  1. Blitz ran a Vortec, but I believe that was in the days before the swap calculator, and a 350 pickup engine value was next to nothing.
  2. Digging up some old old memories here. I am just old enough to have gotten in at the end of Modified eliminator class racing. Back then everything was based on pounds per cubic inch, and you wanted the smallest engine possible to make your weight break. Destroking 283’s, 283 cranks in 350 blocks with bearing spacers, welding up iron heads, all kinds of fun times. I still have Jenkins book, for the year it was published it had the most up to date and in-depth info ever published. Of course, everything moved on, but it is still a great read.
  3. If I had $5000 to spend on a steering rack this is exactly what I would have. https://documentcloud.adobe.com/link/track?uri=urn:aaid:scds:US:3658522d-8307-401a-8b4f-61acf9942f2e
  4. I don’t know anything about them, but what about these new many speed automatics? I was in a meeting the other day when someone asked if they were going to be using a 9 speed or 10 speed transmission. They must be pretty strong ever since the towing capacity wars got out of hand.
  5. Last time I remember this coming up I thought it was considered a no go. Stock automatic transmission cooler connected to stock automatic transmission was fine, automatic transmission cooler used to cool anything else was points. I could be wrong though.
  6. The rack kit you are looking at probably just uses the Heim joints to look racy. Find a regular tie rod end that fits and use it, then control your bump steer by where you mount your rack. You must do some fabricating no matter what, make sure that you get the most out of your 10 points for the rack. There are many rack and pinions out there that have many different characteristics, find one that works for you. Since they don’t have any specified value listed for the rack conversion, I figure you could use a $5K Woodward if you wanted and then you can specify everything to fit your needs.
  7. That would cause me to be very suspicious of the wiring/relay. Also check your surge tank closely, they are infamous for coming full of chips, I know this one from experience. What makes it difficult for you is that it only happens when everything is hot, it is very difficult to recreate this in testing around the neighborhood. Good luck.
  8. Going forward with newer cars fuel capacity will become more or less of an issue depending on how you look at it. With higher fuel efficiency newer cars mostly have smaller fuel tanks, 13 gallons is becoming very common. The days of a 2300lb car with a 20+ gallon tank are in the past.
  9. Another thing to watch out for is that there are a lot of knockoff 044 pumps out there…
  10. If you study ChampCar results, you quickly find that one of the top 3 failures is fuel pumps. Running flat out for hours at a time causes the fuel in the tank to get surprisingly warm, which shortens the life of the pumps. Also check your wiring, fuel pumps need good strong current to work efficiently. I thought I had a better idea when Holley gave us these cool fuel pumps that are actually 2 pumps inside one housing, if one fails I have a switch on the dash to switch to the other one. Unfortunately one year at the 24hr when we had a cracked header and everything was getting overhe
  11. Tech desk ruling said conversation from steering box to rack and pinion was 10 points. But nothing about how you go about installing the rack and pinion.
  12. This is topical for me, since I am planning on doing something similar. In my case I don’t have a steering rack at all so I will at a minimum have to pay 10 points for rack and pinion conversion, but the question is what do you get for those 10 points? Nowhere in the rack and pinion swap is 10 points does it discuss how you mount the rack to the car or attach it to the rest of the steering system. The best kit for installing a rack and pinion in a first gen RX7 is the old ReSpeed kit, which has been out of production for many years, but I can recreate and improve on it. It uses a c
  13. Should run fine, the fancy new materials are only used to increase service life. On the other hand, on a stock engine I don’t think you would see any performance benefit so why give up the extended service life of the newer plugs?
  14. I agree they need the 245-15 size, but there is a small chance that if they follow Hoosier sizing their 225 will be as big as everyone else’s 245. When you read all the tire chatter, if we go down the road of a tire list it will be a list of approved tires instead of a list of banned tires. This could result in a lag when good new tire candidate is introduced but it shouldn’t be too bad. And we can stare longingly at all the rocketship autocross tires we can’t use…
