I have been stumped for a while about this car. Ran quite decent considering the low compression and race gas. He wanted to go faster so I suggested he yank the stock eddies off and get them ported
He did( and by someone who has done plenty of them with proven results) and the car has struggled to run even close to as well as it did before. I suspect the compression is even lower now than it was and the race fuel has had even more negative effect
