well with the 223 225 564 571 114 cam I pulled a 1.73 60' and the same with the 226 226 585 585 112 cam, ran a quicker 1/8th mile and a better 1/4 mile time, now not by much but with a 2500 stall getting me off the line with this BIG cam as everyone says it does very well, I say put it in there, it won't pull as high as 6800 but it will spin very well to 6500.

 

I just noticed its a 4.8L, well that changes every thing lol, you will need a 3500 stall for this cam, just not enough tq to get it off the line. But on another note it will spin to 7300 rpms.

 

I see.. I dont wanna have to change my converter..

 

if you want to stick with the 2800 stall you will need a smaller cam... you could go with a tr220 or something maybe try to tr224 i dunno, but you probably would want to be spinning your engine regularly to 7300 rpm either

 

Well welcome to racing a truck, top end is always going to be a problem for us vs. more aerodynamic vehicles. My advice is not to take a close race any furthur than 80-90 mph because most cars will come by eventually. Probably help keep you out of trouble too.

 

You have a point..lol I heard the TR224 would be good for what I want... But had to ask.. This cam wouldve been a great buy..
