Default Same car but so different

I just put away my '65 Coupe 327/375 fuelie, side ppies, 4:10 rear, short throw shifter and manual steering. It's loud, fast and reminds me of being 17 again. Up in NJ all we have is ethanol fuel so the summer time with 80* weather can be a problem

For the summer '65 Coupe stock exhaust, 327/350, 3:50 rear, power steering, tele column, and working factory AC. Now I feel like the old guy just cruising in a vintage vette.

Such a different feeling.

Joe, you have other problems. That is not ethanol. People use ethanol as an excuse for all sorts of things that are frankly, not ethanol. Ethanol has a higher octane than gasoline and at 10% causes almost zero problems. Post a picture of your engine from the passenger side so we can see the fuel line routing and fulie set up. Hopefully, we can help you fix your non-ethanol related problems.

A problem? In what way?

Here in the Peoples' Republick of Kalifornia, all we have is E10 and a distorted version of gasoline. My fuelie, which I drive as often as possible, runs fine on our mystery fuel blend.

What problem do you have?

I mean, gas being what it is....I'm hunting down a station about 20 miles from here that SAYS they have no ethanol fuel tomorrow (I hope) but not driving that fuelie would be a test of willpower I don't have.

The fuelie "vapor locks" once the temps get in theupper 70s. If i take it to work in the morning it's fine, leave at 3 and the car is in the sun the idle will rise and full for te entire ride home - about 3 miles. Put it in the garage and take it for a ride in the cool of the night no problem. Next dat day same thing. I see ZIP has an insulating shield. Next fall I plan n installing it to see if it helps.

That's really interesting! They're the same-year coupe with almost the same horsepower and rear-end gearing, yet the experience is completely different. I remember going over a parking lot speed bump in my '63, and it removed the dilapidated, low-hanging old muffler system; it was loud and fun! I suppose you could put a louder exhaust system or cutouts and see if you get younger. Also, I am not suggesting you should do this, but I wonder what a TKX wide ratio 5 speed would do - for your car and your health!

I think the 3.55 vs 4.11 rear gears make a pretty big different driving sensation. Add in side pipes for extra sound and the 375 will feel a lot more powerful than the 350 HP version.

Such a nice problem to have, which of 2 very nice cars to drive each day.

I agree with those above, something is not right on your FI engine and it can be fixed.

Thank you for your offer to help. The car is presently a few miles from home and I will get pictures posted. The car has been a work in progress since I bought it from a dealer in Missouri. He had the injection unit rebulit by JP and promised it was running really strong. Not the case when it arrived. It had sever trail hitching which was caused by the wrong vacuum canister as well as a number of other issues. Up to this issue which started about a month ago I had the car running reasonably good. It idles at 900/1000 and responded through the rev range. I was thinking of getting the distributor serviced over the summer.
Again thank you reaching out.

In my opinion, a good first move would be to get the FI unit properly calibrated. Why? Because the rebuilder of that unit does no calibration when he's finished. He doesn't even do any testing.

Could you post or PM me a rebuilder on the east coast you would recommend. I'm in nothern NJ. I planned on removing the unit later in the year anyway.

The ONLY rebuilder in eastern US who installs a completed FI on his car and calibrates the air/fuel under actual operating condition is:

Ken Hansen
Medina TN 38355

731-783-0815

He was trained by Jerry Bramlett (retired), the ONLY other eastern US FI rebuilder who calibrated FI units on running Corvettes.

Ken will find and fix any and all of JP's mistakes.

Thank you. I know it's been said many times but never enough about the list and the people on it who share their wisdom and time to those of us who flounder along turning wrong screws in the wrong direction. I hesitate to name names only because I would most certainly leave a deserving person out.

it's a shame so many people have JP problems. I most likely will never own a fuel car. Would love too but on here and other discussions I hear so many problems caused by workman ship.

California has a different blend that costs more to make for the summer but it is more FI friendly. In Colorado we have the cheap summer blend and at elevation it becomes a more serious problem.

If you send your FI to an honest and competent rebuilder, it's unlikely you will have any problems. Too, in the unlikely event that you do have a problem, honest and competent rebuilders stand behind their work 150%.
