My SC 6.2L has more power then a NA 7.0L but man iv been thinking I would love to have a 427ci Silverado. I wounder what a 10,000 mile TVS1900 6.2l would sell for. I know a new GM 7.0L would cost $14k. I wounder what kind of mileage I would see with a stock 7.0L. This is a DD ya know.

 

I like my 427 Sierra it makes decent gas mileage when your cruising i guess about 17-18 hwy and about 12-15 city. Of coarse mine is setup entirely for boost but a NA purpose built 427 will outrun a supercharged 6.2 I would think. Mine on motor outruns new 6 speed bolt on 5.3s with nitrous fairly easy.

 

Im thinking just a GM create 505hp 470ftbls 7.0l my 6.2l is running way more then that but hp isnt the goal im going for. its just a dd. im getting 18mpg if i keep it just below 60mph. dont know what id get hiway yet. running just under stock VVT. I think id be happy with a 7.0l with my headers. even tho there a little small for a 7.0l.

 

how much would a used sc 6.2l be worth. no were near a new 7.0l i bet

 

Nope...

 

ill have to pray to the gods of fuel and fire for a LS7

 

I would stick with what you have, but hey it's your truck.

 

Take a trip to Lockport and drop that tvs off at my place, then I'll pray for ya too.

 

Think of a price think about it and PM a price I'd take it off your hands

 

havent thought on a 6.2 to 7.0 stroker? 429ci i wonder how that would do up against a ls7
