Hey man, i love your vids. They are actually useful for most people who dont have a fortune to dump into a suped up crate motor. I have a 1970 chevelle and wanna do an LS swap what would you recommend? I hear a 5.3 with a 4L60E is a popular option. But which 5.3 from what year range? I hear to get one before they added all the VVT. Could you get this aluminum block and put the 799 heads on it? Or are they not compatible?
It all depends on your budget. The cheapest way to go is a 1999-2006 engine. Most newer year engines have DoD and/or VVT. But both can be deleted for around $600 in parts. 799 heads will bolt on any of the LS based engines, but may not always be the best option.
A 6.0L with a 4L80e is hard to beat for that budget range. Should be around 1-1.2k for a running 6.0L and another 1k for a good 4l80e. Nearly bulletproof combination and the truck would have a higher resale value then a 5.3L / 4L60e combo if you ever need to sell it.
They're fine, but the 2005+ LH6's come with 799 heads, which can be better. Really it depends on the application, turbo's don't care and 706 is fine if it's got a wuhan war whistle, but for a high reving N/A cammed engine the 799's flow better on the top end.
Forgot to mention: These are 24x reluctor engines which is why they use a P59/P01 PCM. 2005+ Trailblazer 5.3's are 58x and need the Gen 4 PCM's.
Great engines, have a few stashed @ work.
Right on
Great deal

Sweet!
I have a 69 C10 Chevrolet truck. All things considered what engine/transmission would you recommend with a $3500 ceiling. 6.0?

Do you know the RPO code on this engine? Or maybe what VIN engine code would indicate it's aluminum. Thanks
706 heads not ideal?

I wish they were that cheap here.
