    That is a nice ride. What is the device on the left front inner fender?

      I think it's a alcohol injection system, I know it has one.

            A good friend of mine and I built that car as the car was originally mine and then went to my friend and then to Pat. The engine is .140 overbore with all cylinders sleeved, Ross pistons, Cunningham sprint car style connecting rods, Chevy valves and springs with hard seats, ARP head studs with copper head gaskets, aluminum timing gear and an Isky ST5 cam. Pat added water injection for anti detonation protection. It has a Borg-Warner T10 trans and a Hurst shifter. 58 Golden Hawk dash, steering and suspension parts and seats from a GT Hawk. Pat also added Fairborn flanged axles to the differential. As an added bonus, the car has never been wrecked and has under 100k miles on it. Bud

              A classy ride, for sure. We don't see too many coupes up here, yet, but summer is coming

                      That's a hard core build. The rods and pistons would be more than $2,000 today.

                      Just asking, why was it necessary to sleeve the block for a .140" bore? Most early blocks would take that with no problem. Was it a late full flow block?

                        Holy cow, amazing engine specs! I'd love to take it for a spin. Luckily the rest of the car does nothing for me, so I'll not be pining away Not to say there's anything wrong with the car, it's just really not my cup-o-tea.

                        Now drop that engine in a Daytona........

                        I personally have never seen a dog scalded, so I have no feel for how fast one would be, although I imagine it would in fact be fast. Maybe it's time to experiment. My son has a dog, an annoying Lab mix. Hmmm...... C'mere, Amber...........................

                          Its funny you should mention a Daytona, cuz that is the car Pat is keeping for his driver. A well built 289 in a Vanilla Wrapper 63 Daytona.

                            The block is a late full flow and we hit water on a couple of cylinders when we bored it, that's the reason for sleeving the rest of the cylinders. We built the engine to replace the original R2 engine in Don Tucker's Avanti with a Paxton turned up to about 10lbs boost. The engine with 10.5 to 1 compression and the supercharger was just too radical for a street car so the original engine was rebuilt and installed and Don sold the engine minus the Paxton to Pat to use in the 54. The engine at this point doesn't have more than 5000 miles on it. I did some distributor and carburetor work on the car not too long ago and I will guarantee that the car is fast as I've driven it in recent history. Bud

                              Thanks for the info, Bud. I figured it had to be a late block.

                              Off topic again, but did you hit a water passage or the oil passage? I've never seen water at .140", but I have seen one late full flow block break into an oil passage where the Stude foundry changed the core to add the full flow.
