I am currently into my rebuild. Parts are as follows. SLP 402 High compression block, AFR 225cc heads, comp 238/240 .605/.608 cam, Fast 90/90, 36 lb injectors (may need bigger ?) , M6, 10 bolt with stock gearing. 2000 TransAm.
Mac mid length headers, y-pipe with cats, slowmaster exhaust. I am aware that the mac mid lengths and the slowmaster isn't the ideal setup for this combo lol.But it always gives me an excuse to spend more money later. I am probably going to put in a fidanza lightweight flywheel when putting everything back in. Also fuel pump in tank is upgraded and should be sufficient. Tune may be done by myself with ls1 edit. I have a WB o2 kit.
I'm thinking about 500 rwhp ? ANy ideas if thats close ? or what this comb. is capable of with a better LT exhause and higher flowing muffler ? If I decide to get it tuned by a pro any suggestions of a good tuner in or near CT ?
Thanks

P.S I don't have the CR numbers on me now but the heads were milled by AFR to around 66 cc I believe, abd the head gasket i believe is .040.
Thanks

I would guess 480-500rwhp. I don't want to get your hopes up because I know how it feels when the dyno kills your confidence.

Yeah I know what you mean. I see a lot of people saying on this board that they have low numbers, when I look at there setup and it seems normal too me. I'm sure it must be depressing, I hope I don't wind up feeling the same way

Anyone else have any idea's ?

I would do the headers and exhaust before you dyno. You have all these great parts for your setup except the proper simple boltons.

Well, as I said I do have headers and cat back done but it's with mac mid length headers and flowmaster exhaust. I am aware that some kooks or another type longtube would be better and I have heard that the flowmaster does not flow that well compared to other options out there. Regarding the headers I wanna get LT's that arent too low to the ground as I would like to lower the car about 1 - 1 1/2 inches.
Thanks

The headers wont hurt you as much as you think. Ive seen 427 LS1 cars put down 565HP to the wheels with macs. I say you have an easy 500.

You'll be close given the fact it's an M6 on a 10 bolt.
