LT1 vs. Vortec vs. LSx

Dont do what I did (TPI 350) I dropped a ton of money and time to get the power out of it and in the long run it would of cost less to do a 5.3 swap and have more power for less money my engine stock had 210hp(TPI 350) when I was done it made 300hp @ the wheels the 5.3's start around 300hp+ (flywheel) but with tuning and simple bolt on's you can get an easy 60 to 70hp more

I didnt cheap out on my engine stealth ram injection, forged internals, splayed caps, aluminum heads & Etc. $10k invested and just redone it for more power another $3k way deep in it!

a 5.3 with the same HP would of cost about 1/2 as much! when I was shopping for an engine 4 years ago the 5.3 aftermarket was just taking off and every thing was very hi cost now its cheaper to do and with the conversion kits made easy not to mention how many 5.3's you see out there with over 150k miles on them getting 15mpg+ but the down fall is all the electronics the air intake tube on my 07 suburban fell off and true a engine code and the truck was not shifting right lol
