I have read alot about stall converters, would one b a waste of money or b beneficial?

any help would b appreciated, cheers

If you don't want to spend massive $ on heads (ie roller rockers etc)?

This cam with a 2500rpm histall and 3.54 diff would go nicely. Skim a little off the heads raise compression up to 10:1.
Throw on a Edelbrock performer (dual plane)/650DP carb (squarebore).
Stock fuel pump will be able to fuel it.

Cam dynamics (CRANE) Cheap but does the job well.

HYDRAULIC - Fair idle with lope broad power brand in street engine with minimal modifications. Low valve lift suitable for single stock type springs. BASIC RPM 2100-5000

(use)Street/Strip/(grind number)CD219-52/(part number)/(lifter part no)972803 C35-16 or 99280-16.

Deg. Dur. & .050 Cam Lift Int. Exh 219 219
Deg. Adv. Dur. Int. Exh 290 290
Deg. Lobe Separation 114
Running Clearance -Hot- Int. Exh. .000 .000
Gross Valve Lift Int .505 .505

You'd run a high 13sec to low 14sec 1/4 pass depending on traction. Which is enough poke for the street although you'll get bored as everyone does.

Seeing you are on a budget imo 650 Vac { $350 Hume performance Sydney} Funnel web inlet {07} 4122 1636 or TFC (03) 9362 0266 from $665 tongues etc can be purchased to increase torque.
Edit ::Check out Edelbrock there inlets maybe better for lower rpm torque..
Cam ? check Crane cams but nothing over 220 @50 lift, 280 adv imo..Good valve springs are a must.The falcrom on the rockers wear so check there.Raising compression helps too especially when a cam is installed..Check that your distributor is working correctly, the advance/ counterweight springs often become weak or loose on old engines....Check advance curve... hth..

The only issue I'd have with a Vac sec carb is the vacuum is severely decreased in a reasonably cammed engine such as the cam I suggested. So the secondaries will open later than they should. I guess lighter springs could be added?

The funnel web manifold would be pretty useless unless stock 302 wants to spin a stock bottomend over 6500rpm. Which means new springs/stud mount roller rockers/studs in the heads etc. Lots of $ to do that. Trust me I have big $ 2V heads.

In my engine I can't even run vacuum advance as ;

the distributor won't advance. I have to run mechanical advance. Vacuum kick down on the auto doesn't work as it should.
Chance of vacuum secondaries working as they should zero.

Although my engines very different spec to what I've suggested for Stock XB.

Cam I suggested should run with about 26-28deg total advance. Maybe a little more but not much.

A mate of mine is running the cam below the one I've suggested. He runs a 650DP. His cam has only 480or so thou lift but not over 500thou. His XC panelvan running a 3000rpm histall/3.7 rearend behind a 351 runs 14.195 at about 93mph.

Although I am quite interested to see what other people would suggest also.

A good 650DP can be had for about $200-250 depending on type. Manifold? About $150-200 also no need for new unless you have $ to waste.

change crank and rods to a 351 ... best bang for buck you will get

TTNOS8 · 05-22-2003, 03:51

agree with xa-.

flick through the trading post, find a 351 crank and rods for $~200 and whack 'em in! :)

forget the stally put a manual in it you wont regret it

StockXB · 05-22-2003, 15:55

thanks alot guys for ur input i appreciate it. i think i will go the 351 crank and rods, i read the thread about changing the piston type and using the 302 rods, but i think i might stay with the 351 rods to avoid any trouble. Elderbrok performer manifold and a 650D/P and a cam should keep me out of trouble for a while.
cheers

thinking about toploader, he he. you guys r a bad influence

ebxr8240 · 05-22-2003, 15:57

Ahh I thought 351 there so cam choice is even more critical on a 302c.Depends what you want either quick street or more ballsy but at a pita "at times". Yes the bigger cam will requre d/p but it depends what you want from the engine etc..I'm not keen on d/p's with auto's either in std form anyway, but thats just my opinion.. Yes a 351 conversion is streets ahead...

StockXB · 05-22-2003, 16:09

well id like quick street but i dont want to ring its neck all the time, bit more bottom end would b nice. would u recommend changing the pistons and using the 302 rods or go just with the 351 setup? so cam is even more critical because im changing it from a 302 to 351, wot cam would u recommed?
