I thought that to, it may be but What threw me off is the bottom doesen't look all big and open on the bottom. like these. How would you run a bypass valve/blow off to avoid serge with something like this?
If I remember right a 6v-71 is a littlle shorter than a 6-71 but the rotors are the same dia..I would say that if you can use it as is then it's worth the $350..
the one picture looks like the bottom is offset..probably just the angle of the pic..tried contacting the seller and find out if it has been setup for gasoline yet...difference in rotor clearance...cool setup for a belt dive though.. on a side note, the blower bug is a nasty lil sucker when it does bite...been there...got the t-shirt
Thats funny. Thats the problem, is that the owner of it does not know anything about it. He just said it came off a "gulp" rat rod. Said it was running. but who knows. other than the carb, the pulley drive set up, which i'll have to make, do they make an adapter to/intake. of is that something else for me to make. o yea whats needed for a bypass or blow off to prevent surge?
the 6v-71 has the bolts canted. It could be a 6-53. I didn't notice it was lacking the lower bolt flange.
I think your right in it could be a 6v-53...I went and dug a pic up of the 6v-71 I have and the ribing and end covers are different..I wonder how much cubes a 6v-53 could support? Maybe be about right for a flathead...
the nomenclature for gmc blowers is Number of cylinders and cubic inches per cylinder. so a 6-71 was a 427 and a 6-53 was a 318. I've seen 6-53's on 292 sixes and 283 small blocks. You could use it on a larger motor if your not trying to push 7lbs of boost.
Its a 71 series with a pruned case, the mounting lip has been pruned off, good deal if it turns, have it checked
A 671 has 6 mounting bolts where the carb plate is. 471 has 4 mounting bolt holes. It looks like a pruned 471 like mine.
the flange to support it when it was used in its original planned location on its side hanging on a GMC engine most likely in some large truck. I think its a 4-71 as well but maybe a gear reduction blower with 2 sets of gears stacked on the back end and thats why it still has its stock rear cover and looks funky. pictures are crappy to. does anyone currently cast a 4-71 intake theese days?
If they do I have a need for 2 of them.............. All I can find is one's for a 6 and an adapter plate.
Small world. I bought that thing this month when it was relisted on craigslist with the same picture.
re: AWWWWW and "small world". This is a reminder that sometimes while you're involved in research and hemming and hawing over a purchase, it will get bought by someone with less trepidation. I bought a nice HAMB-friendly ride a couple of years ago. The seller took my offer because another guy he had 'on the hook' was asking dozens of questions over and over and requesting photos of nearly every square inch of the car. I looked at the posted pics....talked to the owner...made him a cash offer, and procured the car, while the other "buyer" was still vacillating over "should I or shouldn't I" dj
