What is the hp rating (iyo) on a stock tbi motor would be at the crank with vortec heads?

 

[GMstrong]

Atleast 250hp.

I heard Vortec heads is one of the best mods you an do to an sbc. That's what i plan on doing when time permits. Then get a vortec to carb intake, and you can buy a varb to TBI adapter plate online for like $40.

The thing with the vortec mod is you're also putting in a better intake along with heads, so with tbi mods, a cam, vortec heads, intake and higher fuel pressure you could get 300

Money spent where it counts (under the hood) over money spent making it look cool. In my opinion.

In my case, I already have the power...

VORTEC POWER!

and when she croaks I'm sticking in a crate motor with chargers...

A Jeep XJ steering shaft! By far my favorite and most effective mod below $50.

Vortec heads are a good upgrade, but you have to get the TBI to Vortec intake manifold made by GM Performance. Either that, or get a Vortec intake for a carburetor, and get a tbi adapter plate.

How many guys here have done this? And where can you get a tbi adapter plate?

"250 horsepower?!?! Oooohhh, aaahhh, amazing!"

Anyways, to the OP, as said above Vortec heads and a set of long-tube headers would be interesting. I think if I was really serious about powering up I would look into a carb setup. I don't have any experience with that mod but I would seriously consider it. There are lots of other people on this forum who could help you.
TBI engines are great stock but are very limited by the fuel injection system. Nothing wrong with it, it just becomes the limiting factor pretty quickly when you start modding.

My 2 cents.

That's 255 hp, which is 25% more then you got stock...

But yeah, I see your point, I'm just playin' with you TBI guys
