Hey guys I have 5.3 in my 2000 ext cab Silverado it has 410 gears truetrac posi CAI long tubes & tuned by cal speed. I am doing a cam swap I'm putting in a 228/232 110 lsa 600 lift @.50 Its a TSP cam with their 660. Springs and 7.400 PR, I'm also doing LS7 lifters , ls2 timing chain , and P&P 243 heads and bigger valves and stock ls6 head gasket with ARP head studs but I want to mill the heads .30 to get stock compression but I'm not sure if I will have pvt issues please help thanks

 

Most people are going to tell you it's better to measure to see if you will have pvt issues.

On the heads, how big of a valve are you going to? The 5.3 block is a small bore motor and your options are limited, if any.

For a otherwise stock 5.3, your cam selection is big. I see no mention of a stall but you do mention you have gears.

It's going to be a dog out of the hole with a stock converter.

 

Wrong cam for a DD. to much dur.

 

I will be using a 3600 or 3800 stall and I believe 2.02/1.60

 

I know a couple people who run same duration cam on 5.3 just different lift and lsa and they perform good

 

I just milled my 243, took off 30 and had them CC'd after which measured in at 61.05

What are you intentions/goals for the truck?

 

400 hp to the wheel all motor and spray a 75 or 100 shot sometimes
