    Default Olds guys, intake question

    I'm in the process of rebuilding my 455, the long block is going down to timinator to be done up for me. In cleaning my intake I noticed 2 cracks, one on each side of the exhaust crossover, since Tim will either filling or blocking off the exhaust on the heads should I have to worry about the cracks?, have them welded? is this a job for good ole "JB"? I can post pics if needed.

    Thanks in advance.

    What kind of intake are you going to run? I know timminator loves the crosswind, but others on here say it's a POS. I would weld any cracks personally but that's just me...

    What I have now is an offy dual port topped with a Edelbrock 750 that came with the boat, not looking for all out performance, just a good healthy running engine, although I would not mind a little headroom . If another intake is in order, I have no problem with that.

    If Tim is building the motor , Why not ask him about the intake?

    The new Edelbrock Airgap is out for the BBO

    What are you guys running & what kind of numbers are you getting?

    Tim will basically building the bottom end for anything, oil mods, filling the X-overs, big valves & mild cam. Top end is up to me, what I have is as stated in post #3, basset OT headers and a 12jc a pump. Since I live in CO, it would be running, mostly at over 6.5k ft. with an occasional trip to Powell. What would you do? Thanks again for any input!

    Is he building the motor or just doing the machine work? Isn't the heads top end?

    I am interested on what he thinks of that new edelbrock dual plane air gap. Looks like a nice piece. Remember, the intake is an extension of the port job on the heads so why not port that too!

    He is doing the machining and building the long block that includes the stock heads, I meant "top end" as in intake and carb, sorry if I was confusing. As for porting, don't think I'll be going that far right now, as I said just want a good running engine not necessarily a performance one.

    Since the cross overs are going to be welded or blocked off on the heads, the cracks shouldn't be an issue however I would have them welded anyhow.

    Unless I had a bunch of time in porting/port matching an intake, if I found cracks I'd ditch it and get a new one- JMHO.

    Thanks for the input guys-

    OK. ditch the Offy, what are you guys running? what kind of numbers are you getting? I'd like to get something that has been proven, I know there is not much out there for the BBO but curious what peeps overall opinion is.

    Email Mondello's customer service department and give them your engine specs. They seem to know quite a bit about Old's motors!!!
