UnderCover5xSwitching from Hardtail to 4 link to lil bubbas
I’m currently running a hardtail dragster with a 440 SBC, 4.86 gear, and 33x15 tire, going 4.80s. I’m switching over to a 4-link dragster with Little Bubbas and trying to keep the same ET.
What rear gear would you recommend starting with?

CURTIS REEDI’m not a dragster guy but I’ve been thinking about your question. You’ll probably gain some weight on the four link car so I would think you might need a tiny bit more gear to get things moving but I can’t imagine I would want less. I don’t know your rpm now or what you want to limit it to at the stripe though. Tough question to answer.
On another note that’s a good running small block.
