    I'm OK

    Glad to hear you’re ok and the insurers are being supportive. I’m sure you have plenty of mates over there who will give you a hand rebuilding.

    Help with idenfifying my Cam

    Just a quick update. And thanks everyone for your advice. I do listen to everything and take it on board. I have been chasing an engine vibration for almost a year and it got to the point that a strip and balance was the next logical step. when stripping the engine I discovered it had a Crane cam and was seaking advice on it’s characteristics. The engine was not stripped with a major upgrade in mind as I don’t have the budget for it. The engine has never been a startling performer. I received advice from numerous people who seemed to be in the know, saying that the 4V open chamber heads are not suited to low end torque and that I should fit 2V closed chamber heads. As I heard this from quite a few people I sourced a set of 2V heads and had them overhauled. I have not CCed them yet but will do so before I assemble the engine. This was the only performance upgrade I was looking at but as the engine was being stripped I did consider a mild cam. At this stage I am planning on keeping the Crane cam that is fitted. i understand that this is a good opportunity to build a better engine but that is not an option at this stage. Down the track I may revisit that but not this time. The worst part of this is that I got a call from the engine shop yesterday and the engine is ‘in balance’. This was really disappointing news and I am now trying to work out where to go next. Considering torque converter but have conflicting views on whether this can cause my balance issue. I will be talking to a transmission shop to see if they can service/balance it. at $500 to replace it I would like to be confident that it is the issue. I am aware my FMX is not in great condition and had previously made metal but need to hold out as I can’t justify the $2000 for a rebuild at this point.

    Thanks Jet and Barnett. I’m talking to my engine guy at the moment.

    Chasing a Vibration - Flex Plate?

    Okay, just got some really bad news from the engine shop. It is not out of balance. Grrrrrrrr!!!! i need to ponder for a while.

    Help with idenfifying my Cam

    I understand what you're saying but unfortunately I am over budget already. It was only intended to be a head change and re-balance. It would be nice to do a lot more and get the best out of the engine that's not an option this time around. Bare in mind out $ is crap compared to the USD so we pay double what you do.

    Smaller combustion chamber. Greater compression ratio and smaller ports. I'm told give better torque.

    I'm starting to think there may be no great benefit in changing the cam. I will probably pick up enough power with the different heads.

    I know the springs will need to be replaced. They are stock single springs.

    Help with idenfifying my Cam

    I know this won't be much help but this is all I know: Do you want more bottom end power and better throttle response or did it have enough low end power with the current cam? I am chasing more acceleration off the mark. Not concerned about speed. I am on licence number 6 so need to behave. What year are the heads? Unknown. Bought second hand and had them reconditioned. 2V Closed chamber. Non adjustable rockers. Single springs (need to upgrade the springs) What is the part number and mfg of the pistons you ordered? I don't know. The shop doing the balance have ordered them. I know they aren't fancy. Do you mind running 98 octane or do you want to use the less expensive gas? I always run 98. Not worried about the cost of gas. Do you have a stall converter? I don't believe so. At idle and in Drive it lurches.

    Help with idenfifying my Cam

    Thanks Barnett, answers below: How far do you plan to rev it, 4000, 5000, 6000 rpm? Max 5000rpm Do you want an extremely smooth idle like a 1960 Cadillac has/had? Not too concerned about smooth idle but I don't want to loose brakes/vacuum. Currently seems lumpy at idle in Drive. Do you want to roast the bejesus out of the tires (or tires) from a dead stop? Yes please..... but not very often. (traction Lock) What is the cc of your combustion chamber and top of new pistons? Getting out of my depth here. Stock 2v heads and stock pistons. I haven't CCed them yet. What is your gear ratio? 3.25, 245/60/15, FMX What carb and intake? 600 Holley, Edelbrock Performer (Stayed the same due shaker height). Iron manifolds. Will change to headers in a little while once I have paid the bills for current build.

    Looks like you picked it. As I am going from open chamber to closed chamber heads I should pick up a little compression. The shop who are doing the balance are ordering have ordered the replacement parts which should arrive this week. Any thoughts on this cam? If you haven't noticed I know very little about cams.

    Help with idenfifying my Cam

    Thanks guys. I will email Crane and see what they say. Just note, I stripped the engine and it has standard bearings and bore. Ford std pistons. Still has hone marks and no ridge. I find it very surprising for an old engine. I have a very small crack on one piston so all new pistons etc. coming my way.
  13. Hi guys, Just stripping my engine and I've found it has a Crane Cam HMV-272-2A-NC I currently have a 351 Cleveland 4V, Edelbrock Performer and 600 Holley. I have overhauled 2V heads going on. Could I have some advice on the characteristics of this cam and if suitable for a 2V engine. I always thought it had a lumpy idle but wasn't sure if it was a cam or something else

    Chasing a Vibration - Flex Plate?

    Well, engine out and this is the plate. Tomorrow (yesterday for you guys) I will strip the engine and take the lot for balancing. Fingers crossed he will say it was way out. I don't see any point in replacing the flex plate at this point as it will get balance with the crank. Unless you guys suggest otherwise????????
