What should compression ratio be on 305 engine?
What should compression ratio be on 305 engine?
They have relatively small combustion chambers, and the basic engine sports compression ratios of 9:1 or more. These heads will port out well, but be aware that 305 heads have smaller valves, so only look for 350 heads unless you’re specifically working on a 305. This will save you the expense of extra machining to put in larger valves.
What’s the difference between 305 heads and 350 heads?

What’s the compression ratio on a Mopar 318?
As far as the compression ratio, 318’s are NOTORIOUS for having taller decks than the factory spec’d, leaving the pistons down in the holes to begin with.
What kind of heads do you use on a 318?
The 318 works much better with the Swrl port heads from the later 318s . Like a 87 Fifth avenue 318 head etc. basically the first gen roller cam engine heads for a rule of thumb. How much better? A lot better. I remember and may still have it in the pile that Hot Rod mag did a 318 project several years ago with Arruza motors (sic?)

Which is the best camshaft for a small block Ford engine?
A kit provides a no brainer solution that ensures you’ll have components that work well together. There seems to be a greater variety of roller-tappet camshafts available out there that allow you to dial in ford performance engines. The nice thing about roller cams is the aggressiveness they offer without sacrificing idle quality and drivability.
What happens when you put too much pressure on a camshaft?
Shorter duration increases cylinder pressure. Too much cylinder pressure can cause detonation (pinging), but have too little and you lose torque. You can count on cam manufacturers to figure stock compression ratios into their camshaft selection tables, which makes choosing a camshaft easier than it’s ever been.
What kind of camshafts did they use in the old days?
Let’s talk more about cam selection and choices. In the old days, we had two basic choices – mechanical and hydraulic flat-tappet camshafts. We went with mechanical camshafts whenever we were going to spin the engine at high RPM.
