Found on calspeedperformance.com that they have rotating assemblies for the 5.3 that include wesico pistons callies rods and crank. Has anyone built up there 5.3 with these parts yet? Seeing how it's only $1100 (if you use your own crank) might go this route for a turbo build instead of going with a 4k shortblock and then still having the cost of the turbo kit... At least for now that is still would like to have a nice boost built ls3 later on

 

For a little more you can get more cubes out of it, still be forged

 

What do you mean by putting a 4 inch crank or by boring it? They have the option to add the 4 inch callies crank for an extra 800 which according the the site makes it a 363?

 

Im still not totally sure, I really want to leave the 5.3 alone for the most part to have as a backup motor and go with like a TSP 418 or HKE boost motor. It will take longer to acquire the funds and to get it in the truck but I think it might be better. I was just thinking for the mean time add a few parts to the 5.3 and boost it maybe I will just be happy with that... Dought it tho lol

 

Boosted 5.3's are slow. Don't do it.

 

 

Lol yeah that's what I was thinking...

 

im itchin to find out just how slow... when are you runnin yours next? your new times have been "coming soon" for awhile now. i cant wait for sunny weekends in the butte, its finally summer in the frigid north...

 

I should be out there one day this weekend. 3 days of racing, I just need to decide when I'm going. Last weekend I had "driver error" and ran 12.7

 

yes i have a 5.3 forged and just polished crank but my set up is for N2O and i think the fasted 5.3 boosted is a 10.5 or 10.6 going to see if i can break the record on my little 5.3
