    Lifter valley oil splash shield in a BBC

    Catbox...yes that's what my understanding of the purpose of the shield is.....to keep the hot oil from splashing up on the intake and heating the fuel and air mixture up. The intake I have right now is the stock TBI intake that doesn't have any kind of plate that's riveted on the bottom of it...

    Lifter valley oil splash shield in a BBC

    Is there an actual benefit of putting one in there? The part number I gave is an actual GM part so they might have had an afterthought?

    Lifter valley oil splash shield in a BBC

    I'm putting a new cam in my 454 TBI engine and when I removed the intake manifold I noticed it did not have the sheet metal oil splash shield that keeps hot oil from getting on the underside of the intake manifold. I'm not talking about the one that rivets to the bottom of the intake...im...

    1989 to 1995 ecm switch

    The original setup is a crappy intake that is an actual carburator intake with that adapter to a TBI. The new one is an actual TBI intake. I found an adapter that goes from 2 wire to 5 wire for the egr on eBay I just wonder if it will actually work. https://www.ebay.com/itm/262666546281

    1989 to 1995 ecm switch

    Bucket...but what about the egr? The 1995 454 has an electronic egr and the 1989 had the regular EGR valve and solenoid. How would I convert the wiring harness to the electronic EGR? Do they make an adapter?

    1989 to 1995 ecm switch

    I've got a 1989 k3500 with manual transmission and it had the Mark IV 454 but I'm putting a 454 from a 1995 into it. I got the computer and wire harness from the 1995 with hopes of just switching my out the ecm but I see that is not possible. Is there a wire harness adapter that would allow me...

    Need help identifying a big block

    So the intake bolts on the vortec big block are not straight up and down like the SBC? Interesting

    Need help identifying a big block

    Bextreme04...I've thought about doing the vortec heads and I've even got a decent set I've found for pretty cheap. But that damn intake that goes to vortec heads and a TBI unit is to darn expensive!!

    Tubetruck...I'll have to check that out. Thanks

    Need help identifying a big block

    Bextreme04...no it's 100% a 9. I've looked at it with a magnifying glass, took an imprint with silly putty, used paper and a pencil and rubbed the numbers on and it's definitely a 9. I'd post a picture of it but I can't seem to post any pictures on this site. Maybe it's got restrictions on new...

    Need help identifying a big block

    Well I took the valve cover off again and peeked down inside the intake valley and didn't see any roller lifter Gizmo/plate so now it's even more confusing!! I've got a generation VI engine block that has a block number not in any database, and it's got a hydraulic cam and lifter set instead of...

    Hey catbox what's your block number? And what side of block is it on? Mine is on the passenger side at the rear of engine.

    Need help identifying a big block

    Well I got ahold of the guy I bought the engine from and he's bringing me the computer and wiring loom that the motor was used with so at least that obstacle is over and done with.

    Need help identifying a big block

    Bextreme04...weren't the peanut port heads strictly for torque in the 454

    Need help identifying a big block

    Bextreme04 that actually sounds like the most logical scenario for that engine. I just wish I could some info on that block number for horsepower and torque ratings and if I need to get a different prom for my truck to that engine or if the existing one will work. Yeah I thought that balancer...

    Need help identifying a big block

    Well this engine has a plastic timing cover with 6 bolts, 1-5/8 freeze plugs, which all point to a generation VI block but it has a TBI intake. The valve train under the covers are non adjustable. The casting numbers in the heads are 12562932 which when I looked up state they came on a mark V...

    Need help identifying a big block

    Bucket....so it could be a roller engine but have regular rocker arms? I thought a roller engine had roller rocker arms as well as the cam? Or are you just implying that the block could be a roller block with provisions to make it a roller but could still have a hydraulic cam and lifter set up...
  19. M

    Need help identifying a big block

    Yes it's a TBI setup on the intake manifold not a vortec. The rocker arms are non adjustable unlike my Mark IV engine. The freeze plugs are 1-5/8 on the new engine unlike the Mark IV block. I read somewhere that the Mark V and VI TBI engines required a higher fuel pressure than the Mark IV...

    Need help identifying a big block

    No idea on bore size as I don't want to tear into motor for just that. The timing cover is actually plastic I believe after looking again and it a six bolt cover as well. Pulled valve cover off and it's not a roller engine...or at least the rocker arms are not roller. My main concern is I need...

    Need help identifying a big block

    Howdy, new guy here and I need a little help. I've got a 1989 K3500 with a 454 and manual 4 speed Muncie tranny. The original engine spun a main bearing so I went a bought another big block engine they was used. The guy said it was a 454 and I pulled it out of an 1994 Chevy K2500. I don't think...
