I had some really good results on the dyno today.
I have a 5.3 swapped in my ford focus

engine is a stock 100k plus mile 5.3 aluminum engine from a trailblazer
lingenfelter gt1-1 camshaft
comp valvesprings
holley sniper intake manifold
102 mm throttlebody
4 inch intake with no maf
hp tuners
electric water pump
no accessories other than alternator
th350 trans
8.8 rear end
car did really good.
All runs are done in 2nd gear. I think it would make a little more in 3rd gear. but with the current gear it turns over 170 in third. I am swapping a 3.73 in later this week and will put it back on the dyno after that.
best run was 386whp
