Ya I am pretty sure I have at least 8:1 compression. It runs really well and has a lot of get up and go, they guy I work for is a car nut and has 9 classic muscle cars including a 79 corvette with a 355hp 350, 67 gtx with a 375hp 440, and a 67 el camino with a 425hp 427. I've driven them all a...

yes i did.. do the ... mean that's bad? that's what all the tune up specs say to do. anyways I found this paragraph on this website. I said I was getting 16 in of HG in my manifold and indeed they say 16-18 is normal. All engines require an acceptable air/fuel ratio to run properly, even at...

Ya I think if I want to do anything it'd be to keep my eyes out for cheap 318 heads but it isn't a daily driver and If I wanted fuel economy I wouldn't have bought this car to begin with haha. I just tuned the carb myself today, front float bowl was way high and secondaries were low, then I...

Ya i probably wont be really messing with the engine, i'm only 17 and have been building it for 16 months haha heck I want to drive it now before I got to college in 6 months. Any money I could put into this engine will go to a 360 stroked to a 408 someday, I only built up this one because the...

I don't really have the funds right now to buy a new carburetor anyways. It sounds like the Cam and intake are okay it's just my low compression and possibly mixture and jets. Can I fix my compression problem by having my heads ground down or do I need to pull the engine and have the block decked?

SO in you guys opinion what should I do? I am starting body work and getting ready to paint the car soon. I'd really love to not pull the engine. Can I take off the heads and have them decked a bit more to raise my compression to 9:1 or so? and then have my carb professionally tuned? Would those...

Are you in the portland area? I live up north of vancouver in Ridgefield Wa. I'd love to find someone who knows what they are talking about and help me tune this properly, ideally with a dyno
