tray. Also went to a milder ramp on the cam which is now a lot tighter lash than the old school one we had, and lowered open spring pressure to #180 from #230, by changing valve springs....

All this for a better street/strip experience and longer engine life. I have another short block in the works as a spare.

The weather is not looking good for Saturday, so who knows at this point...But it is my 52nd birthday!
