That would be a pretty non streetable cam to pick up that much rwhp on can alone swap.

Lingenfelter had a H&C package for the LS7 that was pretty good, but on the quite aggressive, not so mild side that legitimately put the LS7 in this power range. The package plus and LS7 is also well above my target price here.

and because you didn't say anything about weight you can always go with an LQ9 block (iron truck block)

Basic prices

Block 1000 - 1500
forged internals 1000 - 1500
heads 1500 - 2000
Cam 150 - 300
Dry Sump 2000 - 4500

If we leave is NA we could get 550 to 600 no problem the last 50 might be a little harder and still make it nice on the road

I would say skip the dry sump and get a TVS 2300 its still under 10K and we can go over 650
1000-1500 for a stock block? You can get a dart block for that coin

My point wasnt the cam, my point was how much power is corked up in that engine. Leave everything stock and add a snail or hair drier and you've got your power and then some. I only mentioned a valve change cause for whatever reason chevy made that baddass motor and put 2 piece valves in it.

The entry point for Dart's most basic block is $1,500 and goes up fast. That's just the block.

I understand, i built a badass dart blocked 347 if you forgot. Going by Johns price points i would never pay that for a stock block

Vettezuki 06-13-2012 03:02 PM
Maybe he meant short block and not bare block? :huh:

blackax 06-13-2012 03:16 PM
I've never had to buy a block thank goodness, but I cant find a new ls3 block for much less

blackax 06-13-2012 03:24 PM
It also looks like the dart blocks are gen1 blocks
