This thread about if you can use a stock block and have success with a 4" crank and w-2 heads.

I have a bunch of high HP engines with stock 340/early 360 blocks, [basicly the same as a 340 casting], in service at this time. I have done them with the 4 bolt caps and my opinion it only adds to the cost of the finished project. Same with roller cams, No more power just a lot more money. In fact a couple times I have removed roller cams from customer engines and installed flat tappet cams and car has gone faster. Roller lifters fail and have ruined many a good bottom end. The only block failures I have experienced were due to other parts failing first.




well if removing the solid roller made the car go faster than the rest of the combo was not correct to begin with.
In a correct combo a solid roller WILL be faster. Oh and I have run many rollers including in a daily driven Vette and have never had a lifter failure.
