Input on an N/A combo
Input on an N/A combo So I am basically chasing my old Vette. I had an LS2/A6 with LS3 top end and an LPE GT-11 cam. That car made 437 rwhp and ran a best of an 11.002. I built it as a grudge car and now I am pretty done with that aspect of racing.
I know have a bone stock 2000 Trans Am A4 and it's pretty much a blank canvas. I'm looking for input on how to get down to a low 11, high 10 N/A. I want to retain all the creature comforts but don't mind adding some light weight suspension parts or a Fab 9' to keep weight in check. I also don't mind a big cam and high stall.
Can I do this with the stock bottom end? Ported 799's or after market castings? Am I better off looking for an LS2 bottom end to do an LS3 top end on?

If you prefer the LS3 top end, then you'll need a 6.0 block. Can't really say as to which is cheaper, as I don't know what all you currently have. I just assume you don't have a 6.0 short block sitting around, but could be wrong. If you do, then that's the route I'd go.
I will spend the money if needed. I have a set of unported 799 heads I'm either selling or will send out to get ported depending on which way I go. I am no opposed to a good set of after market heads. I also am planning on a FAST 92. I don't have a 6 liter yet. I would rather use what I have. I wasn't aware that LS1's are getting to where I want to be pretty easily. I have actually never had an LS1. All my LS' have been 6 liter or larger so this is a new territory for me. That's awesome that I should be able to reach my goal with a 346.
BTW, I love you car man. Mine is silver and I plan on running a set of 17/15 dark stars too.

Getting between 440 and 450 rwhp won't be too hard with a set of nice ported heads, a FAST 92/92 combo, and a decent sized cam; something in the high 220's/low 230's intake and low to mid 230's on the exhaust side. I guess the biggest thing for you right now is deciding if you should have the 799's ported, or sell them and buy a set of aftermarket castings. Another option for you could be the Trick Flow 220's. You could get them through Brian Tooley and have him do his hand blending/port work on them. Brian stated that his hand worked Trick Flow 220's are equal, if not better, than the Trick Flow CNC'd 215cc heads.
Yeah, I agree. An M6 will always dyno higher, but if you're goal is to run low 11's, as long as the power is there, which it will be, and the suspension is setup good, it will run great times.

Here is a link to our TEA/Tick H/C package we offer. I feel it is very comprehensive and won't leave you searching or looking for little knick knack parts like gaskets and bolts that will be needed during your H/C swap.

We also offer FTI and PTC stall converters and can match the perfect stall to your H/C combination as well.
I don't see any reason why a well matched H/C and converter combination with good suspension and track tuning can't go 10's.

Anything MAST puts its name on is nothing but great. Just make sure if you get those heads, don't go buying some off the shelf cam. Get a custom cam made for the LS3 style heads.
I have had experience with LS3 heads before but I never thought of getting a set of small bores. The price difference isn't so far away when you factor in using a stock LS3 intake, rails and injectors.
Yep, being able to run the stock LS3 intake and rails is a huge plus. No need for a FAST, ss the LS3 intake is really good.
