    New best 1/8 mile 6.65

    5600 to 5800 RPM would probably be a good shift point for that small camshaft- anything higher than that would be out of the HP/TQ power curve. Also you are probably leaving a little bit of efficiency out back on the table with that looser (18 blade) TQ but the looser TQ will definitely sixty...

    Timing Chain broke. What's a good replacement?

    Make sure when you remove the front cover- inspect cam tensioner . It should be a comp cam PN# 249-269 steel roller bearing assembly with shims- not the stock spring style tensioner bc you have a roller camshaft according to your threads posted. You will have to shim the roller button to...

    Timing Chain broke. What's a good replacement?

    Wow- I'm very surprised those cylinders held air without a major leak- like I said earlier, you gotta be one of the luckiest GN guys around if there's not any damage in the valve train. After you replace the timing chain and remove the oil pan to check for any metal particle from the chain...

    Timing Chain broke. What's a good replacement?

    Like TType white said- make sure no damage occurred to the engine which is almost impossible bc Ive broke two timing chains over the years. One driving about 15-20 mph and one racing the car at about 130 mph. The timing chain that broke driving slow did the most damage to the valve train- bent...

    Timing Chain broke. What's a good replacement?

    Make sure you do thorough proper leak down test- then install the timing chain and perform a compression test. If those two steps test good- then pull the oil pan and remove all the metal particle from the broken chain. I've never seen a timing chain break and not cause any catastrophic damage...

    Timing Chain broke. What's a good replacement?

    Most people are using roll master double roller timing chain that TA performance sells. You more than likely bent some valves on the cylinder heads as well- a compression test will confirm which cylinders has the bent valves. Things to prevent this from occurring again- make sure you install...

    RIP Red Armstrong

    I agree with you Brian- we lost another wealth of GN knowledge- we as GN people need to pass all this info down to each generation in-order to carry on the tradition and love.

    Fastest THS times list

    I ran my personal best THS pass of a 9.525 @ 134.55 mph which eclipsed the old THS record pass ( 9.526 ) by .001 that Sean Hayes set in 2015. The pass would have been even quicker- if I did not have to lift @ the 1000 ft mark due to my ALKY map sensor failed which cause the O2 corrections to...
