Question on compression change

I brought my head to the machine shop trying to find out the source of a water leak over into my oil... long story short, the machinist had to take .020 off to get it flat. He told me I shouldnt have any problem running 83 in it, but just wanted to pick the brains of the masses over here and see wha...

Oil on head bolts or not?

I know the steps (55, 65, 85) and the pattern, but can't find it anywhere as to whether that spec is with oiled threads or dry.... any help?

Re: 1984 F150

you can also wire in a chevy HEI module using a dspark distributor and the coil you already have. I did this on a EFI to Carb conversion on a 5.0. Worked great, plus there's not as many wires to run as compared to using dspark. I put a pushbutton in the cab for simplicty's sake, as this was just a b...

Re: 4.9L parts brands to avoid??

All i can say is that when we with the mazda trans have to R&R the internal slave cylinder. Do not do not do NOT waste any time with any brand other than the ford part from the dealership. I've sen a napa part fail in a month, and I put in TWO from the zone which were both junk. Put in the ford ...

Re: Building 300 for towing

As far as using a mazda trans, all I can say is NO. Bad Idea. The trans you have could be the best light truck trans ever made, and since you seem to have a decent budget for this venture, why not troll ebay or clist for a gear vendors or similar auxiliary trans. I love the use of low range, unlocke...

I see gray ash on several of the plugs, so does all this indicate valve stem seals? Second, what kind should I look fo...
