OK would it be better to get a used tbi intake that was bored out to 49mm to include the. tbi was bored out to match or a eldebroke performer with my stock tbi I've been reading gains with the eldebroke compared to stock is not that much. And doesn't floe all dthat better the used is only going to run me 180. Compared 300 + to get bigger tbi. N edelbroke

 

get the holley projection.

 

Yea way to expensive I could just get a 454 tbi n bore it out

 

He's talking about the holley pro jection intake.

 

Oh OK just check it out does it flow better than stock intake being bored to 49 mm including the tbi being bored to 49mm I'm trying to get best bang for buck cause Holley is 195 with out the tbi the bored 49 mm tbi and 49 mm intake for 180

 

So what's the best bang for buck if I get the eldebroke or Holley intake I be using stock 5.7 tbi on top of that so what real gains I will see if any

 

i have the edelbrock on my tbi 350.the only thing i liked about it that it was a "bolt on" replacement.i def lost tq but gained hp around 2000 rpm.to be completely honest the best bang for the buck is a carb intake you would have to drill and tap the brake booster line though and custom fab a tv cable.

 

Better flowing intakes and throttle bodies are great if the heads/cam/motor can actually use it.

 

Yea my heads are getting port and polish gasket match and I plan to upgrade the cam exuast is 3 in I upgrade

 

i cant agree any more with infernal,I would do a mild cam for example Sum-1103 cam is a great cam thats the one i will be throwing in my tbi350 that cam with vortec heads and a carb vortec intake youll be happy!

 

Yea I agree to I'm getting cams later and port n polish head till I get better heads and roller setup can't do everything at once but I agree with you to I'm just taking it a step by step and think intake and tbi need to be upgrade neck I dnt want to bottleneck engine

 

TBI 350? Whats it out of?

 

89 silverado

 

Gwarren if you were referring to me its a 90 gmc sierra came factory with it.Im still debating on the cam swap i can get a LT1 with 120k on it for 220.Owned by an older couple.

 

You probably should move up to something better than those swirlport heads.

 

Yea that's my next investment heads and cam

 

Maybe in couple months ill get some vortex heads

 

Isn't the lt1 cam is a roller cam and all truck tbi engine didn't come with rollers from factory unless it was out the car version

 

Im not talking about the cam im talking about the whole motor.Yes the Lt1 cam is a roller but some truck have the opinion to put a roller in without major mods.

 

Oh OK gotcha yea I plan to switch it to roller when I get vortex heads lt1 is a good engine

 

Would the lt1 have the torque to pull all that weight cause l05 makes alot of torque down low I could be wrong

 

Yea the LO5 makes good low end tq.A Stock B body LT1 makes 260hp and 330ftlbs.But i heard just with headers you can get an easy 15hp.Im going to be doing a swap either way LT1 or a vortec 350 this TBI 350 isnt cutting it anymore and not really worth it to buy heads,cam when i can get a better engine all the way around for 220. I think you should take this into consideration also.It depends what you want out of your engine.Me i like a motor that has some *****.

 

True I'm saving up for a ls1 swap that's my end goal... but my 305. Blew head gasket so I swap tbi 350 cause its a easy swap since its my daily driver

 

And ls1 pretty expensive
