i did 518hp with a 224/228 cam and 2600 stall and a 3.6pully in 90deg 50%hum. so he should have 550 ish with his setup i'm sure.

 

I bet 10-11 psi and yes a it will slip with 6rib no with 8rib. What will you shift 6400 or so?

 

didnt want to make a new thread so heres my q right now i have the 3.6 with no slippage its at 14 psi at shift point , how many lbs more should a 3.4 get with no slippage ?

 

What you shifting your truck at Most Hated... We just starting tuning on my 370 w/P1. By the way im going to be trying to run a 3.5 pulley on my truck hope to be around 12-13 psi. I like to shift around 6800 or so....

 

Sweet, I will also be running my p1 on a 370. From what I have read, people don't think it will make much boost on a 370

 

One way to find out... haha

 

a friend of mine has the 3.4 with the a 112-1/2 belt (fits tight)and his getting 10-11 with a 6.0 p1 cam and trickflows 225 heads

 

65-6600

 

i would like to get 16-17lbs see how much this stock bottom can handle
