    Engine Cooling problem

    Not unless the impeller is not connected to the shaft. The stock water pump normally works quite well. Corrosion can cause various cooling issues including blocked passages. Was there any sign of rust in the fluid when you replaced the radiator? Also did you use a 50% (or less)...

    Engine Cooling problem

    Have you verified timing? If it is retarded or advanced too far it will run hot.

    1966 mustang 289 Balance mystery

    Yes it should be 28oz imbalance. I doubt that the crank has been swapped out for a newer 5.0 as it (the 5.0) is designed to use a 1 piece crank seal. I don't think one can be used in the early block that you have.

    1966 mustang 289 Balance mystery

    There are no stampings used that would indicate weight. If you can find a casting # it might help to identify the year. Front and rear photos may be compared to those found on the web. If you are going to buy parts and you are sure you have a 289, get them for 28oz imbalance. Are you sure...

    1966 mustang 289 Balance mystery

    Valid point . . . . . Since it was not mentioned, all small block Fords from their introduction in the early 60's until about 1981 have a 28oz imbalance. From then on the 351w retained the 28 ounce but the 303 went to 50oz imbalance. From then on the 351w retained the 28 ounce but the 302 went...

    65 Mustang leaking trans fluid

    I suppose that a converter plug could be loose if it has one, but as far as replacing the seal by moving the tranny backwards it isn't going to be the least bit easy. Remember that the converter has to come down before anything else can be done. The tranny can't go back that far without...

    65 Mustang leaking trans fluid

    Since you verified that it is indeed ATF then it is most likely the seal at the front of the transmission that seals the torque converter snout to the transmission. Typically one replaces it when the have the motor out as an insurance policy against leaks. The seal is the small shiny area...

    '66 Mustang backup light wiring, under dash

    Have you looked for connections on the engine side of the fire wall right behind the motor? Seems to be that might be where they are.

    small block 427, what heads should I run

    Its hard to beat a canted valve head.

    small block 427, what heads should I run

    LIFT is not the cam spec that matters . . . . The valve is closest to the piston in the cam overlap area when the exhaust valve is just closing and the in intake valve is just opening. This occurs within a 20* window when the piston is near the top in the non-compression stroke. This spec is...

    Need carburetor and distributor advice for 1965 6 cylinder 200 ci engine

    Holley used to sell a stock type aftermarket replacement (Model 1940?) that was a cheap bolt on affair and was compatible with the Load-o-matic. It was nice, reasonably cheap and functioned well on a stock motor and could be found at your local auto parts store. I don't know if they make such...

    small block 427, what heads should I run

    TFS used to recommend different pistons on the old twisted wedge versions. Although I have not personally messed with the 11R heads I currently run 15* angle in line valve Victor Sr heads (they require a special piston or piston work) so I added the "?" mark after the statement since I'm not...

    small block 427, what heads should I run

    Thank You FD--Yeah, I missed it . . . . The RPM intake and 750 carb would be on par with the rest of the build--a powerful street motor combination that would be enough to satisfy most drivers. The design rpm range of the intake ON A 351CI motor is 1500-6500. The larger 427CI motor ( which is...

    small block 427, what heads should I run

    As is, that's a fairly decent power combo for the street. Unfortunately the parts mentioned are probably near their max. I for one have never had issues getting decent power/rpm out of windsor strokers. Your cam is really shy on lift and I can see how it is very limited by the valve train...

    Speedometer gear

    Slowing the speedo down will take more teeth on the gear at the end of the cable. My rule of thumb is that 1 tooth is around 2 1/2 MPH@55mph so a gear with 3 more teeth should have you in the ballpark (as long as you maintain the same rear tire diameter.)

    T5 1st gear Ratios- 3.35 or 2.95 ?

    A toploader can be good to about 600hp motor HP. The weak spots of the small block toploader are the 1 1/16" input shaft and the 28 spline output shaft. Replace the input with an aftermarket 1 3/8" shaft (SBF lenght) and a BBF 31 spline output shaft (like found in a BBF) and you will have one...

    1964 1/2 disk brake conversion residual valve needed for rear drums?

    A MC that is designed for front disks and drum rears should have the residual pressure valve built in. You won't see it unless you removed the seat that the drum brake tubing bottoms out against. Best to leave the seat alone. I used the single MC pushrod. Not all have been so lucky so you...
