I use NGK non-projected tips in a heat range compatible with the application. I'd start out with a -7 plug on a street car. machine shop owner and engine builder

What is so different about your combo with the same identical head that requires it? My guess is it's a Band-Aid to cover up other issues you may not be aware of. Now, before you chastising me, I've put many Indy heads on small block combo's and I've never had to run more than 35 degrees to make the best power. as far as reading your plug for timing, perhaps you're just running the wrong plug. Okay, flame away now. machine shop owner and engine builder

mopar dave master Joined: Jan 2007 Posts: 8,042 Mt Morris Michigan	maybe I do have the wrong plug, but this plug(ngk 5671a-7) has stayed the cleanest and looked the best out of the other dozen plugs i'v tried. does a flat top piston generally require different timing than a dish piston? I have a friend that has a 440 small block with chapman w7 heads and has found that 38* works best for him with 11.8 comp. http://www.youtube.com/watch?v=aIxaesJ190U http://youtu.be/lCZAaN7fFLg

Looking at the Indy chamber, im suprised at the amount of timing some of you are running.

My deal was way rich for engine masters that's just how you have to run that deal. But still it still wanted 38-40* on pump gas in a car and this was 10.75to1 flat top. Guy on moparts has the engine in a D-50 truck and it runs well.

Turn it back to 36 and it would kill exactly a tenth in back to back passes. Throw same heads on a 13.3 dome shortblock and ran best at 32 69 Dart GTS A4 Silver All steel, flat factory hood, 3360race weight 418 BPE factory replacement headed stroker, 565 lift solid cam Best so far, 10.40 @127 1/4 1.41 best 60 foot 6.60 at 103.90 1/8
