6.0 lq4/lq9 shortblock will be the best bang for the buck. With the stock crank being good to approx 1,000 hp, and stock iron block is very strong.

only cons...weight

L92 headed monster would be fun for sure. Do a cam and valvetrain when money allows!

 

[OnyxSSS]

some extra costs might be:
good efi fuel system
motor mounts/plates
wiring harness/Programming


I have a motor and felt like it would take another $1k to get it in and running.

LS ftw

Carb it and don't worry about the wiring or EFI.

X2, also spend the money on arp hardware, including rod bolts

One of the car mags (Hot Rod or Car Craft, can't remember which) stuffed a turbo on a high miles junkyard 4.8 LS motor and made 1000hp with minor bolt ons. (Cam, intake, valvespring, etc.) They tried like hell to find the breaking point and couldn't achieve that goal. With that being said i'd just look at getting whatever fits within your budget and go from there.

I have an ls2 shortblock minus covers,cam and lifters

im thinkin a bone stock motor with a modded stock harness,200r4 trans that is built. how much should I expect to pay to have the ecm flashed or tuned?and what setting need to be changed to make it run?is there a better system to use this car is just a cruiser and I want to stay efi,im thinkin a gn fuel tank with in tank pump will do the trick for fuel supply?thanks for the input so far

Im stuffing an LS1 into my car with a carb and cam it should run well for under two grand. Good Luck

I don't think you need a GN tank, I believe you can get any g-body V6 tank.

not all g-bodys are fuel injected,gn tank has a baffel and is f/i

Aren't the 4.3 g-bodies TBI? Just trying to give you a cheaper alternative to a GN one.

not sure yet,what would you recomend

 

[1BADAIR]

if your gonna use stock rails look into the corvette fuel filter. the filter has the regulator and the return outlet built in
