please tell me about how much h.p. gains can be had from the 305 torquer heads with high flow exhaust such as tes or good cat back system. Tech at Jegs says 30to 35 horses. please speculate or affirm.

 

a lot

 

with good gears, torquer 305 heads, lt1 cam and an edelbrock performer intake would i be able to at least smoke a 5.0?

 

it would be a good race just watch out for stick notches there realy fast.

 

Camaro Performers Magazine did a before and after comparison, with a 305 TPI, using World Heads and stock TPI heads. The before numbers were 215hp and 274lb-ft. With the World heads 266hp and 337 lb-ft. So a 51hp and 63lb-ft bolt on increase over stock.

I don't know if the increases would be the same on a TBI because of the peanut cam. But they are a 51hp increase over TPI heads, so they must be WAY better than TBI heads.

 

id say with a good cam you may see that kinda horsepower increase but probably alittle less torque

 

Ok in that test they replaced the cam with a Comp Cams roller camshaft also. Though I could not how much I tried, find out what the specs were on the cam because there was no mention in the article. The 416 TPI/LG4/L69 heads are worth at least 10hp over the TBI heads unported, so I would imagine at least rougly 30hp increase over the stock TBI heads when just bolting on the Torquers.

 

I have the article and I think all they did was convert the 85 TPI to a roller cam. In the test with the stock heads the engine made 215hp and 274 lb-ft which almost exactly what the stock version made. So the roller cam they put in the engine had to come very close to the stock one, if not exactly. Both heads were tested with the same cam because they stated that they were “tested under identical conditions”.

But with the LO3 cam don't think you will see the kind of gains they did. iroc22 I will agree with you though, I also think they will be worth around 30hp increase on a stock LO3.

 

I've heard that you can run 2.02/1.6 valves on the World's
because they have a special design angle to compensate for the
305's small bore.
So who's gonna be the brave soul to try this??
I'm gonna call World first b4 I try anything.

 

I believe you are thinking of the Trick Flow Twisted Wedges, not the World Torquers. I could be wrong however...

 

You're not wrong. In any case, you can run 2.02 valves on the 305 with a .450" or less cam safely as stated by edelbrock.

 

OMG im about to lose my mind if i see any more posts about whether imaginary cars with imaginary mods can beat other imaginary cars

WELL WHAT IF I BOLTED ON A ROCKET TO THE ROOF OF MY CAR WILL I BE ABLE TO BEAT MY FRIEND JOE BLOW!?

 

depends what you use to mount it to the car

 

Forget Edelbrock. If you've ever looked up through the crankshaft valley at 2.02/1.60 on a 305, there's a lot of room. Shrouding wouldnt even become a factor till lifts past .550" in most cases.

Yes JR305, they must have used a very similar cam to a stock one, only in a roller version.

 

would you see performance differences with the bigger valves? i know the 350 heads need to be milled...how much would that cost?

 

Which heads are we talking about being milled?

You would see more airflow with bigger valves resulting in more hp and rev's.

 

i was thinking probably 64cc vortec heads since they are cheap and i hear they perform well

oh yeah in that 325hp 305 buildup they used the vortecs and it made i think 28 more hp than the torquers did....this was a non roller car to...think more than 325 hp could be made on a roller motor?

 

easily, teh lower resistance of a roller motor over a flat tappet means it will make a little more power withthe same cam specs. with "small" cams liek we are using it is only a little, 5-10 at most, but it is still more.

wonder if TBI could be modded to work and make that kinda power for some reason i doubt it....everyone that switches to carb seems to be happy its making me think

 

I think that TBI can at least make the power of a carb (big argument on the Tech/General Engine board ). I hope to run some strong times this summer to prove it.

IMO the people that are switching to carb are happier because they have more experience with it. Learning to burn proms is not easy, I am in the process right now. I have almost no experience with carbs and have to deal with emissions laws so I will be using TBI for the long run.

 

see since im only 17 ive never had to deal with carbs or chip burning so im right inbetween....im thinking about staying TBI because it will be cheaper but ill have to start burning chips or something i guess or the TBI will never work very well...but isnt the ECM different in a 88 since it was the first year? i heard you cant burn chips for my ECM....if thats true im definetly going carb

 

Wow I just turned 18 last week. That's not a good reason for having no experience with anything. How big of a cam are you planning on going with? The ECM is different in 88, but I havent heard that you can't burn chips for it.

The reason carb is so popular isnt because it can make more power (it makes less torque in every case) but because it's easier to tune for more power.
