Hey there, is there someone you guys can point me to to modify a flathead intake to accept my 471 blower. I know a guy can buy a new manifold but i dont have an extra $700. Thanks in advance Posted using the Full Custom H.A.M.B. App!
Just use. 2x2 fenton and one of those ebay plates? Open on two small ends and closed in the middle between the openings? Posted using the Full Custom H.A.M.B. App!

Contact our friend Roseville carl http://www.jalopyjournal.com/forum/member.php?u=70948 He is useing a stock type intake for his and also made an ldler bracket to work with the gen mount ,, Beth
Check this out... Im not sure how he modified his intake. But a 4-71 isnt to much different in size. http://www.jalopyjournal.com/forum/showthread.php?t=862569
Here's a couple pics of Carls setup, and the link to his build http://www.jalopyjournal.com/forum/showthread.php?t=436556,, Tim Jones
find a 4bbl intaake. trace the bottom of the blower and transfer the carb bolt partern to the template. make sure the blower is in the correct position. done. http://www.jalopyjournal.com/forum/showthread.php?t=124409
If you are just bolting an adapter plate to the intake, beware that some intakes had tilted bosses for the carbs. Maybe that's why guys like the Fenton?
This is what I did, A Canadian 2bbl intake. Milled off the top and welded this plate to it...That extra weld was an attempt at making a o-ring groove A Weiand 144 Made my own 3 carb intake
From what ive read it is very hard to get the measurements and squareness correct when trying to do a conversion Posted using the Full Custom H.A.M.B. App!
Lukes machine in canada looks like the best deal ive found Posted using the Full Custom H.A.M.B. App!
$625 canadian. I dont wanna screw up an intake and mount plate and be out that money. Ive seen posts on doing it but talked to a guy that sells flathead blower intakes and he said its a big gamble doing it the diy way. He said side to side and front to back dimensions are critical for pulley alignment and belt life. Im thinking a couple hundred dollar intake and a hundred dollar pre made plate and the shit to make my welder do aluminum, never mind my time, I'm better off buying one. Just me tho Posted using the Full Custom H.A.M.B. App!
smart thinking there 1931Modela. Flathead's aren't cheap. Blown flatheads are worse! at the end of the day the cost of an intake to make sure the blower is where it's mean to be is at worst 2x the cost of a 2x2 or 3x2 intake. You will end up having a fair wack of $$ in the motor by the time your finished and I don't think the cost of the intake will be what weigh's heavy on your mind. I endorse having a go yourself if you have the tools and the knowledge, but also realise that sometimes spending $ to get the right part actually saves you time and $ down the track. Really depends on a guys situation. Good luck with it, its a fun ride, both building the motor and also once its done.
I was lucky enough to get mine on e-pay years ago. The Mitchell intakes are getting rare, I'm not sure if they're even still in production.
