R07 Engine: The Ultimate Racing Design (Current Generation)

but this these are drilled in between uh and then this is actually pulling water out here to keep it flowing between the two exhaust valves there's the the 184 bow tie block on 18 degree heads it's at the same block that the sb2 started on or did they come with the roller like one of the roller cams in the offset lifters and everything become the standard if you could steal both the SP2 head on a conventional like a 184 bowtie block so but it takes a special camp so quickly evolved into SP2 having its own block staggered lifters that more fits the cylinder head configuration because you could take an sb2 head and bolt it onto a standard small block Chevy block if you wanted to use a special camshaft and lifters that means you could take a NASCAR cup series head from early 2007 and bolt it onto the block from a Chevy K 1500 pickup truck with a 350 for that means the old small block Chevy architecture lasted longer in NASCAR than it did on the on the street because by then the LS engine had already been around for almost 10 years so you know maybe these engines were actually more stock car than you thought they were for longer than you did think they were well maybe you didn't I don't know is this news to you like speak up in the comments is that surprising but you if you want to look at bother them too this is is this like the evolved yeah SP2 block because it's got the um these on here I've heard stories about these or can you explain what this does well this brings the water if you can see the water normally comes into the front of the block on a small block Chevy but you're again with the Siamese Sports hottest Parts in the center so bringing the water into the center of the block instead of the front does that help with overheating it did obvious visual differences going on here this looks like a middle ground between a standard small block and r07 block right yeah [Music] yeah you can see the staggered lifter boards and the the original 184 bowtie blocks did not have this scavenge Port built into them did they they did it they did some regular Chevrolet does not have that in fact we uh we would drill you know and tap this ourselves did you have to rebuild those after every race we did in that era Daytona when you're down there for 10 or days or more and all the practice qualifying in the 125s pretty common
