502

[bowtieboy93]

just wondering if anyone knows if a 502 with a weind 6-71 supercharger with 2 holley 650's and a 1 1/2 inch air cleaner would fit under the hood of a '69 or would i need to put in a 2 inch cowl induction hood? drop motor mounts or whatever as long as i know if it will fit or not.thx

I have a very good feeling that this guy would know, bskylerj is his moniker on this site.

you should check out some of his post's on his truck, it's a big block with a super charger, well over 700HP I think now.

here's one of his post's, it's pretty cool stuff.

uuhhh.............................. no, not quite.
























maybe if your hood has a 6-8" cowl.

[cooters]

need more than a cowl hood!

[bowtieboy93]

i somewhat measured its like a 2 1/2 3 inch cowl the aircleaner i have now is like 6 inches tall and i had like 5 inches to the bottom of the hood

[bowtieboy93]

i m not going with as big of a supercharger and no carb spacer plates and no scoop i have heard it can be done with some slight motor mount dropping added

[trkklr77]

uuhh thats a 6-71 super. the top plates are all about the same thickness. 1-1/8 to 1-1/2" thick.

some motor drop, you will need to gut your engine bay, fab a skiin cross and make all new mounts about 6-7 lower in the frame.

if you switch to a 144-177 weiand or b&m single carb it will fit with a small 2-3" cowl, they are only half as tall as a 6-71.

oh sweet thats the best i can find on weind crappy website was that. i priced out a 502 and everything else (with supercharger) and it came out to $14,000 starting out with a ZZ502 which is 502 HP and 567 LB Ft of tq. thx

[eedgell]

Yah, I know a guy that put a small weind in 70 4x4, and it stuck out of the hood 3inch or so on a small block.

[bowtieboy93]

thats not bad im gonna try and find the thinest carb that will handle the power it needs to help produce.

just build a 572 from a 454 and save time and money. the rotating assembly can be had for under 2 grand. just a suggestion. i like stroked big blocks. i have a stroked bbf ( 557ci ) in a 4000 lb car that runs consistent 11 sec passes. give me torque and you can have horsepower.

[cory321]

I think the compression on the zz502 may be too high for a supercharger.Not sure

Edelbrock just came out with a small blower, looks good. As far as lowering the motor, my big block is only 1/2 inch from the x member now and major cutting would be needed to drop it more than 1 inch

[bowtieboy93]

i went to edelbrocks site and no success i didnt find a thing on prices on them and it didnt say applications and it was only from stock motors. it said "will give u up to 500 hp and 557 lb ft of tq which the motor im starting with already has more than that

You have a problem, to make boost on a 502 without excesive intake air temp requires a bigger blower than a 6 71 but you dont want it sticking up. You will not get the best of both worlds. I believe that what you are trying to do is not realistic.

[bowtieboy93]

i have seen a blown 502 done with a weiand blower i know for sure it waasnt bigger than a 6-71 and that car ran low 11's

[cooters]

a stock 502/502 should run in the 11s without a blower if the car doesnt weigh 4500 lbs. You need to figure out what your goal is for the motor and then come up with a combo that works. Spinning a little blower to make 5 lbs of boost on a 502 will heat the air up alot and detonation and general undrivability on the street will occur.
