Well Dave that would be 386.00 to be exact. The springs and retainers were free courtesy of PAC Racing Springs. :-P

Okay, WORTH more than most of my engine. The 6.0 and LSA heads cost $1500.

^^^^ This.  :cheers:  But my motor still turns 9200+ rpm

wow
I was hoping to make 7500 before launcing parts, but I bet the rev limiter on this tune is 6500. I really have no idea yet.

Dave is running a Dart Buick headed dry sump small block BUILT to spin
that high. You can certainly spin a stock LS to 7,500 but you WILL break
stuff.

Our rev limiter is set @ 6,700, my shift light is at 6,200. With a RR4 Jerico
(clutchless shifting) I generally see 6,500 on the recall after a run. We made
peak power right around 6,500 with an intercooled S488 on VP C16 gas. You
don't need a giant cam when you go turbo, I think we run something in the
240's I & E with .650 lift.

Lukes cam is cute...  You really need GREAT springs, Oversized Pushrods, and Shaft rockers if you want to live over 7200 for long periods.  Drag racers got it easy.  WOT for 24 seconds at high rpm is bad for parts.

jesus man, buy some push rods.  One solid ding on the rev limiter and they're bent, you won't even know it until it breaks.  They're dirt cheap.

I just knocked the exhaust off on a speed bump during a leg stretching shakedown drive.
fark
I think I have bigger problems than those pushrods to get resolved before may 3rd.
Where do I ask for help finding a tubing bender nearby?

Any muffler shop should have a bender. If you want a higher quality system buy straight pipe from the muffler shop, with no coating and u-bends from a local speed shop, than fabricate the system.

you're in dublin oh, google shows at least 10 midas and monro mufflers. a repair should take under an hour unless the entire exhaust fell off and you didn't go to pick it back up.  Don't be that guy that leaves half his car on the track. Seek professional assistance  :cheers:

tis not a muffler. needs completely redone manifold back including 3 bungs and custom bends to be tucked up, "right" and not embarrass me when someone looks under the car. im really not worried about leaving pieces of it at wilmington since there are no "speed control devices" in the pits. I am however worried about the drive to wilmington since I am not trailering the car. Don't want to miss the race because of railroad tracks or potholes. What kind of ground clearance to do you guys build to? I've seen some REALLY low cars at wilmington but did not take notice of exhaust routing.

To be safe you need at least three inches ground clearance and be aware of what your driving on. Speed bumps and even entering gas station driveways will get your attention. Summitt and Jegs both offer excelent mandrel bends all sizes and gauges as well as straight pipe many race cars are built using pipes from those suppliers.   Theres still plenty of time to put together a nice exhaust system    :cheers:

I added airbags front and rear to my car to get ground clearance.

They were supplemental to the suspension I raced with, the car was not drivable on the street without them.
