ok so i was thinking in class today which would be more preferred, a 305 tbi that was supercharged or a completely stock 350tbi? which one would you chose and why. but from the perspective of if you do get the 350 you cant mod it.

 

the bigger question is

do you feel inferior having the 305 TBI? By saying that you are going to S/C it in the future will that make you feel better?

I suggest that you look into the cam/heads and computer of the TBI 305 and understand volumetric efficiency before engaging in theoretical discussions without a level playing field for both engines.

sorry if that seems harsh but you need to understand exactly what forced induction is and what is needed to benefit from it.

 

Here's a simple answer from a simple fella - unless you have alot of time to play, alot of money to spend, and don't mind giving up in the end and swapping to a larger/different motor after all that time/cash spent - stay away from exotic thoughts of anything, let alone a 305 TBI.

For what you'll spend just trying to get any kind of power-adder to work with a 305 TBI setup, I could do an LSx swap and in the end, You'll still lose.

There's just absolutely nothing about a 305 TBI setup that's worth spending any time/money on. Face it, the 305 TBI has been available for nothing to anyone that wanted one for almost 20+ years - if anyone could have made something special out of a 305 TBI (or even anything TBI), it would have been done, and the results published, and everyone would have jumped on the bandwagon.

Best thing you can do to a 305 TBI is cruise slowly and enjoy the gas savings, or sink the entire engine in the lake and swap for ANYTHING else.

Folks - don't rag me - I'm not a TBI or 305 hater. But, you must admit, we've all been there, done that, was dissapointed in the $-per-performance increase gained, and we moved on. After 5+ years in these boards seeing all the "I wonder about X with my 305" - folks just need to do a little research and see that there's really nothing much that can economically, easily, or quickly to do to the poor little motors but trade up.

 

If I had to choose I would go built 350 TBI over a S/C 305 TBI.
Straight forward and less accessories.

 

I'd go with the 305 supercharged ONLY because I love the whine...

 

This would be YOUR whining after you spent all that time/money to get it to run and still get blown away by a Nissan Quest minivan? Is that the whine you refer to?

Or maybe your whining about having to LIVE in the car after the mother/wife/significant other threw you out of the house after spending all that time/money and still can't win a $20 bet from a Honda?

I'm just giving you a hard time here!

 

LOL my mom has a Nissan Quest and I highly doubt she would beat my bird! I would even let my dad drive the van just so it MIGHT have a chance! LOL

 

My wife's mother had a 1995 think it was, had like 360hp V6 under the hood - with 5 boys in the back ages 10 - 15, the wife blew away a mid 1980's Mustang 5.0 from the light - some of those minivans really fly!

 

What!?! No way.....360hp on a minivan? Why? That's just sad if it's true.

 

haha the whine in both senses then I guess. but if it really did have 360 horsepower I might look in to buying one.... HA yeah right, I'll drive a 2.8L camaro before a minivan and a NISSAN at that!

 

Built 350 with tuning and heads. you'll have more power than a stock supercharged 305

 

correct

but you aren't playing along with the hypothetical, unlevel playing field

the choices are

supercharge the LO3 keeping the heads and cam that are already maxed out with respect to flow.

bone stock (probably truck) chevy 350


those are your 2 choices

 

bone stock 350 is what I would choose. Because later on it will benefit from mods more. I did misread it thanks for the clarification

This s/c is over 2200$, wich should be anough $ to make more power by building the 305 then by using that s/c on the stock LO3.

 

$2200 is enough to do an LS1 swap and forget the rest entirely!

 

it's also enough to get one of the 290 HP Goodwrench long blocks and have a warranty, a new engine and peace of mind vs a used engine.

Either way, $2200 could be spent wisely.

 

i have a hard time believeing that 2200 is enough to swap in a ls1. thats what i plan on doing whenever i graduate and dont have to worry about paying for school and stuff.

 

Local club guy got an LS1 for $1100 complete, does it take more than another $1100 to do the swap? LS1 is "old news" now - everyone wants LS-whatever is bigger (LS3, LS7, whatever) - LS1 is hitting 5-12 years old now. The prices on LS1's are on a downward spiral.

 

And, most come from wrecked F bodies and they came out first in 98. The vettes in 97. So, those LS1's tend to now have high miles so you'll be swapping an engine that needs to be rebuilt.

 

from what iv read everyone says that getting the motor is the easy part. the wiring and rearend and mounting everything is the hard part. the cheapest iv herd it done for is like 3000.

 

all i was looking at doing is to wake up my daily driver and maybe get into the mid 14's-high 13's.
