We put a TSP 220 cam in my brothers 5.3l ecsb a few days ago, its still pulling hard shifting 1-2 and 2-3 around 5800. How high can we safely turn this motor? We prob wont go much higher on 2-3, but it sure feels like its leaving alot on the table at the 1-2. He has PAC 1218 springs and TSP rods.

 

i have the same set up except i have prc duals got the shifting points at 6200 1-2 and 2-3 with rev limiter at 6500 and towhaul is just 100 rpm higher on each shift

 

I shift a 6400 on both shifts and even did so on a 150 shot of nitrous.

 

got mine set at 6350, but it shifts close to 6400.

check out my dyno graph of the same cam, you can see were it pulls to

 

6400 here.

 

6000 and 6600 in tow haul

 

tsp 220 comp 918's and tr hardend pushrods , shifting 6,500 1-2 and also 6,500 2-3 6,700 rev limiter ..

 

I would go more around the 6500 range

 

get in the truck set it at 6200 then again at 6400 then again at 6500 and see where you feel like your truck isnt pulling anymore. id spin as high as 6400-6500.

i spin my 6.2 to 6800 and im raising the shifts bc it just keeps freaking pulling.

 

Take my advice with a grain of salt, cause my cam is still sitting in the box, but when I get everything together I'm planning on having the rev limiter at 6500 and 1-2 and 2-3 at 6200.
