I think with the torque thrust 2s..you should be well over 500

J/k

I would say about 390ish

 

Thanks
What should my trap speed be at an elevation of 3600 ft? Stock it ran a 13.8@102 with a 2.2 60 ft on street tires. I am running 315/35/17 Nitto Drags but haven't been able to go to the track.

Thanks

what kind of heads?

 

415+rwhp id guess

 

241 castings with 2.02/1.60 valves. Ported by a shop in town. Did a nice job on them. I can't seem to find the flow sheet. If I do I'll post the before and after flow #'s.

Thanks
Ever

 

Sounds about right if the flow #'s are correct on those heads.

 

are they LS1heads? 5.3's?

 

LS1 5.7 Heads.

Peace

They have Ferrea valves and ex-616 springs with titanium reatiners.

Just get it dyno'd and take it to the track. That's the only way to find out the answers to your questions.

 

he says they flow 300cfm@.550

id guess 425+ with a good tune.

 

Thanks!
Ever

 

I got 405RWHP & 385RWTQ after tuning. Is this OK?

Thanks
Ever

 

if its flowin 300 cfm then i think so esp with the tune, i woulda thought more around 415 but hey only the track will tell.

 

I'll be running the car next week. We'll see what it runs.

Thanks
