I want to fuel inject my 350 with vortec heads, its a blue print specialties crate engine.

Its a pretty mild engine, and I only run it on the street. I want to run a 4byl type intake, but my choices are pretty limited because of the heads.

Would a Victor be too much for my engine? I really do not want to use a hsr, or a pro flo xt but if I have to I will.

 

I think a Victor would be fine if you had the hood clearance for it.

 

A Victor Jr take? You don't want a single plane for a street car unless you have the heads, cam and compression to work with it. I think an Eddie Airgap would be the best of both worlds for your engine

Another way to pick and intake is look at the RPM operating range you'll be driving in. Then look at where your cams power range is. The Airgap is a good all around choice.

 

Even for a fuel injected engine? I always thought single plane I takes we're ideal for multiport setups? I know the rpm range is high, but I didn't know if it being fi rather than carb would make a difference.

Contacted edelbrock about their victor height, it's 5 10/16". That with thier 4 barrel tb which is 2 1/2" high should fit under my hood just fine. They told me their tb used tps, and iac motor from an ls engine. Not sure if that will be a problem with megasquirt.

 

A single plane multiport intake would be a good choice. Those thinking about dual plane intakes are stuck in carb brain thinking not fuel injection.

 

The engine you have chosen, the cam isn't really for fuel injection. But I looked on the same site you found that engine and for $300 more you could get one with a roller cam and aluminum heads. A few more HP and torque, And the cam is a bit better for fuel injection

 

Yeah, I wish I would of waited to buy my engine until the truck was almost on the road. I bought my engine in 2008, and there was not too many options for the engines.

Dumb question, why is my cam not a good choice for a fuel injected engine?

 

I figured the OP was asking about a carb, sorry.

 

it have 112 Lobe sep, but even with stock ecm you should`n have problems to tune it, i will go with 1.6 rocker arms to get some more lift that bolted with single plain EFi should run pretty well.

 

Well right now it just has stock stamped steel rockers so I wouldn't be against upgrading lol.

Will 28lb injectors be enough for the engine, or should I go with 30lb to be safe? Any opinions on race pumps high pressure mechanical fuel pump? I've read good and bad reviews, but it seems like guys that use the race pumps regulator don't have problems.

edit: Just called race pumps, they dont suggest using thier pump for fuel injection, so I guess I have to run a return line, I havent found a returnless fuel pump. This pump looks like it will work,

but will my 3/8 hard line be too big for the pump? What about the return line? 1/4, 5/16 or 3/8. Will the size effect the pumps ability to build pressure?

 

Dumb question,

Is it ok to mount the regulator back by the fuel pump, or do I have to mount it after the fuel rails?

 

Notice this section is called Alternative Port EFI Intakes


Not the 1st time you have put your foot in it ( the Vortec heads ) in the short 2 weeks you have been here

You need to READ what is actually being talked before typing

 

you can , the late GM cars like the

 

You can , some late GM cars like the Vette have the reg by the pump with a single line deadheading to the injectors

Do a Google search , thee are arguments for both systems

 

I've read about them, and about how people are not fans of it. From what I've found, the regulator is built into the fuel filter? Could I use that with an aftermarket inline pump? I'd assume there not adjustable.

 

If I was doing this build I would be looking at the Walbro 255lph in tank fuel pump or the walbro 400. , The 255 is good for an engine running up to 400 hp, But I think that is pushing that fuel pump. You would have to run return lines. I'm not sure what size you would need, I re-ran new lines for my car but I ran 1/2 inch to and from stainless steal, But I choose that because I'm running ethanol fuel I also choose the walbro 400 for E-85.
