I think A&A sells a forged 346 short block for $3500. $3500-3800 for a forged 346 with a stock crank seems the norm. For $4500 you can get a forged 402...
Also is that installed or just motor?

. So is this a fair price or am I being taken for !!!You really can't compare the above to one of the bargain basement pile of garbage motors that are sometimes advertised here. The cost between an average motor and a great motor really isn't all that significant.. Do it right the first time. Just my .02.

Different strokes for different folks. Yes, you can get a bargain engine. And yes, you can buy an expensive one. A bargain engine may work just as well as an expensive one for you. Or it may be more likely to fail (even if it never actually does).
The only thing I can say is know what components are going into the motors and do an apples to apples comparison. They are not all built equal! And even if the components are the exact same, assembly is crucial. Go for a reputable company who has done a lot of motors in the power range you are looking to make. For me, the decision was simple... once I knew that I had to be able to break into 800rwhp whenever I wanted to with a boost controller, I gave ECS a call. They have plenty of 700-800rwhp cars out there which proves that the components they use AND their assembly (IMPORTANT!) works.

I have been very happy with my forged A&A setup and I believe Chriswtx pretty much hit the price range and I have had mine in for 4600 trouble free miles and if the LS2 402 was perfected a year ago I would have went that route, however there is nothing wrong with a 346 if you want to stay with the stock cubes

I know of 3 people that are "Currently" having to have their motors re-ring'd after about 1500 miles because one of our "west coast" tuners cant seem to keep them from blowing oil all over the place.
Actually, I think Norris Motorsports in FL is having to fix one of them as I type this. Its amazing. That motor only lasted about 2000 miles. Unfortunately it was blowing oil all over the place since day one...
Look into the shops that really take their time building the motors. Also, dont use "Budget" parts. Cause you will definately get what you pay for..

Exactly. You want a builder who does everything in house. The builder that I think Jeff is mentioning has used a number of different machine shops over the years. While that may be fine for some, it's just not for me. I also wouldn't mail order a motor unless absolutely necessary.
As for the LS2 402 - I think it's very overrated for a FI app. There are much better options out there.

And what options are better, seems ECS is pumping out lots of mid 800's or more with this motor and blower setup, Canjundude has his LS2 rocking with the STS setup and American HP is doing his LS2 with the KB what gives here

I'm not suggesting that good power can't be made with an LS2 402, just saying I don't think it's the best option. I'd prefer an all-bore approach. Either a 364, 378, or 388 would be my preference.
I’m discounting race setups here as those motors get refreshed every season or two.
What did Cajun's car trap at the strip? How many miles on it?
Like I said - I'm not saying there aren't some great LS2 powered cars, I just don't think they've proven the test of time at all and I wouldn't want a relocated knock sensor (relocated to a position where it is less effective as I understand).
Plus the strokers don’t seem to fair nearly as well as all-bores when it comes to longevity.
Just my .02.

. So is this a fair price or am i being taken for !!!You can spend anywhere from $2,700-$4,600 for a forged shortblock. There's value in having a Lingenfelter motor, but they use stock rods.
C5s will continue to lose value fast, so if you're considering swapping for a C6, you might want to consider an LS2 motor as a longer term investment.
Beware shopping by the cheapest vendor. I bought one from someone who didn't know what they were talking about, and was burned big time. I lit up $5,000 in cash a year ago and the car hasn't run since. Also use a vendor within driving distance. Mail order motors in general aren't worth the savings, and vendors are more likely to take care of you in person than over the phone.

Yes, Guss with his 402 runs 11.1@129mph on motor and with the NOS he has run a best of 10.7@136

$ 100 Head Gasket set
$ 100 Oil, Coolant, etc
$1,500 R&R

$5,000 Sub Total
$ 285 8% tax on hardware

So $4,500 isn't bad.
