You can also go with L92/LS3/LSA heads and a LS3 intake. Another "budget" option...

Whats that list cost to purchase......unassembled of course.

I'm going friggin nuts trying to figure out what to build....another N/A set-up, sc'er or single turbo set-up.

Building another N/A set-up is easy....you have to spend $15,000 to make 580 RWHP.

But I understand an FI set-up can be made up of much less expensive and much less "performing" type of parts. Its killing me to figure out what short block to build. I don't want to skimp out, but I also don't want to completely throw money at it that is a waste and won't get me any more power.

The problem is you can make that on just about any combination...especially if you are talking through a stick. Most aluminum blocks would be fine...especially the 2004-2005+ blocks and any iron block. Throw a set of rods and pistons in it with a stock set of heads and intake on it. Turbo would be the easiest to make power, centrifugal next. If you need to do it on pump fuel/meth/lower boost numbers you will need a good set of heads, intake, and cam.

The one component that will suck up a lot of your money is FUEL. To run 800rwhp out of a 370 and boost youre looking at a solid $1500 just in fuel parts. Especially if you consider not using "band aids" like a boost a pump or methanol.... then considering E85 or alternative fuels.

Between external pump, lines, fuel cooler, regulator, fittings, injectors, and rails I have easily over $2000 preparing for similar numbers.

Yea, my builder told me today about that.....he said no more than $1,500 should do it. Thats cool....

He recommended LS3 block, LS3 heads and intake. stock crank, forged rods and pistons. But if that iron 6.0 block is allot cheaper I'd go that route, no reason to spend any more than I have to.

You can't build this for cheaper with quality parts. It would work well for your goals of 800rwhp.

I have tons of other stuff to work with this:
1700hp fuel pump with pre/post filter (good for e85 to make 1000rwhp)
A/W intercooler
60mm Tial WG
Virginia Speed v3 turbo cam
and much much more

800rwhp for just the dyno run can be a cheap motor. A true 800rwhp street car using it alot should not be budget to last.

Hey....any issues with an iron block.....A/C "on" down here in hot *** south Florida.

Also, what the weight difference between a 6.0 aluminum and a 6.0 iron block.....?

.

LS6427

iTrader: (2)

I'd say 4,000 miles per year.......but I'd expect it to last for years at that mileage.

So besides a stock crank and forged piston and rods......what would make it that much better than using a 6.0 iron/aluminum block?

.

Iron blocks are about 90lbs heavier than aluminum.

LS6427

iTrader: (2)

I drive my car on the street only....I don't go ripping around like its a road race car on the street. I like to do highway pulls and hard accelerations.......

Will 90 pounds be noticeable to me?

And will it be hard to keep cool with say a single turbo? say 78mm.

So how much psi is the iron 6.0 and 317 heads good for.....?

seen this set up make 900 to the tire

The weight won't be substantial enough to notice it. Imagine a 90lb chick riding passenger, would you notice it?

Not hard to keep a turbo car cool with a good radiator/fan combo. I'm using an afco style 31" x 18" radiator (double pass). Haven't decided on fan yet, but probably a spal.

You can run enough psi to reach your goals without pushing water on 317s, so you don't have to worry about that.



I plan on pushing mine to 1100ish, same stuff except in a LS3 block with doweled mains, LSA heads, ARP everything, and a ported Vic Jr. A buddy of mine has pushed his LS2 block to about 1300whp without any issues.

my budget 347 took 800rwhp all day long. ls6 block, stock crank, forged scat h beams, forged mahle -4cc pistons, ARP rod bolts, LS9 gaskets.

Yes I would notice her if she was hot or had big ( . ) ( . )

I dont know why but on Vette we noticed the difference from the iron block the front got slammed but on F-body we wont notice it.

A Well built 370ci iron or aluminum block will easily reach 800rwhp I'm hoping my 347ci will do that.
