Any thoughts on this cam 215/230 .630/.630 114+8 for a 6.2. Daily driver and tow occasionally.

 

Seems reasonable, for square-port heads at least. Not so much for cathedral ports, you'll be giving up some torque especially. If your heads are cathedral-port I'd suggest dropping the exh duration back by 6 - 8° or so and making it more like 112 +4.

 

To be honest I'm not sure if the heads are cathedral or square. Here are the stock heads from the L87 of mine. They look more like square to me.

they are getting ported and blended.

 

Ah LT engine you don’t have to worry about square vs cathedral

 

Yup; whole other deal. Unrelated to "2008 GMC". Those are somewhat like square-port LS heads though.

What are we actually working on here?

 

I currently have my 2020 Silverado 6.2 having DFM deleted, cam, lifters, springs, push rods, heads ported and blended, intake ported, headers and tuned.

 

I see an interccoler in the back ground. That L87 needs boost…

 

yea I agree. I just couldn't swing a whipple with doing everything else. My main goal was to get rid of the dfm garbage. Maybe within the next year when better fueling is available for these 19+ trucks.

 

ZO6 Ted has that covered for you. He has a 22 with a TVS 2650.
