anyone running a 467.7? or have any info on it how it goes single route. i know i saw a guy on here whos running it, but i cant find the post for the life of me!! probly gonna go with that instead of my 300 series. seemslike everyone i talk to likes there 400 single better and spools decent still. especially compared to a 366 they say
I had a s366 from the start I put a disrepute WW2 in it a made a difference in over all. But I had canned tunes. Swapping to custom tunes when I drive it again but it was a completely stock motor at that time now nothing on it has been untoched.
on a 371 with stock fuel and just a tune, guy made 671 HP... i run a 367 and i dont think im hitting 600. should i be that far off? possibly a weak tune? im about to go 467.7 shortly, but i love how my truck drives currently. just looking for more power so im on the fence for sure!
