Can anybody suggest how to get more hp??

The blocks are the same for a 302/331/347. The difference is in the bore size (.030 over stock bore). The critical dimensions come in with the longer stroke crank and connecting rod lengths and piston compression heights. The 351W is a different block from the 302 but is the same architecture (designe). The stroker 351's use a stock block as well to build strokers. Aftermarket blocks (both 302s' and 351s') Allow you to go even bigger...363 CID fore the 302s' and upwards of 440CID for the 351...

 

Yes sir,caught that one already...

So I guess the way im gonna go and should have gone is 351

 

My 289 loves 8* base...34* total. Anything more it falls on its face, but mpg does go up a little...but nothing to write home about. All engines have their own personally...you just got to take time to know them (no pun intended). What works for me may might not work for you.

 

NOT fast enough??? I think you need to get that car to the track so we can see what you consider not fast enough.
I consider my car plenty fast enough for me on the street. You should be just as fast and likely faster than mine if your set up decent.
What are you comparing your car to??
I've got a fair bit of experience in different vehicles to compare mine to. Dont think I would want much more for a street car.
You may just be getting use to your car and the way it performs so it doesnt feel quite as fast anymore.
Your set up certainly shouldnt be a slouch.

 

I tottally agree with you.since its just a daily driver and I barely even get on it once or twice a month im getting used to it already,people say with my setup I should be running 12's people say thats pretty fast for carb
What do you think?

 

I'd say your in the ballpark but ya never know till you actually run it down the track. Its a whole different deal trying to get max performance out of the car and yourself for an entire 1/4 mile.
I'm well overdue to get my car to the track and get a slice of humble pie. LOL. Mine is a pretty mild build though so I dont expect too much out of it. Like I said I cant see needing anymore for the street.
A 12 second street car is very respectable. I'd be happy with a low 13 for myself.
If you want to go faster and start the transition to more of a track car than street car you might not be very happy with its street manners.
My first Mav was great to race but on the street it was a constant battle. Trans temp, engine temp, interior temps,noise,fuel..... I'm real happy with the car I have now. Has good manners.

 

Tru that. I have a app on my phone that does dyno test (5.99 why not try it) and it clocked me in at 15 secs cause it took bout 3 1/2 secs to get out of the 60ft (only cause I was setting it up and firts try) but if I can get the launch right, im pretty sure I can get in the 12's

 

1. proform center body for holley carb. gets about 20-25hps when dialed in
2. Electric fan setup
3. underdrive pullies
4. K&N air filter
5. you have roller rockers right?

 

Very true! I enjoyed driving my GTO more when it was a low 14-high 13 second car. When it dipped into the low 12's high 11's it was a nasty, ill mannered car on the street. Still fun mind you but not enjoyable. As much as I would like to see some blazing time slips with the Grabber, I need to consider how often I will actually take it to the track.

 

Got the electric fan,k&n filter and roller rockers,and all I have is alt on a belt so it shouldnt be to bad

 

Then there's no point for underdrive pullies. Do you have a link for the model of 600cfm carb your running? Edelbrock carbs LOVE vacuum and pulse in the intake. An Edelbrock carb on a single torker intake is costing you hps and response. With this build putting an air gap on this beast will awaken it. Trust me if you put a proform holley 650 center section with air gap intake on the engine will roar! . Torkers work best with large cams, displacement, and head flow. Even with an ideal built they only edge out the air gap at high rpm while costing tons of power on the low end. My friend's maverick had ported 351w heads, large cam, with a torker II. After swapping in the air gap the motor felt like it had awaken from a coma.

 

What RPM range is the cam-intake set up designed for? Just wondering if you have a motor built for top end power more than low end torque. If it feels a little soggy down low then around 3500+ RPM it really starts to come alive the thing might not feel fast to someone used to instant off idle neck snapping torque.

Mine is like that. Even with the 5-Speed and 3.70s in second gear if I punch it below 3000 it takes a little time to build up steam..... But be going along in 3rd at 4000 RPM and punch it!!! It can instantly fling a Super Big GULP clear into the back seat. Ask me how I know

Oh and I think my car is the one flynbrd is talking about The Air gap made it considerably more responsive below 3000 with no loss up to over 6000. It's still a little squishy down low though....

 

I got the torker-II package cause it 2 steps higher than the air-gap. cam and intake are the same and when I have the heads too the rpm range is from 3500-7500+ now im not gonna be revving it that close to that rpm but im guessing the air-gap is better from a dig and torker-II at a launch or with a higher stall (which ill be getting later)


This is the chart that is shows it

fool with the timing,index your sprk plugs ,experiment with jets in the carb.

 

Could you be more specific about the specs on teh power package you have? I cant find a torker 2 power package. I found one with a performer rpm intake , which is a great intake!

I have heard afr 185's make more power than the Edelbrock heads, hands down.
