so, found a 8cm flathead and a english ford gearbox alredy set up for a flatty, was a 53 engine and had the wrong pumps - not 51 wrong pan - 3 rib stuck distributor stock carb stock intake 3 7/4 crank 8cm ford heads twin pulleys no starter heads off wrong flywheel wrong clutch so put up a wanted advert for 390 holley 4 barra intake short hi torque starter aftermarket electrastical dizzy 4'' crankshaft s10 tremec t5 flathead to t5 adaptor and clutch sanderson headers - would you beleive, someone done took it oot a running driving car to fit a sbc, ?? hmm mercury heads nice merc cvrank all done with fuel in the bowls so anyplops, before i run it just got a fuel pressure regulator - question what psi does the 390 want to see? 6 ilb? want to buy a 1310 outy clip th350 chevby s10 slip yoke can you assure me please that gm is 26 spline and ford 25 ? do i need a long slip yoke in that tail or does it not matter also, its elastic speedo - is the hall effect pickup the same item as the later ones do they come with a tail. oh and lastly, there is no oil filtration at all on this, is that bad?
No oil filter on my 8BA. May I suggest adding a PCV system? It made a huge difference on mine. I am looking forward to your build, you are doing the research!
I like oil filters. The original bypass system is fine, but I like them mounted on the fire wall instead of cluttering up the head. just my op. Good for you, nice score !
Pretty straight forward on an 8ba. Remove the road draft tube and insert a grommet that a PCV valve fits into. Use a valve from an engine that is about the same cubic inch displacement as your flathead. I used one from a 231 Buick. Run a hose from the valve to the vacuum port on the manifold and call it a day.
My 390 fuel pressure is set at 3 1/2 psi on my 8BA. You didn't say what car you're working on but, in a 40 Ford the 390 accelerator linkage works best with carburetor installed backwards so carb linkage is on passenger side.
aha! talking about the carb are those two barbs for dual fuel input? theis is going to be right hand drive, i have the stock rhd go pedal and rods maybe it will work -the thing came with a hydraulic clutch set up but i think it maybe easier as it has a chevy fork to go cable and use the stock clutch pedal to pull again there 'might' have been a go to clutch cable for length lhd, hmmm
ooh, while i am on is there a 'popular' consensus of opinion as to where the middle of the output shaft wants to sit - in relation 'say' to the line across the top of the rails .
ahh, so the real question is -at what fuel pressure does the pressurised fuel bend the float retaining tab?
anyone in the world make right hand drive headers to fit 35-40 but right hand drive with stock 37 steering?
ANSWER: 7 psi is recommended as the maximum fuel pressure for Holley carb. Look here. What fuel pressure should I run with my new carb? (summitracing.com)
As @51504bat posted, it is easy on an 8BA that still has the internal pipe under the intake manifold for the raod draft tube. I bought a PCV off the Ford barn that was made to fit the intake draft tube. The hard part was a vacuum source on my application. I took it from above my blower in the carb base. The air enters through a breather on the rear of the intake manifold. Prior to this I had oil dripping from the bottom of my pan and that all too familiar flathead stink. After install, no leaks at all and no smells other than 92 octane in the morning.
