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.

[cory321]

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

[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.

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

[cooters]

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.

[bowtieboy93]

man i hope it has a good warranty lol. i dynoed it at home on a dyno program i have it said a supercharged 502 will overheat but with the right fan and rad combo it should run 170 which is overbut acceptable.mostly this truck will be going to white rock, around town on a cruise and up to ashcroft. it is all open road mostly so over heating is not a factor.and for detonation im not gonna be pushing this motor to the limit. but i will consult my dads friend he is an engine builder and had made some of the sickest stuff out there but i will consult him first.

[bowtieboy93]

according to weiand- run 4 lbs of boost will give u what u need and anything above is certain detonation. i measured it all out drop the motor 2" cut that front crossmember a bit and get a 3" cowl u will have 1" clearance.
