Help me with dyno numbers Alright here's my set up. And before I go on, I really don't care about dyno numbers, I just want to make sure my set up isn't being hampered in some way and I will be hitting the track here soon to see how its actually running.
TSP Forged 347. 243 Heads with a 5 angle valve job and 2.05 Ferra intake valves with Patriot dual golds, 7.4 pushrods, stock rockers. SLP lid, LS6 intake, stock TB,MAF, water pump, a/c etc. Also had TR6 plugs(going to spray it soon), Pacesetter LT's, 3" mandrel bend Y with Flowmaster Merge. 3" I pipe with Spintech Prostreet and 3" over axle with 2.5" tailpipes. Cam is a custom with 238/242-605/610 on a 113+4. Yank SS4000 verter, FLT Level 4 4L60E and a stock 10 bolt with 3.73s.
I don't have the sheets, but it made 370 and 350 with the converter locked. It did show some signs of valve float around 6300ish, but power didn't fall off like a rock and carried out to 6600. Temp showed to be in the 80's with 33% humidity.
Back in Novemeber with a stock 98 intake and a 2.5" compression bent Y pipe and a cut out with a Yank SS3600 it made the same numbers. Now I know that it did pick up power considering its a lot warmer and I went to a 4K stall, but it just doesn't seem right.
I know a cut out is going to gain me a few more ponies as will new valve springs, but I was really thinking it'd be closer to 400 with the new Y pipe and intake. Any thoughts or insight what I should do or look at aside from the valve springs and reinstalling my cut out?
