Just looking to see if anyone knows if you can buy assembled blocks already built, balanced and the whole works good for 800-1000 hp for a 91 7mgte. Just curious if there is and what the overall cost difference is compared to tearing one down and building it yourself. also considering time, if you can just order one and build it from there compared the amount of time it takes to do it yourself. Ive built one before a few years back that without being tuned netted almost 790 rwhp. Im looking to save some time on this one if i can find one with the right components and done right.
