Will this block work fora motor build for my trans am i can get my hands on one from work for DIRT cheap right now other wise i could sell it again i supose
yes it will work if you use the block. The acc. and intake wont work at all. How does your motor mount on your car? I have not looked in a TA in a long time. I thought they mounted different than the 5.3. But why do you want to put a 5.3 in when you have a 5.7 in there now?

Well you can bore it out to 3.898 and have an iron block 5.7. but why?
2012 Cruze ECO M6 - Crystal Red- Just a little more boost than stock!
2001 Camaro SS - Rallye Red - In process.

yea you can bring a 5.3 to a 408. Basically it is the same block. Same as the 6.0 just different bore

4.8L and 5.3L have the same bore. 5.3L and 6.0L have the same stroke. They all have the same bearings.
Which 5.3L engine is it and what year? There are a ton of them. I'd aim for a 01-02 LM7.
Buy made in the United States. Otherwise your job might be next. Unless you already wear black shoes and a visor with golden arches on it to work in which case your fellow american has already failed you.
max bore on a 5.3 is 3.905. the stroke is 3.622 stock. i don't know what you mean by dirt cheap. but if you decide to go this route i have a 5.3 block, crank and main caps that is alreadt @ 3.905 that just spun a rod bearing, you could have for 75 bux, You are going to be replacing the crank, rods and pistons, anyhow. let me know.

ok i think i'm gana keep the motor and use it as a boost motor most of the guys on ls1tech say its a good budget build motor for boost so i'll have to get it out of my car soon and start cleaning any ideas on what i should put in it to make it boost ready?
as a shortblock to just toss in and have at it, it'll work great.
if you are trying to buy some forged pistons for it on the cheap, your best bet would have been a 6.0L since those 4" bore pistons are relatively cheap and alot easier to come by.
i got a pair of 6.0L heads if you need 'em. hahah 72cc chambers for the lower compression
