Just had compression testing of the cylinders in my 65 Galaxie 352. I can find that the compression ratio is listed as 9.3:1 but that does not tell me what should be expected in the way of compression readings. The .
Mind you the minimum cranking compression for a 318 as specified in the factory service manual is 100 psi. I think you should start worrying about compression if you get noticeable blowby out the tailpipe or out the valvecover if you remove the PCV valve. EDIT: If I remember correctly your car had the crappy messed up stock Carter BBD carb. 1967 - 1972 F-100 & Larger F-Series Trucks - Compression tested my 352. - Compression tested the 352 in my 1967 F100.

If the battery is weak or old you may need to charge it up during the test. The battery needs to turn the engine crank at a consistent speed for all cylinders. Hold the throttle plate open and stick a screwdriver down the carb to hold it open during the test.

Duntov understood, perhaps better than anyone, that the 427ci V8’s aggressive design presented the ideal platform for modification. With the addition of an exceedingly aggressive camshaft, the implementation of an increased compression ratio, and the fitment of a larger carburetor, the outrageously powerful L88 was born. Small Block V8 (221, 260, 289, 5.0/302, 5.8/351W) - 1979 302 compression test results - Finally did my first ever compression test, on a rough running 302. Engine was rebuilt about 10,000 miles ago, ran great until suddenly power dropped on highway and started to hiccup. Here are the readings I got: 1- 130 2- 120 3-. Hey guys, I've got a standard 1989 VN 5.0L V8 and have just done a compression test The results were consistent, but seem to be VERY low Seven cylinders were 95 PSI and the other cylinder was 105 PSI (spark plug was darker than the others so I assume this cylinder had a bit of carbon build up which gave the slightly higher compression)
First Generation Camaro Info and Tech - 1967-1969. Engine 305 Compression Numbers . but give N/A for V6 and V8. My vehicle is 1990 IROC 305 (lb9) 9.5:1compression ratio . A compression test is one of the most basic and fundamental engine diagnostic tools, I thought, untill I posted here. Test the first cylinder, and count how many cycles it takes to get to the highest compression reading. For example, it may take 7 cycles to reach 130 lbs. Then test each of the other cylinders, allowing the same number of compression cycles (in this case 7). Record the compression reading for each cylinder. I have been out of the country for a few months and finally got the opportunity to get an idea of the condition of the 260 V8 engine in my newly aquired 1964(65) Mustand convertible (3spd manual trans,PS/PB).

Once forging dies were made it was not cost-effective to test cast parts due to the . mine is like 50 deg ABDC. So "roughly" when the piston is 1/4 of the way up the bore during the compression stroke. If it were at, say, 90 deg ABDC it'd be about halfway up the cylinder, meaning compression pressure would be lower. So with that said, if I stick a stock efi 302 cam in mine (440" SBF), it'd likely crank about 350 psi or so. Doing a compression test, is a good way to measure the condition of, the rings, cylinders, and valves. So, if your engine is running rough or is lacking power, consider doing a compression test.

By comparison, my 302 street car,(9.2 comp ratio) reads 195-210 lbs. With a cam with a lot of overlap,at cranking speed, a high . I have an A-code 289 and I ran a compression test on it before removing it from my '66 fastback. Cylinders 1-4 were around 110-125 psi whereas cylinders 5-8 were about 10-15 psi higher on average. . For example, a head from a '69 351W or certain '68 302's might lower compression by as much as one point, due to a larger combustion chamber.
