    Yeah, exactly the same Kev! I need a pair of hands to get the timing right while the engine is actually running as it's a bit lumpy ATM!

    still the same with that carb mark?

    Right. follow on the other thread (It's in again...), but I have checked the engine with another carb and get the same problems!!

    I can only guess the cam is about right, plus or minus a degree or so, so my problems are elsewhere.

    Oh, BTW Zeph, I tried to find a leak and it's not obvious, if there is one! Checked all ports on the carb and round the manifold, but I was very careful about applying a little sealer round each port on that!

    Still need to check the timing, if anyone has a great idea for an engine not running under 1500 rpm!

    if you got a crate 350 that runs fine,how comes you still want to use the 327 with an unknow cam

    just wondering
    Because the 327 is meant to be a Corvette unit giving 380bhp, according to the readout supplied with thecar, and it came with this engine fitted. Give me a bell and I'll explain....

    Can I borrow the carb, mate? Pretty please??

    Can't you just borrow a HEI dizzy and check it with that although it still sounds to me like an intake leak

    But the engine runs.

    My first job would be to check the pickup in the dissy.
    You can have a gap of 40 thou and engine will not run at low revs.
    You can hane a gap of 15 thou and the motor will run fine at low revs.

    This would be my 1st check.

    Hi Newbold, I wasn't ignoring your post but having the pertronix unit in there I have no gap to adjust. (and it's not really possible to put it back to standard to check old fashioned timing). If I had another dizzy at least I could rule that out. Thank you for your thoughts and input though!!

    Tom, as I said, the dizzy worked on the other engine, so I need to somehow get it running to check the timing and Capt Pugwash has offered another carb to check that, so I'll be contacting him to see if I can borrow it. Just a question of getting it to my place........

    I did ask Simon, but 1/ it's a bit of a cheek, again! 2/ He's working away from home so has little time.

    Anyone local to me who is a Chevy Guru willing to offer me some garage time in exchange for beer/coffee?
