@copeman89 That's just a regular 350 vortec. Nothing high output about it. And it's not the 255HP that turns the wheels. It's 330 ft/lbs of torque. LOL!
there was no HO vortec motor for full size pick from 88-98 i know buddy has a 99 nbs 4.3 HO full size pickup i think this guy got ripped off only one set of injectors u can buy also one cam came in it u can buy a different one to put in with no problem and they never put dual 3inch pipe from factory
There was THe stock 350 vortec and then there was a 350 vortec H/O. MIne has the High output. IT has modified cam, higher psi injectors and Stock dual 3 inch pipe from the high flow manifolds back to the single muffler and a 3 1/4 in. exaust pipe
nope on all of it, My dad worked at GM for 30 years. NO such thing.
Theres one set of injectors for the VORTEC engine, hence the reason high performance people swap out fo the MARINE 5.7 mercruiser (boat) intake...so they can put in bigger injectors at higher PSI,
There was no high "flow manifolds"
By modified cam you mean stock...
UNLESS somebody installed a bigger cam, a bigger fuel pump, and ran True daul exhaust back into a single.. and told you it was HO.
What a fucking retard
Crazylegsdibben 1 month ago
you dont measure Injector rates in Psi.
Dual 3inch pipes to the back= loss of torque.
You must be one bad liar, or got lied to and are a fool.
350 vortecs only made 255hp and 330hp. The LS engines are far superior..

how did you get bigger injectors if the spider injectors in a vortec of that year are not replaceable? tell me, i'd like to know
bmxman242 1 year ago
@bmxman242 You can't. Even the upgraded spider has the same size injectors.
