[QUOTE="OLD H2S, post: 1361491, member: 20979"] Well... That is a tough question. I would like to run this car At Summit Point more frequently, I did last weekend and it's weak points were showing. The last two cars I built from scratch, a 1969 Road Runner 440 and a Mercury Marauder 4v Terminator. Both cars were 4500 pounds and just over 500 BHP each, so I am used to big sleds that were not really good at road racing but fun to go 150 mph. Those two cars sucked up the last 20 years of time and money. This Mustang I bought new for the wife and have not done too much to over the years, just a Steeda stage 1 kit. Now she has a new car and the Mustang is a spare. It is 3400 pounds and 100 inch wheelbase with a V8, sounds like a BMW killer to me, parts are cheap and diverse which is a plus compared to the competition. There were some other Mustangs there last weekend , all but one were dedicated track cars. The lone street car was 275 BHP and running in the advanced group and munching on 3 Porsche C3's. I have kept this car because it is so much fun to drive, you really have to work hard with only 170 BHP. I have had 2 Cobra motors so far, one was a Vortech and the other was an Eaton so I am over the need for speed. I could do the Trick Flow heads but I like the NPI challenge, I have some used Manley H beam rods and a billet oil pump around, the stock cast crank is plenty good for a 300 HP build up, I am thinking of a stout, low HP, high RPM street car that I can beat on. Right now I am working on the brakes, handling and getting more seat time. This porting side job was just something to do while waiting for parts to come in, the valve seals are shot and it is burning oil bad so while I am in doing the seals I might as well do the cams and put in the good oil pump.
