Re: Buying a flathead
The Rolling Bones Boys are mostly using a T5 trans with a 5th gear overdrive.

Re: Buying a flathead
If you have no parts from various years on hand, having to buy piece by piece what you will need to make a 49-53 engine could be expensive and frustrating. I will say this, even a decent running stock 85 will run plenty fast enough to kill you. A 36 or 37 engine would be the easiest to fit with what you have ( considering intake, exhaust manifolds, fan, dist. motor mounts and so on). Next thing is the rear end ratio, if its a 4:11 85 or 100 hp will not make a lot of difference cause it will be screaming at even 65 mph. A set of brake floaters IMHO would be an excellent way to upgrade the brakes, they sure work well on my stuff. If you have a 3:78 rear gear, a 100 hrs 46-8 would propel you well.

Re: Buying a flathead
Not sure if this pic works I have photobucket, a bit unsure how to use it.
I should clarify my " cruising speeds" I would expect to drive on the freeway 65mph. 80-85 would be nice for passing if I want to. 95% of the time I would be in the city going 25mph. Also from a red light if I wanted to spin the tires I'd like to,just for show( not much fun if people want you to light them up,but all I have is to limp away from the line sputtering lol). |

Re: Buying a flathead
I would vote for a T5 with a low rear end, like the 4.11. That combination should meet your stated goals.

Re: Buying a flathead
No one has mentioned the major surgery required to install a t-5. It involves replacing the complete center section of the frame. Open drive is also a lot of surgery and modification as well. Consider an alternative that works very well is adding a Mitchell OD for $2,500 with the stock drive train. You get the top speed you are looking for and the only modification is replacing the drive shaft with the OD/driveshaft provided by Mitchell. I'd also add front disc brakes and rear lincoln bendix style brakes. I've done the mitchell/discs/bendix to a 36 and 41 woodie. They cruise the interstate effortlessly. Some models require some cutting of the trunk area for the Mitchell. My woodies did not require any mods. The mitchell/discs/bendix is completely reversible as well if that matter to you. I updated my 36 steering box to a 38 as well with little mods required.
You would do well to find a 36+ flathead with insert bearings. If you want you can add 34 style heads for a more authentic look. I didn't on my 36 and only early Ford toadies can tell. I wouldn't call any stock flathead high performance.

Re: Buying a flathead
Attachment 303887Modern 5 speed transmission (with overdrive) often used behind flathead engines. T5 setting in a 34 frame, one with the Chevy gearshift location and the other with the Ford gearshift location.

Re: Buying a flathead
The Tremec T5 transmission can now be set up for closed drive but there is also a T170 RTS 3-speed with a 4th position overdrive made by Tremec for mid 80s Ford Pickups and it can be set up with a closed drive too for the old cars plus the gear shift is nearly in the same position as the old Ford 3-speed. All this stuff requires adapters but it is available if you know where to find it all.
There are still French made engine blocks available from San Fransisco Flathead or So Cal Speed Shop (north). These have the 59 series type rear bell but are set up internally like an 8BA (cooling system). I believe the threaded bores are mostlly Unified Thread like old US non metric but there may be some exceptions. There is a techno site with info on them. They are new or like new manufactured from the 60s up through around 1990 for French military trucks but the price is like new too. The old 59 series blocks are getting harder to find so at least there is an alternative. They were only line manufactured from 1945 through 1948 while the 8BA was manufactured from 1948 through 1953 (1954 in Canada) so they are still relatively plentiful. The 8BA types just take a few more parts & mods to make them fit the early V8 or 4-banger cars. The easiest, in my opinion, would be a hopped up 59 series V8 and the old 1939 thru 1950 top shift Ford 3-speed. The 34 V8 rear axle is useable but I'd look for a later one that stays in the 35 through 41 width range and mate it up with a Mitchel OD torque tube and use the radius rods that work best for it and the axle. This is just about ease of assembly and fit. There are so many other ways you can go but this might be the most simple way that I can think of with the least amount of alterations from stock. Others may think differently and good parts harder to find. This is a good old traditional hot rod way of doing things with the exception of the Mitchel overdrive but I think the overdrive is worth getting for the best off the line and highway performance. |

Re: Buying a flathead
I've always wondered how a mitchell OD would handle a burnout? I don't think I'll try with mine. I'm sure it hold up, but sidestepping that clutch is hard on transmissions and rearends.

Re: Buying a flathead
Off line, the Mitchel would not have the planetary engaged yet but I don't know how well the shafting or the old transmission would hold up either. There has been discussion about the Mitchel box and the rear floor clearance on the 33/34 cars too. Although more complicated, the T5 or the T170 would likely be the stronger for an application where you could dump the clutch. Back in the hey day of hot rodding, the clutch dumpers would look for a LaSalle 3-speed transmission to put behind their hopped up V8 mills. They would get tired of replacing the old Ford 3-speeds and I guess the LaSalle unit could take a lot more punishment. I imagine they still sheared axle keys or broke the axles though.
All are considerations for an update build of a 1934 Ford. Easy isn't always better but it depends on whether you want to thrash it real hard or not. A 1949 Olds 303 rocket motor with a narrow 9-inch Ford axle & open drive would be somewhat traditional ( mid to late 50s) but it's also a lot more work. Just to Add: I forgot to mention the axle updates that can be had from The Hot Rod Works up in Idaho. Some of their mods will solve the old axle problems. A person might be able to thrash the rear end a bit more with their mods. Last edited by rotorwrench; 02-08-2017 at 01:51 PM. |

Re: Buying a flathead
It's funny what age and spending substantial $ on a car will do to people. I cannot force myself to dump the clutch on anything I own these days. I have an O/T '67 Corvette that is essentially a new car, (rebuilt engine, trans and rear end completely gone through, new u-joints, etc., etc., etc.) and I can't bring myself to do a "spirited start" in it. I have tried several times, but I just can't bring myself to do it. Back when I was 18, it was noo problem. I was a lot better at crawling under it and changing things, though. Plus, parts were easy to come by and a lot cheaper.
