Building an engine can be an extremely complicated affair, given that you are trying to piece together so many different parts that all have to work together. Thankfully the folks at PBM are doing the hard work for you by putting together full engine kits in several configurations. Each kit contains everything you need to assemble your next powerplant from the hard parts like cylinder heads and pistons all the way down to the fasteners that hold the engine together. Kits vary as some include a block like the Big-Block Chevy 632ci Street/Strip, while the more basic 383ci small-block Chevy kits do not. The Motown LS 427ci and small-block Fords from 363 to 454ci also made the growing list of kits.
