taylormac1993 Posted January 9, 2017 Share Posted January 9, 2017 I was just wondering if anyone has built a motor using the 255 shortblock and 25D heads. Seems like it would be pretty easy as all the blocks are virtually the same. I just want to build a stock motor that will run right NA but be able to handle low boost numbers reliably if I decide to go that route in the future. Are there any shortcomings that the 25D heads have when it comes to boost? Also wondering if it will bolt straight up to the stock 5MT trans (clutch, flywheel, slave cylinder differences?) Just tossing ideas around right now and I didnt find anything concrete online. Link to comment Share on other sites More sharing options...
