It’s a different world today and I’m glad I grew up in a time and area where we worked, street raced almost every night and if we lost worked again. Nitrous was available but we didn’t need it to run 11’s back then. We had crap parts unlike today so honestly it would be harder for me to build an 11 second car than it would a 10 second car. ProMax heads and a good convertor is a great start to any 10-11 second build on a budget. Throw in a good 750 Holley, port matched intake, .480-.520 cam, and 3.55-3.91’s and you are making bacon.
