Geez

I have tried every shade tree trick I know of on GT.
1964 273 4 bbl 4 speed.
New points adjusted to .017 , and again.
Solid lifters , adjusted 10 intake , 20 exhaust.
( I guess those arms line up with spark and exhaust ports , and , does the gauge need to clear it ALL. Or just the 'edge'. )
Sounds really good until a trip to the store , then it pops and putters and acts like a butt head.
I need to get this right for my son Cody.
...just don't know how to proceed.
(Cody is my son who had the terrible accident last year and wants to have freedom to go again)
Thanks in advance guys.
