would this part add decent power or just a waste of money going on a 350 with a 305 intake and tbi?

You can't make decent power without a nice set of heads and cam. The intake combo listed there at Jegs is decent and is better than stock 305/350. You will gain some torgue and a few hp, but nothing significant.

right now car has a small cam and makes good power till 4k and falls on its face. has a stock 350 block and heads at the moment. have a set of 1.6 rockers waiting to go in. exhaust is 100% new with edelbrock headers and ypipe

The intake manifolds for a 305/350 are pretty much the same. The Edelbrock 3704 flows better than stock but the bores are 2mm smaller than stock, lol. I usually take the 3704 and have it bored to 46mm or 50mm for more flow.

I have a stock manifold bored to 50mm that was just cleaned and powder coated with a nice matte black finish. I also have tbi base units, sensors, etc.

would it just be a waste of money picking up a holley tbi unit over getting the bigger injectors

In my opinion if you are running over 325-350 hp then go with an intake bored to 50mm with a 454 base unit and 65lb cop car injectors with a little higher fuel pressure than stock 13psi. You may need to run 18psi or so.

You will obviously need to burn your own chips

and that brings about another issue, no idea how to burn chips

Brian Harris from Harris Performace (tbichips.com) can assist you in that department. Contact him and tell him your plans and he will give you recommendations on the setup best for you. Let me know and I can hook you up with injectors, etc.

will the 7.4l tb work on the small block manifold?

It will only work on a small block manifold if the manifold is bored to 50mm or if you purchase an adapter from TransDapt that allows the 50mm TBI to transition to the 44mm(?) SBC intake.

You can build that kit from jegs for half the price.

You aint kidding. Outside of the Manifold and TBI, you might spend $200 bucks, if that.

For real, i never buy kits, they tend to be more expensive and it always seems you need to run out and get something during the middle of the project because its not everything you need like it says it is.
