73 Duster build named Fred

It’s not his converter. He is getting his converter stall raised to 5800-6000. Then bang 9 seconds
OK I didn't realize that. Yes, if he's gotta get his tuned-up, he should aim higher in stall. I'm not sure that'll get him into the 9's but I'd guess the weight being just over 2800? so if there's 575HP somewhere it can get there. If over 2900 then he might need more parts.
