I am having issue here with what motor to get for my 99 trans am m6 .I was gonna buy a AES 390 and use a novi2200 on it . Now I see lots of people using 4.8 5.3 motors and they are stock . So I did some looken and found a place where I can buy 4.8 5.3 and 6.0 for like 3200 new the hole motor . So I was thinking of doning one of these and save 5 grand . What would u all do buy the 390 and call it a day or go with the cheaper motor . I have 15 grand to spend if this helps but would like not to sppen it all .lol

most buys would rather buy a used 5.3 than a new one for these turbo builds cause if they hurt the motor it is cheap to replace.


I personally wouldn't spend 3200 on a new 5.3 for a FI build


What are your goals for the car anyway. power level street or track?

Also I had close to $2500 in 1 347 short block and 2800 in my second before going with my AES 385. I would much rather run a forged stock cube ls1 than a stock 5.3

The car will be street and track . I was hoping for 650 at the wheel .

I would spend my money on either the 390 or build a forged 347

Don't go buy a new 5.3. People buy the used ones because they are super cheap.if you only want 650 wheel, then a super expensive short block really isn't necessary. A stock crank with good rods and pistons will be more than enough.

Exactly. I made 676 rwhp with my first 347 with 241 heads and a D1 at 13psi on 93 and Meth

We can get you in a turbo short block good to 700HP on sale now for $1799 with a 90 day warranty or good to 800hp with a 1 YEAR warranty for $2499. These are very budget friendly options that can take a huge beating. Let us know if we can help you with the build in any way.

I was gonna do 9.5-1 and mild cam and of 16psi and hope that I hit my number if I don't I don't , if I do I would be happy . I am sure I will make more than 650 . It is what it is.
