As you say Julian coolant leaks in this area are frequently coming from the distribution cover. Several reasons can be at the origine of this problem: - poor watertightness due to the aluminum cover sealing surface corrosion (old liquid cooling was without inibitor) - poor watertightness due to...

Interesting subject! As I have built a SBF aluminum block I can tell you that it is true, there are several oil leak possibilities. However, as it was previously mentioned, if you have a carefully building operation, you will obtain a good result. First of them, we have to keep in mind that...

Jim is right, both cranks can be installed on a 289 block. However, there is 2 kind of 302 cranks. The early heavy (until 1981 I believe) that are 28OZ externally balanced (like the 289) and the last (1982 and after) that are 50OZ externally balanced (they are lighter). It means that if you keep...

Scott, I agree with you.... But only for your last sentence :D As you say, the best way is to use a thermostatic 4 ways valve to have a constant working oil temperature. Oil radiator as well the oil sump volume should be sized to keep the oil temperature at a constant value what ever the...

Hi Dean Your induction project looks very nice but will not be easy if you select the Weber option. The main difficulty is to find a special manifold to adapt Weber carbs on Yates cylinder heads. Furthermore, with a 8.7" deck height block there is very few manifolds available on the market. I...

I fully agree with you Cliff, it is the stronger argument ;)

Hi Chris I agree obviously with the previous pertinent answers but we have also to note that the casting is not very nice. According to the picture the thread looks like it was moved forward of the center. It means that one edge is too skinny that weaken the thread. Furethermore, the casting...

Yes Ron it use an index. Fortunately, my engine is dismantled and I do one picture to show the pin. But be careful, this part is not a "bolt on" type. I have spend some time on my lath to adapt it :rolleyes:

You are right Larry, it is probably this second possibility. Water pump impeller could be disconnected of the pump shaft even if it is not a frequent trouble. If the heating in the car doesn't work, it means that the water pump is out of order :o

Paul, your problem looks like if your thermostat was blocked in closed position. To be sure, you have to remove it (empty partially your radiator before to open the thermostat housing) and to test it. Test can be done as follow: Put it in a saucepan of cold water, then heat it on the cooker and...

Hi Ron, First of them, I have to congatulate you for this forum spirit! It is always a pleasure to read some informations and to see some original pictures (even if I don't write too much :o ) As you know, some race engines have to use mechanical fuel pump according to their relevant...

351W with destrocked crank is a good way to have an high revs engine. As in Nascar configuration, you can use a 3.25 or 3.35 stroke crankshaft with long rods to produce a 330 or 340CI able to perform safely 8000rpm (without the 302 short rods problems). However, I don't understand why you...

It is obvious that maximum fuel flow capacity is only requested for the maximum power demand. Then I am not talking about fuel flow average but about fuel flow peak. It is a fact: if you expect a powerfull engine performances you have to design all parts of your car according to the stronger...

Hi Simon Regarding the damper, you have to indicate what kind of 302 version you have. The first generation (until 1981) was equipped with an heavy crank and the external balance (as well on the damper as on the flywheel) was 28 OZ. The second generation (1982 and later) was equipped with a...

Hi Sandy I bought this bloc 4 years ago at fair price from a local racing dealer in the States. To be honest, I don't know exactly the right reference (I don't receive back from the dealer any document nor information). We can see in the front a small Ford logo (from casting) and in the starter...

Weber carbs are a master piece of the Ford legend engines. So when I had planed to build a Cobra replica I had selected a Weber set. As I had Yates head cylinders, it was necessary to create a special inlet manifold to adapt it. Big job :o . I have selected the 48IDF type instead of the...

My age indicator needle is going to the "glove box" (and I have a left hand drive car), I am 59 :o ... but I look 57 :D

Hello Dave 5/8 and 3/4" clutch master cylinders are usual values to have the best relation between pedal travel, pedal effort and "progressivity" (note sure about this word :o ). However, we have to take car about the "pedal ratio" that is the distance between pedal axle and master cylinder rod...

It is a common practice in racing engine to switch off the ignition when there is a risk of mechanical damage. At the top level, we use this arrangement in formula one engine. As you know, formula one engine are without valve spring. Valves are closing and maintained closed only by CO2 gas...

I don't have a GT40 car but she is his old sister :) She is also powered by Ford (with some personal arrangements) 302 RDI aluminum block 8.2 deck Dry sump Yates cylinder heads Modified intake manifold for Weber 48 IDF :pepper: Bored to 4.120" (siamese cylinder) Stroke: 3.25" Displacement ...
