Well, I'm running into the peoblem where I have given my Model A frame a good front sweep to the frame. however, this drastically messes with the simplicity of just going and mounting the motor....as it seems I think (99% sure) that I'll be switching over to an electrical fuel pump. Before i do, I want to get some opinions on which you'd run and why? Electrical,..mechanical?? As it seems, I have been looking into old hot rod mags and have seen a dozen nice motor mounts to get your engine into an A or 32 styled frame, however, with every one of those, you would HAVE to remove the mechanical fuel pump and go electrical.....recommendations for a good solid and quiet electrical one would be cool also. SO!,....if anyone knows a way around dropping an Olds 303 V8 into a swept Model A frame (approx 5-6 inches sweep) and get it to sit low into the frame instead of high (it will obstruct vision!!) feel free ti chime in and flap them gums! Thanks a million guys! Jason Here's the sweep on my frame,..you can see it in my Blog "model A project" www.myspace.com/coaltowncowboy
i'm using the Carter electric pump. i don't know anything about the Holley pumps,but my neighbor Floyd has a whole box full of broken ones...
electric is fine but if your carburated you'll have to in stall a regulater as well carbs only like about 7 lbs presure and most electrics are well above that Al
exactly "which" carter are you guys running? I hopped on ebay and it looks like there are a few on there,.....haven't searched beyond that yet...
Stepping the frame (Zing) like you've done will shorten the wheelbase unless you've lengthened the frame rails in the process. This means the all ready too short Model A engine compartment will require severely recessing the firewall into the cowl to acommodate the length of most or all overhead valve V8s. That early Olds can be easily set into the ch***is if you set it back far enough clear the front crossmember (replacing the Model A crossmember with a smaller gusseted one made from rectangular tube would minimise the set back). The stock front mount can be accomodated with a dropped crossmember made from small size tubing under the front pulley and the stock rear side mounts picked up with ears or a crossmember at the bellhousing. Abandoning the stock seating position would seem to be a prerequisite no matter what course you choose. To use a mechanical fuel pump or not is the least of your concerns at this point.
I've taken all of that into consideration and I guess its one of those things where you have to literally be there to know what I'm dealing with. "replacing the Model A crossmember with a smaller gusseted one made from rectangular tube would minimise the set back" It gives you nothing more than roughly 3-4 inches to play with without the stock crossmember. It's practcally a useless notion, but I have already replaced it for other reasons. "The stock front mount can be accomodated with a dropped crossmember made from small size tubing under the front pulley and the stock rear side mounts picked up with ears or a crossmember at the bellhousing." That's actually not all that far from what I'm working on as an alternate design to accomodate the engine mounting to the frame at this point. However it still would not use the "stock" original motor mount, as there still needs to be a new mount made that will need to incorporate both the bottom motor mounting area AND the second large moor mounts on either side of the engine. The less welds you have on a single piece, especially a motor mouht, the stronger it will be,...and that is what I am aiming to accomplish. "Abandoning the stock seating position would seem to be a prerequisite no matter what course you choose." ....huh?? you even just said that "The stock front mount can be accomodated..." Its not a matter of accomodating the "stock" mount at this point, that's pretty obvious in the way in which the frame is swept and the engine will need to sit in the frame. "To use a mechanical fuel pump or not is the least of your concerns at this point." No,...that is PERCSELY the problem here,....the fuel pump and attached gl*** bowl fuel filter IS MY MAIN concern here. You're missing the point completely. IF you take the time to look and reference some old Hot Rod, Car Craft, etc. magazines articles, ads, etc. then you'll see what I'm talking about. Every single ad, artle, etc. that I have come across illustrates a dropped engine mount, but the stipulation to the said engine mount IS THE MECHANICAL FUEL PUMP! As it is now, the mechanical fuel pump is in my way,.... ...hence my initial post in regards to the question in the first place.
speaking of least of your concerns, block off plates are easy to make but, if you want to use a vintage piece to cover the stock hole the Chevy six's and big blocks are the same as the early Olds...probably lots of others too I had a red Holley pump in my Olds (and later BBC) powered coupe, loud and anoying, but never a failure
Just a suggestion, but you might get a better response if you post a picture. I couldn't find it on your web site and what your discussing is hard to imagine. I'd like to see how you did the crossmember and the "sweep".
by "sweep" I ***ume he is refering to the patented Bleed Sweep on an A frame and you seen one Hurst (or similar) early Olds mount you seen 'em all.. I know it's not trad but, have you considered an in tank pump? would make it a lot quieter
Yes, the sweep I have done is what is commonly known as the "bleed" sweep, though I have seen it done before I ever knew bob did it,...only once or twice had I seen it in pics. Bob's the man though,...amazing stuff comes from his brain!!! As far as a pump, yeah I'm heading out to a swap meet tomorrow and am going to pic up a block off plate, but in regards to an in the tank pum,..I think I'm going to stay away from that, but thanks though either way for the suggestion! I have heard a lot of guy runnng the carter pumps, on other boards also, and only one or two with problems. I have one more trick up my sleeve for a motor mount though before i go hog wild and go electric. I took a look at a 1959 hot Rod mag I have and saw a perfect motor mount that I believe with a little messaging and tweaking of the original idea, I'll have what I need. I just have to figure a very percise way to heat and bend the 1/4" thick plate to put in an offset on each side of the motor mount to get around the fuel pump, then, when all is said and done, that should get me around my problem and i should be good to go on from there.

Aman- here, go to this. You'll have to be member of myspace though. http://blog.myspace.com/index.cfm?f...&MyToken=c405a2fe-d409-40a7-bb9a-6d5be14b10d1 This will give you the specific Blog taht I had started to show what I was doing with it. Its not updated to the motor mount problem yet, but I'm going to do that soon. I have to upload the pics of the motor, mount idea, etc. soon also. Jason
Someone sells a small in line electric fuel pump that's about the size of a fuel filter. I've seen them on quite a few old timey rods and one guy said he bought his at NAPA but that's all the info I have. It was br*** colored and had two wires for elec.hook up and inlet and an outlet. I see them mounted near the original fuel pump location or on a frame rail. I had a Holley pump on my '40 and it was very reliable but noisy. I put a regulator on as suggested above because the Rochester 2g's didn't like the 7+PSI. I ran about 3 PSI. I wish I had more info on this little in line pump,it looked like a nice compact way to go.
Hey guys,...here's a link to the myspace page blog of mine but with new updates to what I'm dealing with on the motor mount issue. I just did a REAL simple photoshop line drawing (sloppy I know but I'd rather be welding and cutting right now!) so I kept it simple. http://blog.myspace.com/index.cfm?f...&MyToken=79103e7d-85e7-4243-bcd5-fa9113ac2c23 Let me know what you think! If you're not a member just register, takes only a minute and then you're done. Then you can rear blogs, etc. Jason
On the way to indy roadrockets show I sprung leaks in 2 stock olds fuel pumps and put a cheap electric one on to get home. It was easy and the car seems to run a little better so I'm gonna leave it.
oh I was there, I had the 50 gmc,...I think I remember spotting your car there,....think we may have met, I'm a good friend of Ace Brown's. Know I met Rocco. yeah we'll see about the pumps,...I keep hearinf fans of both mech and electric!!
