they look really good to me....the longer I play with these things, the more I believe that Lawrence Conley was right...raise the compression, lower the timing and crank the boost up....
wasn't that what Dan (Grumpy) running...I would like a new crank, myself
Sexy Earl. What kind of valve clearance do they have.
these factory cranks have millions of cycles on them...we are on borrowed time...all of us

The 6466 is currently only available in a DBB version...and it's pricey. Wondering if Bison could build it in a JB version. Steve...would that turbo have enuf flow at 28 PSI for these TA SE heads I have here? Dans block was girdled.

Granted very few of us have daily GNs that rack up 600+ miles a week but I like the added gas mileage and throttle response. It's also a great way to avoid having to buy a high stall converter to patch a soggy engine.Quote from: Charlief1 on October 21 2014, 07:45:52 PMSexy Earl. What kind of valve clearance do they have.Now you know that's overly simplistic Charlie The correct answer is ''it depends'' I've got well over .520 lift with a 215/220 cam and clear with no problem...contents may settle while shipping, ask you parents before hotrodding, void where prohibited by law
Quench! no one talks about quench these days! But, if you want to minimize detonation you need to. Funny, I run about 9.3-1 compression on both of my cars. The car with the stock cam has no problem running 26 psi so maybe quench is important? I have hit 30 on the other car with the 210 cam without detonation. Of course, it can be hard to have detonation when spraying alky so I cannot stay for sure.At one time, I ran a 221/221 flat tappet with that compression. It needed a bit more stall that the 2600 converter, but when it hit 5000 rpm, the exhaust sounded like a 390 Ford with a good cam and steel packs. Felt like it downshifted. Almost as good a sound as a P-51 making a fly by Any way, I love compression. I hate cars with loose converters that don't want move when you ease down on the pedal
