Hello guys i've been looking around this forum for months now and finally decided to join. I recently bought an 06 Chevy Silverado 1500 4.8L 2WD to turn into a pre-runner it's something i've been wanting to do for a couple years now and finally saved up for. Instead of just grabbing 6.0L LQ9 and dropping it into my truck i've decided that I want to go ahead do a full engine build.
Would you guys reccommend starting with a cast iron engine block or an aluminum block? It will be in a truck so I was going to go with a cast iron from Summit. Once I put a long travel kit on the truck I don't think the weight will significantly affect performance. I'm looking to push 500+ HP with this build.
Here's the block I was considering.. https://www.summitracing.com/parts/nal-12609999
Any feedback would be greatly appreciated, I've been doing a lot of research but most of the threads I find are about these builds for cars not trucks. It won't be strictly for off-road it'll also be driven around the city too. Any input or reccommendations are welcome and appreciated. Figured I would start off with this question before I get into anything else, feel free to recommend anything (pistons, cam, heads) you don't have to get too in depth but it would be nice to know why you recommend the block you do and for whatever reasons.
Thanks guys I hope to hear back from some you.
