99 Trans AM, LS1 or LQ or?
Hi Guys!
Absolutely new to this forum thing so if I screw up like post this when I shouldn't have or wrong forum etc please be kind?
Here is my dilemma, Not too long ago I purchased a 99 Trans Am, LS1, A4, Flowmaster exhaust because of a wild hair. Several weeks later I noticed a knock coming from the bottom end. I was crushed... After watching many youtube videos and the help in these forums, I pulled the engine tranny etc from the car. While dismantling everything I noticed that one of the bolts from the torque converter to flywheel was loose. I just shook that off. I tore down the engine to bare block. I could not find a spun rod or any bad bearing etc!!! Then I looked up the sounds that a loose bolt on a torque converter would make and.... OH GOD! So apparently I went thru all this process over a loose converter bolt.
So... Since the engine is all tore down, Shall I build a stroker 383 out of it? Or go with an LQ block and stroker 408? I want a bad-*** street ride that I only drive on the weekend or when the weather is good. Probably wont take it on very many long distance trips. Maybe see a dyno or drag strip once in a great while. I'm kinda wanting something with at least 500rwhp N/A and be able to beat my friends 2015 Mustang GT500.
Any Comments or questions or ?
Thanks guys, will be glad to hear some great expert opinions!!!

I wouldn't say I'm an expert but if you have the engine out most guys on here would say, depending on your budget, more cubes the better.
If 500whp is your goal a stroker 408 is probably going to be your best bet with the right top end.

Thank you so much Masochist, for a while I figured no one wanted to bother with this thread.
So I was thinking
pump gas, N/A
408 lq with flat top 3cc pistons (forged crank, rods, pistons)
slp lid
Ls3 intake manifold with stock 41lb injectors
CNC ported ls3 heads 68cc (will this make about 11:1 compression?)
rockers? IDK
upgraded springs to handle a larger cam (springs to get idk?)
cam? IDK
Rebuild 4l60e with trans go kit and all the bells and whistles rated 650-700hp
Ceramic coated pacesetter headers (1 7/8 or 1 3/4?)
qtp y cutout after headers
x pipe to dual exhaust to the quietest non restrictive mufflers I can find
Want a weekend warrior that the girlfriend can drive if ya know what I mean.
