I'm Awesome
I've been eyeing the HT502 crate motor for my '99 Suburban... current 454 runs fine, but leaks a bit and has ~185k miles. Would love more juice under the hood and like the idea of a crate motor so that the truck doesn't have to be down for months during a rebuild.
I've done a fair amount of interweb research but haven't found anything definitive.... Is the HT502 a drop in replacement for the '96-'99 Vortec 7.4? Will the intake bolt up? Does the block and heads have all the sensor holes, etc? I would expect to have to do a few upgrades to the fuel system and PCM programming, exhaust, etc, but I would do these things with any engine swap. Not looking for anything more than what the HT502 is rated for. 500+ lbft would be awesome!
Let me know what y'all think. I'm not in a hurry... trying to do all the research to understand the pros and cons of each option before deciding anything.
