I need sombody to give me an idea on my new configuration.
std. bore 350 (3970010) 9.1:1 CR (with 72cc heads) #416 heads (2.02/1.60 valves 60cc chambers) 110LSA .233/.242 duration .504/.525 lift cam weiand team G single plane intake holley 670 street avenger long tube headers and just for the people wondering 3000 stall stock 700R4(it'll probably explode, planing for a B&M TH400) what ever ring and pinion ratio the stock 4 link 8.5in 10 bolt has and 255/60 15 futura GLS (launched a 2.0 in the T/A on stock TC) |
Why such a low CR?

Moved to the tech section, and shoveled the ****. Keep it on topic please.

What do those heads flow?
|
Bubba, did you mean 416 or 461 heads?
|
I still ask, are you sure it's an 8.5" 10-bolt? They only came in '84-'87 Turbo Regals and '84 Hurst Olds, and '85-'87 442s. If it's the original rear from your Regal, at best it would be a 7.5" rear with 3.08 gears; most likely it's got 2.41s or 2.56s though. If it's not original, then you gotta do some research; find out what it was from, or pull the cover and start counting teeth.

Bubba,
It seems to me that you have a ****ed up combo. Highway gears, medium/big cam, 305 Heads, single plane manifold. Looks like you have some high RPM parts matched with off-idle parts. How did this run in your firebird? Did that have low numeric gears? |

thats what the 305 heads look like. I had them completely redone so they would run higher RPM. the T/A never got to see this set up. the rear gears are getting swapped out soon, thats just a given. I know what I need to do with the rest of the car to work with the motor, right now i'm concerned with draining every last ounce of HP I can get with what I got |

Never seen a G-body with a factory tq. arm setup either. - Justin |
i'll have to look again...i'm pretty sure its an 8.5
|
Is this emissions friendly setup?
If not, maybe drop the LSA down a few degrees. |
emissons what??? lol I've been looking at a few cams I like the voodoo cams for various reasons
|
its telling me 257/338 @ 4k.

And Justin is correct, 99.8% of the G-bodies produced had a regular 4-link rear. Only the '87 Buick GNX got something different- they came with a Watts link setup. |

Where did you get the heads done? See if you can get better flow information from whoever worked on them to help build a better model of the engine. |
