The block is a SBF Iron Eagle 351 Sportsman

Thanks guys :)

It has been traditional to use a 71 roots or screw design. However, thoughts would be appreciated regarding a 16:71 or there abouts case, bulk headed half way back and two independant rotor systems. The front rotors could be roots and the back set screw or perhaps some other combination. Reasoning is, two smaller chambers offer reduced "pressure up" time and provide other potential control options. Plus, the concept may reduce heat soak and sustained parasitic drag. ]]> General Engine Setups CcanDo http://www.dartheads.com/dartboard/showthread.php?t=1236 Compression Ratio/Detonation Control http://www.dartheads.com/dartboard/showthread.php?t=1235&goto=newpost Sun, 15 Nov 2009 20:04:28 GMT Base line for 93 octane, supercharged, 5# boost, 8.5 compression initial, is said to create 12 to 12.5 final compression, safely.

However, the rule of thumb seems that 12 to 1, non supercharged is not safe. Why not? If the answer is only timing, then where/when does concern start, at some number on timing, RPM, fuel to air or all the above?

I'm going with a coil over double adjustable shock from QA1. I want to use a coil over so I can access the adjustment knobs easily (I know that Afco makes an killer double adjustable front with adjustments at the top and bottom # 3870 BNC but I was told that it will not work with the Global West TLC A arms). My question is I have Morroso front coil springs on the car now with the stock A arms that have a 213 spring rate, The springs that are being recomended with the coil over set up are 350 spring rate. The car weighs about 3270 with driver now and should weigh about ten pounds less ( off the front ) with the new set up. Should there be that much of a differece in spring rate from a standard coil spring to a coil over spring?
I dont know the weight of the front of the car but it has a small block with aluminum heads, no alternator, 5LB elec waterpump skinny hoosiers / Weld 3.5 x 15s, no fender skirts . The car is used for drag racing only. If you have experience seting up cars for drag racing please advise what spring rate on a front coil over would you use in this application? ]]> Chassis and Suspension BERT http://www.dartheads.com/dartboard/showthread.php?t=1234 Hi Everyone http://www.dartheads.com/dartboard/showthread.php?t=1233&goto=newpost Sat, 14 Nov 2009 05:22:22 GMT I didn't realize this forum existed....Neat idea Dart has implemented....Our interests include boats, engines, hot rods and the technical stuff that goes with it all.

There are a varying amount of personalities and levels of expertise on this board. When a question is asked, there will be varying answers. Just because answers vary, doesn't mean there are digs going on. I don't mean to be pointing out the obvious, but apparently I have to.

I have never claimed to be a professional, but if I think someone is wrong, I will speak up. It is the way that I am. ]]> General Discussion lun40119 http://www.dartheads.com/dartboard/showthread.php?t=1228
