I'd get some Keith Black HyperEutectics they'll get your pistons higher in the bore and increase compression quite a bit. Funny the 360 KBs are cheaper than the 318 KBs. I think it has something to do with a larger bore and a longer stroke makes for a shorter piston overall. There's a website...
Goto the Comp Cams website called camquest.com you can input all your engines and vehicles specs and it will give you some recommendations on what cams to use and then take all the variables and come up with a close estimate as to how much horsepower and torque your engine will develop. You...
Well I'll just have to get one of them, match it up to my summit cam (sum-6901) and I should get some torque out of my little 318 eh? If I run KBs I should get around 9:1+ CR and 8.5:1 with that cam dynamic, sounds good to me I can run lower octane gas. Gas ain't cheap!
I was looking at those action+ intakes are they worth it? They're much cheaper than the edelbrocks and holleys. I have a T-Quad and its spreadbore, should work.
Vacuum leak maybe? When you let off on the gas vacuum rises way up until it goes back to idle. Try hooking a vacuum gauge up to the intake and check it at various throttle openings including full throttle. Could be a gasket.
I was considering putting a Whiplash Cam from Hughes Engines in my bored .030 over 318 I have, would it be overkill with stock heads? They have quite a bit of lift and not much duration to keep those cylinder pressures up. Probably make some good torque with it. What do you think? I'm going...
That's what I was worried about,a crack, these heads are 40 years old and were kind of rusty, cleaned them up a bit and found that. I'm gonna take a grinder and smooth it out like you said and see if I can find any other imperfections. Thanks to everyone though. I plan running the hell outta it.
Looking for an early 70s Scamp that's in decent shape in the state of Connecticut; preferably close to southeast CT. Planning on working on it so if it needs some work no big deal. Under $1000. Thanks Maybe I'm looking for a needle in the haystack? :-) -Rick
I have read from many different sources that 318 heads on average are in the 62-64 cc range sometimes less, the 340/360 heads had the 74cc and up combustion chambers. I gotta get me a burette and cc my heads I have. They are pre-air port so they have to be older ones. From the casting number...
