427 Solid roller numbers We strapped it down tonight.. I don't have a sheet it got too late so I will get one tomorrow. Final numbers were 560/515 I was a little dissapointed at first but realize we are going thru a 9 inch and we had great mid range power/tq. If I remember correctly it was around 450ish at 3500 and carried all the way to 5500. Car pulled to about 6500 and started to level off not nose dive. We pulled it to 7300 but think the Fast isn't quite capable of keeping up. Car feels alot faster than the other setup that had 557 at the wheels thru a 10 bolt?? I have heard though that a 9inch will rob alot of hp?? I will post a sheet asap and get the video in a day or two. Thanks guys.

Who tune the car. What if vengeace tuned it what do you think the power would be? But that is low for you set up I would say closer to 600 not 560 maybe if you had a dana s60. But nice bro congrads. Got any vids

^^^That is what I heard 25-30 so figure 575-580 at the wheels thru a 10 bolt with 17's on the rear?? That dyno is not an easy dyno to get a gravy number either. I remember when LG used it and almost swapped motors in thier race car cause it showed 10 less then everything else the were used to. Found out it was the dyno??
But what ever you have a sick car now and that all that matter.

I am not going to argue with you. Do a search and you will find the facts on the 9inch
vs s60 threads. Appreciate the comments either way.

Would opening the inlet up to 100mm and putting a 100 mm tb on there help at all ??
I only ask because my 402 has a ported fast 92 from Ron at Vengeance and due to my 95mm tb issues, the tune was done with an ls2 90 mm tb. After the 95mm tb was modded to work a swap was done and 6.x rwhp and 16.8 rwtq was gained at peak. Also 20/20 was gained under the curve +/- 1 or 2. I'll post a link to the graph for ya.

Heres the link showing 402 with 90 mm tb and then the improvements are with the 95mm tb. Your motor may benefit even more then mine.

Nice numbers man, do you plan to hit the track now that you have a rear end to handle the power?
You couldn't have picked a better tuner, we are lucky to have him and Alvin so close to us.

12.5:1 and solid roller and only 560? Dont get me wrong, 560 is stout, but I was just expecting more. My 12.5:1 403 made 561/503 through a 4.11 geared 9in with a hydraulic 243/251.
Sick car regardless man, i'd like to see the graph
