how much hp and torque..

[Irish_Alley]

and get everything to be on the same power band. or they wont work well together

Well I mean the vortec v3 and small roots blowers can be bolted on as long as the compression ratio is low and the motor is fresh and boost is kept low like 5 or 6psi I just finished a blower motor for my camaro and its specificly built for the blower loser piston to bore clearances blower cam blower pistons ect it should make around 800hp at 7500rpm on race gas with 16%a over drive

[Irish_Alley]

yes you need blower rotating assembly if you want her to last. even 5-6 psi is what like essentially 15-20
"Fast, Cheap and Reliable" you can only choose 2

got a l67 its only 240 hp and 280 tq. its NA sister is 200 hp 240 tq

15-20?

having a sc engine and a na engine. its not just throw it on and go you have to thing the more air you have going in the more that hast to leave. so you need to start with exhaust and then work on the intake. stock i think the sb was putting out about 200 with just pertty much adding a cam and headers your not going to gain close to 300 to started you need better heads than cast iron heads. think about it like this if you just add a bigger air filter what will that gain when its still being sucked threw a straw.

i guess its a now brainer to go with some heads then.... whats recommended vortec head or go straight to aluminum heads.... so you dont think im at the 300 hp mark with what i have so far...

what do you mean by l67 and NA sister?

If you are on a budget, the Vortec's are hard to beat. Summit has their own version, ready to go that can handle .520 lift, for 620.00.

hey there... i was wondering how much torque and HP my engine is putting out... its a fresh engine but with rebuilt 30 over.. stock heads cam 204 intake 214 exhaust at .05 duration... performer intake.. 650 edelbrock carb, headers and electric fan... any ideas on HP and torque outputs... i was thinking about installing vortec heads.. but its only a daily driver so i dont think its really worth... what do you guys think? thanks for the input..
by the way any ideas for more torque?

Based on 1.94" intake, 1.5" exhaust, non-ported stock heads with 9.5:1 compression, fed 650 CFM through a dual plane Performer, and estimating your cam profile, you probably are generating somewhere around 300 hp and 425 lb-ft. 

With your cam/carb combination, migrating to 195 heads with 2.02" intake, 1.6" exhaust and 76cc chambers (~10.5:1) could net an additional 60 - 70 hp and 40 - 50 lb-ft, shifted ~1,000 RPM higher.  Of course, this is a WAG with plenty of assumed variables.

The cam/carb combination you've chosen beg higher flowing heads, but 195cc is probably about the limit.  Outside of forced induction, less restricted heads will provide a significant improvement.  However, boosting compression may require higher octane fuel. 

Aluminum heads are more tolerant of compression increases w/o incurring detonation than are iron heads.  But, iron heads are less expensive and may provide improved service life.

Keep in mind to, there is no difference in power between aluminum and cast iron heads with the same flow numbers. There is weight loss and lower temperatures with aluminum though. Vortec heads are cost affective and flow enough to support 400+ hp with a little work, but these heads are better for torque with the 170cc runners and 1.94/1.5 valves.

What are we talking about when you say rotating assembly ?

[gildardo01]

lets say i install some vortec heads what kind of HP and torque will i be looking at now... think 350 hp and 450lb tq would be possible then... ?

[gildardo01]

What are we talking about when you say rotating assembly ?

rotating assembly... means the bottom end in an engine... pistons, rods, and crank...

what do you mean by l67 and NA sister?

L67 is chevys 3800 super charged engine, NA is naturaly aspirated

15-20?

when you take into the natural vacuum of the engine if you want to get to 6psi you have to not only do 6+ but the counter the natural vacuum
