ha it was a joke you ever see that one commercial?
i wasnt looking to build a race engine just looking for some info on what you all recommend an what works best.
you ever see the super stock diesel tractor pullers? they run 4 turbos with such low compression they dont want to start but once the do they create 100+ pounds of boost

Hey, I'm in PA also and I've never seen 93 sell for the same price as 87 octane, sale or special promotion. Would be a pretty bad deal for the refiner/marketer too, upgrading gasoline stocks from 87 to 93 requires millions more BTUs be put into the reforming process and it also shortens the catalyst life, that's why premium fuel costs more. The octane rating is the value that relates to the fuel's resistance to detonate, that means burn. 87 burns easier than 93, plain and simple. If a motor isn't pinging or knocking on 87 octane then all that running a higher octane will do is lighten your wallet and possibly cause some carbon buildup in your cylinders from the slower flame propagation of the higher octane gas. There is absolutely no benefit to running a high octane fuel in a stock tuned low compression engine, well I guess there is some benefit for the oil company and that helps keep my wallet full.
I would love to hear some of the other things the guys telling you that 87 is the junk fuel with dirt and grime have to say, I'll bet they have some other gems too. All grades of gasoline are run through the exact same type of filters and have to pass the exact same test standards for particulates, so keep buying premium if you want but it isn't helping you in any way.
As I have already explained in your other threads, headers and Y-pipe will do more for your V-10 than any cat back system will and gears will do even more.

I put a Borla system (headers & cat-back)on my 1999. It really made a difference when towing. Overall power was up and towing mpg was up 1-2mpg. I would do it again in a heart beat. Saving up for my 2002. Yes the V10 loves to rev and the headers really perform at 2500rpms & up. Now not towing mpgs were only up a hair.

OP there are good increases with with long tube headers.(Doug Thorley and Banks) I run the Doug Thorleys on my truck. They helped power throughout the rpm range including off idle torque. The stock exhaust manifolds are horrible and what causes the "flutter" on the V10. While long tube headers are best there still is an improvement going with a set of short tube headers and and SPD y-pipe mod. Keeping the stock exhaust manifolds and adding the SPD y-pipe will yield exhaust flutter, which is rather annoying.
thanks what would some good shift points be for daily driving?

As far as the tunes, several members have been impressed. I don't have a tuner yet but would like to get one eventually. Things I would look at would be Headers, Tuner, Y pipe and gears for the total package of perfromance modifications. Basing most of that from everyone here on FTE.

If you read the threads on the Hedman headers and the loose socket connection you will see that the issue is the socket expanding, not the bolts working loose, the bolts get loose due to the expanding socket.
