he wants new heads,he has $5000 to do it ...or a little more
but he is not worried about it
what's the AFB's you suggest ?
he is kinda in love with a double q-jet setup i guess just for the look

 

A suggestion..

I recommend 'FBird-88's Vortec build! :thumbup:

 

are the vortec heads the ones that make too much power ?

 

No, I meant what I said.

Going to the 'net for information is a somewhat risky proposition. One has to lurk and get a feel for the smart guys vs the others out there.

FBird-88 has a basic build that he recommends that requires minimum machine work, has all the right parts that work as a whole, and leaves one with $$$ in their wallet after the build.

He has spoken in the past that this build dynos at around 400 HP.

I took my just completed FBird-88 out on the road this evening and it is so much more than what I had, it is "Scary-cool".

The very first thing I noticed was how little gas pedal it takes to go fast. Rapping the throttle in the driveway and the motor tachs FAST!

This motor has an urgency about it and a ton of torque in spite of the cam grind.

I cannot say too many nice things about this Fbird-88 and his build.

If you did not give this build the consideration it deserves, well, THAT is what I would call a "Joke".

 

i replied wrong window ..i meant it for another thread
yes im watching his setup and the other thread ...
wow...maybe the vortec has something to do with it ?

 

here its only 93-95 and 97 octane fuel
why a NO NO for the double 4 barrel setup ?
thanks

 

Oh im sorry,when i meant QJET it can be any fourbarrel carb !
what's best ASV or AFB ? Double AFB ?
thanks fbird

 

Good 1 Fbird, "Diapers" . You don't think he'll soil himself do you? :thumbup:

 

We have built some 355's with Vortec heads that have been worked with seat cutters and a bowl howg, deshrouding and cut for 64 CC's screw in studs hyd. cam. The block was zero decked we use 6 inch rods in our builds to lighten up the pistons.

The last build with a single HP 600 carb made 432 horse and 460 ish on the torque.

Our circle track engines we use Ford flat tappet cams (solid) heads cut to 59CC's which we shoot for 11:01 and we are restrcited to a 600HP carb and we have seen 515 on the dyno and 485 on the torque.

The money you will save on buying 2 carbs and an intake manifold you put into a good lower end.

Good luck with your build Carl

 

Forget the dual carbs. Much more trouble and cost and no hp gain. All he needs is a Performer RPM intake and a holley 3310 750cfm with vacuum secondarys. Spend any extra money on a 383 stroker kit and/or better heads.

What year nova?

Easy to build 400hp. Plus, a stock bottom end will hold that with no problems Especially with a street car, that will not be at max power for long durations.

What gear and transmission is he planning to use?

Go with aftermarket or vortec heads (160 to 180cc) and a cam with around 230 degrees duration at 0.050". Edelbrock, Dart, AFR are good aftermarket heads to consider.

Hyper pistons with 9.5 to 10:1cr should be about right.

Maybe upgrade to some better rod bolts.

A 400hp 350 cid will need at least a 2800 stall and 3.73 gear.

A 400hp 383 cid will need at least a 2400 stall and a 3.55 gear.

You can build 400hp with a set of stock heads but would take a much bigger cam (240-250 degrees duration), 10.5:1 cr, and would require a 3000 stall and 4.11 gears.

 

My vote is for cubes. You can stick your stock heads on there and replace them later while the motor is in the car, but you can't swap out the bottom once you get it in place! Cubes are king on the street. They give you a nice, wide power band to play with and are more forgiving with weight/tall gears.

Good luck whatever you decide-

thanks for your suggestions
its not my car actually
its neither a nova ...
its a 1963 Acadian beaumont coupe (same as chevy II)

he wants to stick to that car ..because its 1 of 1500 made.-
i don't like the car at all but he wants max power out of it
..what's the cubes,killerformula ???
thanks

 

where do I find the exact specs and parts needed to build an F-bird Vortech... since my motor is on the stand AGAIN!!! i mnay as well build the damn thing up from scratch.. assuming the machine shop doesnt deem the Block as Dead....

build recommended by F'Bird-88

a basic 350ci SBC short block with flat top pistons
+ 062 or 906 GM vortec heads, shaved 45 thou.
.015 steel shim headgasket (felpro)
Isky #205D valves springs minus the inner damper
Stock OEM vortec retainers, seals locks and rocker arms
Isky #201278 camshaft 278-278 .450" .450" lift 234-234@.050" 106° LSA
Edelbrock Performer RPM Manifold and 750cfm 4bbl carb
1-5/8" headers 2.5" dual exhaust.
This combo makes more power and torque than the Edelbrock RPM cam will make without needing vortec cylinder head machining modifications to accomodate the .488"-.510" valve lift of the Edelbrock RPM camshaft.
Should use a 10" high stall torque converter and 3.73 to 4.10 rear gearing for best results. (same as the rpm cam needs)
Isky #201288 will make even more top end power all with just .450" valve lift.
Degree the cam in on a 102°-103° intake C/L for best results.

 

I would not go with an Eddelbroke, Q-jets when working properyly are an excelent carb.

Hey update here !!!!!!
The rod will be old 50's chevy pickup
they guy,that is still obsessed with the double carb setup

Edelbrock 2102 ?
Edelbrock 2103 ?

Edelbrock heads :
Performer RPM - 607119 angle plug polished ?
Performer RPM - 607319 straight plug polished ?

And a set of 1.6 rocker rollers

which one do you recommend?
thanks !!!
