So you have nothing to add to solve the author's performance problem but support hijacking threads with unneeded, not asked for EFI advice.78-200-C4, He is within the forum rules, what you are saying is not..It is that simple.
Reviewing the original post and one later comment by the author shows that an expensive $1757.75 complete Sniper system is not an option. No advice was asked for concerning an EFI system. A 1757.75 Sniper system can end up being a pile of junk on a garage floor when RFI problems present themselves. I also doubt that the original low amp RFI noisy 67 alternator will support this system. So now we have another cost.
I have read the Holley forums and they convinced me that I would never buy a Sniper. My neighbor who is retired garage owner removed a Sniper system from a friend's car then installed a Holley carburetor.
I once had a complete rebuilt 200 that would not get out of it's own way. I replaced the restrictive muffler and that cured the problem.

"Looking for a little advice. Just got the 67 Coupe on the road 6 cyl, AT. Bought it a year ago and we did a lot of work to it. It was a running driving car when we bought, although not street legal. I believe I have the original load-o-matic distributor with a petronix module, and I have a Holley 1940 1bbl that I rebuilt. The engine runs smooth at idle and has 180-190 psi on all cylinders and vacuum is steady at 18. Timing is set at 12 degrees. C4 trans that shifts thru all the gears smoothly. However, when I get on the gas, the car cannot get out of its own way. No power, no real ability to get up to speed.
I’ve done a little bit of reading and found that an HEI distributor upgrade could help (or a duraspark II). This will be a daily driver for my son, his trip to school is about 7 miles. I just want to make it drivable right now, and we can update/upgrade as we go forward. Any advice/input is appreciated. Thanks."
"I was seriously considering the Sniper. I have a FiTech on my 1970 Bronco.Cost is the issue for the sniper right now and I really needed to get the car on the road for my son. Maybe in the future."
