The dyno figures were to high for me to accept as realistic.It was showing 427hp at just 4100rpm and peaked somewhat over 600hp at 5900rpm on an unlocked converter.The truck would spin the tires on the dyno rollers at almost any speed in 1st or 2nd gears.Like I say I'm going to dyno again later,there's no way those figures are realistic.

 

Either way, it sounds like that thing is making some killer power. How does it drive just cruising at part throttle? Ive noticed that as I mod it seems to make the throttle response "jumpier" and it really isnt as comfortable as I would like it to be. Im sure part of that is the need for new rear shocks. Are you doing your own tuning?

 

I'm having some problems with the 90mm FAST throttlebody not allowing the engine to return to idle,the technition at FAST says he can cure the problem next week.And you have to be very carefull because just a little to much throttle will send you sideways,not cool in traffic.

 

that has to suck. i mean, it's cool to be able to do that, but for it to do that when you don't want it to. i hate it when my tires spin when i dont' want them too. i can't imagine touching the pedal and the *** end getting sideways.

 

Yeah,leaving the office today Jim TnTk53 said when I punched it at 20mph that it was hazing the tires with smoke coming off the tires all the way through 2nd gear.It didn't just sit and spin but it was hard to keep straight.

 

whitt, if you can, why dont' you try and make it down to greenville this saturday. i hear you can make some money off the diesel guys.... btw, i would love to see that beast in action.

 

If you are still running those 17 inch Centerlines, couldnt you get a set of 315 drag radials? It wouldnt cure your prob, but may help it quite a bit. That would be scary in the rain. I dont like driving my truck in the rain, since it gets no traction what so ever.
BTW did you do the tuning or someone else?

 

I can't make it saturday my daughter is home for springbreak from college.But I will make it to at least one of you guys race weekends,after I get the truck sorted out.I'd really like to go to Hattesburg when a bunch of trucks are running.

 

Can you you give me the details on your set up, it sounds awesome. Like your heads and compression and any other info. I just got the LS2 402 shortblock and AFR 205's for my 70 C/10. A magnacharger is also going on top of it. Thanks in advance

 

I'm running a Keith Craft 403 shortblock with a ported LS6 oil pump and a Comp 228/234 .588/.598 115+5 cam with Comp R lifters.TEA stage 1.5 6.0 o-ringed heads with Comp 978 dual valvesprings and titanium retainers.Comp 1.75 Pro Magnum rockers,NPG coolant with the high capacity waterpump plus dual Flex-a-Lite fans.A Radix Magnacharger with a 3" pulley and a 90mm FAST throttlebody on a ported Magnacharger intake tube with a modified airbox with ramair and a UPD lid.That's most everything
