5.3 advice
I'm now putting a cam in my 2000 Silverado with the 5.3. I've got a set of cnc 243s that have been milled .030 and a 228/230 585/585 112 cam laying around.my question is is my compression going to be to low with those heads and cam?

well i just put some milled .030" 799 heads on my 5.3l mind you there the same casting as 243's. before they milled them they measured 65.5cc. didn't get the measurement after milled but they take off 1cc for every .0065" milled. all the calculators put me right around 9.9:1 compression.
this is just my opinion, that cam is a little large for a 5.3l in a truck. might be fine in a light car but not in heavy truck.

I guess I'll try to use my 243s get a more truck/ lower compression friendly cam . is 224 or 228 Texas speed cam a better choice for my dd.

just had tranny rebuilt and oil cooler added and plan on running a circle d stall unless anyone else has better thoughts? I know how important a good stall is but is there any ones out there alittle cheaper . Are FTI converters any good? ... Budget is way blown for my dd lol

as far as a converter i think that circle d is about as cheap as i would run. also they are like 8 miles away from me so if i don't like it i can just throw it threw their window. [/QUOTE]
That would be a pretty far throw from Nebraska for me lol ... Ive never heard anything bad about them and there performance one is only 100 more than tci ones.. My stupid *** didnt even look a btr for head gaskets when i ordered my cam..
