What are your guys guesses to hp and what it would run in the 1/4???

 

Probably 260-270rwhp give or take a few.

 

265rwhp and 290rwtq. The heads and cam aren't the best, but they're decent. If you're a good driver you should hit a mid 13. In all honesty I would guess a 13.8@101.Depends also on what rear gears and tires you have

 

Well your pretty close on the 1/4 mile...my first time out i ran a 14.1 @103...thats on almost bald street tires

 

That 103 trap speed indicates a mid-low 13, Get some stickydrags and you'll be crawling at the 12 second door

 

around 260rwhp and u should be able to squeeze a low 13 with a little more seat time....
