So, a while back I told you guys I took my truck to the local dyno shop and they said I could use larger jets on my stock 2bbl carb. I only bought the next oversized jets, because I read on this site that other members have actually installed smaller jets (or maybe one jet?). The dyno guys installed the larger jets, ran the truck on their machine, and said I could go up another size larger, but I didn't have anything larger.

Anyway, help me understand the differnce between putting larger jets in a 2bbl versus installing a 4bbl. I'm assuming the 4bbl allows more air to cycle through; therefore, you can mix more gas?

I don't have any desire to pursue the 4bbl mod, just curious what the difference is compared to rejetting the 2bbl. I may buy the next larger size jets if I take it back to the dyno shop.

Thanks,

Clarke
