Hey guys just another opinion here besides mine, I'm looking at dropping pulley again and installing 1.9s for now before I take time out of my busy schedule to throw my stage 3 p&p heads on.
Currently I'm running an l67 block with SD headers and a gen v with a 3.5mps and e85@20* timing no kr which so ever wideband AFR at 11.2
Thinking of a 3.3 with 1.9s on 18* timing any suggestions here or opinions before I make the move.
On a gen 3 top swap I ran the same setup with a 3.2mps with a gen 3 pushing 20* so I'm curious as the gen v equation would be considered a 3.1mps if it was a gen 3.
Thanks
