bad vibration

The roller cams started in 1996
Anything older has a flat tappet and will most likely also have worn down lobes

I think you can reuse the intake from the older engine on the 96-99 vortec by drilling out a couple of holes

You can't do that. I've never heard of anyone doing that. You would have to drill at the exact perfect angle, tap it perfectly with the correct size and in the exact perfect location.

Plus the bolts are not the same size or length for 12 bolt and 8 bolt intakes.

Not all vortec blocks have the drilled fuel pump boss for the mechanical fuel pump.

For this you can always use a low pressure electric pump with a pressure regulator and mount it in an inconspicuous location. Or get an engine with a mechanical fuel pump provision. Alot of times, engine remanufacturers will drill the required holes for a mechanical pump on blocks that don't have them already so they can be bought by people who want one or the other, carb or efi. This expands their customer base and it's helpful because if you use efi and need a block off plate for the mechanical pump boss you can get plain Jane or fancy chrome or coated ones for pretty cheap.

Ok, whats a  vortec 350? Can i still use my original intake and carb? Does it look like a normal engine?

Remember, i'm old school, real old.

I wont have to do this to my truck will i?

UGH! I hope not! That is the fugliest abortion made of a decent looking truck I've ever seen. Just my humble opinion however, YMMV

[philo_beddoe]

I think its a shame and waste of a truck, what if he hit a big poshole or speedbump, it would crumble.

[VileZambonie]

Well unfortunately this guy doesn't know what a Vortec means because both engines are 5.7L TBI's. They're both still good engines but nothing special.

[philo_beddoe]

Can a TBI have a regular carb or must they be fuel inj. ?

[blazer74]

TBI is fuel injection.
You can run a carb on an originally TBI engine with some changes.

Not all vortec blocks have the drilled fuel pump boss for the mechanical fuel pump.

I should have said vortec headed blocks

[Greybeard]

  but should a TBI have a PCV that runs to the ALB's or the TCI sourced TC? Or maybe the EFI should be MPI instead of TBI to increase the MPG and MPH at a certain HP? My head explodes with the use of all these acronyms! In my courses at school I have no less than thirty acronyms to learn this term alone. Does anyone speak standard American English anymore?!?! Sheesh!

[philo_beddoe]

Yeah me! I dont know one of those acrnyms. I'm gettin a chevy 8 cylinder 350 small block with a cast iron gm intake and a qjet carb. Old school simple.

Hey fellas, this really helps me.  TYVM........I've already made a paper copy for even quicker access.  This will quicken up my search when I see an Acronym, I don't remember, or even know.  At least a better idea before I start to google it.
